A solar-powered way to clean stormwater

by Stephanie Basalyga

An Oregon product designed to provide clean drinking water in Third World countries may also hold the solution to a problem that plagues construction sites: how to clean stormwater. Beaverton-based Puralytics first caught widespread attention when it unveiled the SolarBag. The bag, which uses sunlight to clean contaminated water, has been used in 60 countries around the world, according to Mark Owen, Puralytics’ CEO.

Owen’s company is now working on an overgrown version of the SolarBag. The new product, called the LilyPad, is in the spotlight for its potential to not only clean large sources of water in impoverished countries and disaster areas, but also serve commercially viable markets such as construction and agriculture. Owen, a self-described “serial entrepreneur,” started Puralytics seven and a half years ago with an eye toward using LED light to activate nanotechnology to purify water. That early search resulted in a product called the Shield, an LED-powered purification system designed for decentralized drinking water systems, multiunit housing or small-scale water stations. Even as they developed Puralytics’ first product, Owen and his staff began to ponder whether they could replace LEDs with sunlight to purify contaminated water. Their search resulted in the creation of the SolarBag.

The SolarBag quickly caught the attention of the tech community and captured a string of awards for Puralytics, including a grand prize for best clean technology business at the 2010 CleanTech Open. But Puralytics wasn’t done noodling ideas for better – and bigger – ways to clean contaminated water. With a 3.5-liter capacity, the SolarBag was limited to producing a maximum of 10.5 liters of clean water per day – enough for a single person. Owen and his staff wondered if they could make a larger version of the bag to clean a much larger volume of contaminated water.

“The question was: How big could we make it, and could we treat the water source?” Owen said.

At the time, Owen figured the product that would become the LilyPad would again find its main purpose in areas where pure drinking water is a problem. Owen envisioned it being used mainly in open-topped water tanks and ponds. But as he talked to people about the product, he soon realized it also might have commercial potential.

“There’s been tremendous interest from the (construction) industry,” Owen said. “We’re looking at its potential to clean stormwater, to clean water used on farms for crops.”

Creating a product for widespread use in a commercial market would be a big boost for Puralytics. The high costs associated with developing technology – the SolarBag and LilyPad both rely on a combination of five processes – require tech startups like Puralytics to rely on investors and funding from sources like Oregon BEST.

Money from Oregon BEST, which works to direct research revenue from multiple sources to companies in the state, helped Puralytics work with Oregon State University to conduct an initial phase of research on the LilyPad.

“The LilyPads are designed to float on the water surface,” said Tyler Radniecki, an assistant professor of environmental engineering at OSU. “We did some lab tests with (collected) stormwater and found that four inches of standing water is the ideal depth.”

Armed with that information and $94,000 more from Oregon BEST, Radniecki is ready to start a second phase of LilyPad testing for Puralytics. The testing will be done in a rain garden area at the OSU-Benton County Green Stormwater Research Facility in Corvallis, which will allow Radniecki and one of his students to study how the LilyPad stormwater treatment technology performs in real-life conditions.

“(The facility) has all the bells and whistles as far as monitoring,” Radniecki said. “We can measure water flow, sunlight. For Mark’s technology that I’ll be testing, that will be critical – how the sunlight intensity affects the rate of contaminant absorption. “(The LilyPad) is designed for more than one-time use, so we’ll (also) be looking at how long they last, how leaf debris that falls on top of it affects it.”

For Radniecki, the LilyPad testing results will provide material for papers for peer review in scientific journals and a topic for his assistant’s master’s thesis.The tests also promise to provide civil engineers with information about ways to make it easier to maintain rain gardens, according to Radniecki. Rain gardens often are used to help clean stormwater, but they require a high degree of care.

“Maintenance is a big thing with rain gardens,” Radniecki said. “A rain garden needs the grass mowed. You have to clean the silt. You have to take care of the plants, but a lot of times that doesn’t happen.”

During the testing phase, Radniecki and his assistant will examine whether the presence of the LilyPad changes the amount of maintenance that needs to be done to keep the garden in proper working order. As for Puralytics, if the testing upholds expectations, the company will be able to walk away with what it says is crucial for earning recognition – and commercial acceptance – for the LilyPad.

“One of the challenges is that you need third-party certification and a qualified lab to talk about results,” Owen said. “The industry really wants to see that. “This is going to help us cross that gap for internal testing to formal field training with a well-monitored application in a public setting. It will give us the (real world) data. That’s essential.”


Puralytics® earns Global Honour Award from the International Water Association

IWA cites Puralytics’ solution to provide access to safe drinking water in Malawi project

 Beaverton, Ore. - The International Water Association (IWA) has announced that Puralytics®’ SolarBag® will receive its Global Honour Award for Drinking Water Supply (Hardware Category) for its innovative solution to providing access to safe drinking water.  The IWA will present its 2013 Project Innovation Development Awards Oct. 15 in Nairobi. The award will jointly recognize Puralytics and Good Samaritan Ministries for their combined work to implement and administer this uniquely successful drinking water project across Peri-urban Malawi.



“Many regions in Malawi, Africa are struggling with access to safe drinking water,” said Puralytics CEO Mark Owen. “Urban areas are often subject to tap water supplies of little to no water treatment while the surrounding rural communities may be forced to drink from untreated and poorly maintained wells and bore-holes.  With that, we wanted to demonstrate how our technology could be used in Malawi and across Africa as an effective, flexible and low-cost drinking water solution for both difficult urban and rural, remote situation needs.”

The SolarBag, developed by Puralytics, is a reusable water purification device that uses a sunlight-activated nanotechnology to produce up to 9 liters of safe, drinking water each day.  Its award-winning design has the broadest contaminant protection available, removing heavy metals, destroying chemical contaminants like pesticides and petrochemicals, while also eliminating bacteria, viruses, and protozoa while exceeding EPA water purifier standards.  As such, the 3-liter SolarBag is the only non-powered, non-chemical device that actually meets both the World Health Organization (WHO) standards for safe drinking water and the SPHERE international guidelines for individual daily drinking water quantities. 

“Good Samaritan Malawi (GS Malawi) already had an established presence working in the Bolero and Mzuzu regions of Malawi and had been evaluating options to empower residents with access to safe drinking water by introducing new and sustainable methods for water treatment,” said Jill Hartzell, GS Malawi country leader.  “Puralytics and GS Malawi worked together to distribute and monitor Puralytics’ SolarBags to the Malawians participating in GS Malawi’s network of village programs.”

SolarBag usage and performance information was relayed back though GSM to Puralytics every month since the project’s implementation in late 2012, with overwhelmingly positive results:

  • User training proved to be very successful, resulting in only four reported cases of improper use in four villages.
  • Product adoption showed the SolarBags were used multiple times per day over a 9-month period since late 2012, with 92 percent of the SolarBags continuing to function normally.  
  • More than 82 percent of the users said they drank more water after receiving their SolarBag and 89 percent claimed they felt sick less frequently.  
  • More than 91 percent acknowledged boiling less water for treatment, reducing their expenses for fuel and more than 96 percent said their water tasted and smelled better after using the SolarBag.

The SolarBag is uniquely effective as the only water purifier that's proven to remove virtually every lethal toxin found in contaminated water, including gasoline, diesel fuel, pesticides, herbicides, toxic heavy metals like lead, arsenic, cadmium, and mercury, and pharmaceuticals like artificial hormones and animal antibiotics. The nanotechnology is activated by UV sunlight and therefore works on both sunny and cloudy days and does not require any external power source, consumables or chemicals

The SolarBag is easy to use. Users need only fill the SolarBag with water and leave it exposed to the sun for a few hours, allowing it to be used multiple times per day.  The empty bag can be stored for up to 7 years and can be reused hundreds of times, making it ideal for both emergency response needs and as an ongoing, affordable solution for rural or remote situations.

“This investment reflects the growing market need for cost-competitive solutions that deliver access to clean, potable water,” said Puralytics CEO Mark Owen. “Our investors see the economic opportunity, as well as the social impact, that our water purification technologies offer.”

“The funding has enabled us to further bolster our company’s foundation and team,” added Owen. “To date, we’ve already introduced two products to market and are in the early stages on a third. And to meet growing demand, we’re also expanding our manufacturing capabilities to support a qualified sales pipeline of $20 million.”

Puralytics develops innovative products that help both the Developing and Developed World meet their growing water needs. The company’s current product focus includes: the SolarBag, Shield and LilyPad:

The SolarBag is a personal water purification device with a patented process that uses sunlight to activate a nanotechnology mesh that removes bacteria, viruses, heavy metals, and chemical contaminants and is the first non-powered, non-chemical system to ever exceed the requirements set by the U.S. Environmental Protection Agency’s Standard and Protocol for Water Purifiers. Last month, the International Water Association announced that Puralytics' SolarBag received its Global Honor Award for Drinking Water Supply for its innovative solution to providing access to safe drinking water in Malawi. To-date, the SolarBag has been sold in more than 50 countries and is available for purchase online and through a growing number of retail outlets. 

The Shield is a low cost of ownership and broadly effective advanced water purification system. It’s designed for decentralized solutions for drinking water, industrial waste polishing and laboratory water applications using LEDs, advanced optics and nanotechnology, treating up to 1,000 gallons of water per day. The Shield has been deployed in 11 counties through Puralytics growing network of distribution partners. 

The LilyPad is a sunlight activated solution that addresses contaminants from storm water run-off and from other industrial waste water sources in retention ponds. Still in its implementation phase, Puralytics was awarded an OregonBEST grant, courtesy of the Oregon Built Environmental and Sustainable Technologies Center, and is working with Oregon State University to test the LilyPad and bring the technology to a marketable product.

Puralytics® Awarded US Patent for LED Activated Nanotechnology Water Purifier

Light Activated Nano Technology broadly effective for destroying contaminants, features efficient operation and no waste water discharge

download (1).jpg


 Beaverton, Ore. - The US Patent and Trademark Office has granted Puralytics a patent for a light activated nanotechnology which can both disinfect and detoxify water. Puralytics’ patented process can employ either sunlight or LED light to stimulate a nanotechnology coated mesh activating five photo chemical processes to eliminate all three major categories contaminants, including biological pathogens, chemical contaminants, and heavy metals toxins.  The patent covers both the method and apparatus of purifying water using multiple wavelengths to activate a semiconductor photocatalyst attached to a fibrous mesh.

“This patent recognizes and protects our innovative technology and also the uniquely applied product concepts we are bringing to the market,”  said Puralytics CEO Mark Owen.  “Puralytics technology in one process exceeds the contaminant removal of what historically has taken multiple, other combined systems to address.  Moreover, we accomplish this by actually destroying the most difficult contaminants from the environment, rather than just filtering and discharging these problems right back into our ecosystem.”  Dr. Tom Hawkins, Principal Investigator and co-author of the patent added, “Accordingly, we believe this technology and our products represent a sustainable future for water treatment by making pure water possible in places and applications not possible before.” 

Puralytics technology is currently being marketed in both LED Activated and Sunlight Activated product formats, including the Shield, SolarBag 3L, and LilyPad products, respectively.

Solar tea bag takes garbage out of water

by Joseph Gallivan 

The coming water crisis — oceans too high, lakes too low — overshadows the current crisis of a billion of the world’s people lacking clean drinking water. A Beaverton startup has a deceptively simple solution to the immediate problem: a device that can clean water with little energy use. Puralytics new solar-powered Lily Pad invention looks like a big nylon teabag, designed to float in ditches and ponds. It removes all the revolting stuff in runoff from roadways — plastics, metals, bacteria, pesticides, petrochemicals, peed-out pharmaceuticals — while just lying there.

“Historically, the solution to pollution has been dilution,” says Mark Owen, CEO of Puralytics. “Get the stuff to a stream or a lake. But we’re getting to the limits of that thinking.”

Puralytics won a $53,000 grant in April to test the Lily Pad and nudge it to becoming a marketable product, courtesy of the Oregon Built Environmental and Sustainable Technologies Center. The state-funded consortium of academic researchers, known as Oregon BEST, aims to develop and nurture clean tech industries. The money is helping Puralytics work with Oregon State University’s Institute for Water and Watersheds to see if the Lily Pad is feasible. The first phase ends this month.

The grant is part of a $1 million round of commercialization grants from Oregon BEST for promising clean technologies. Puralytics’ first product was the Shield, a box that looks like a tower PC being fed water. Inside, LEDs do the work of sunlight, and clean water flows out the other end. The company’s market is not just high-tech manufacturers. Every Starbucks has a water purifier to make sure the coffee tastes the same everywhere. Restaurants and apartment buildings have them, or any business that doesn’t trust the water mains. Puralytics just shipped a unit to the Sands/Venetian Hotel in Macau, China. It’s a pilot program to see whether they can recycle more water in the kitchens of the giant casino. Another is going to a village in Vietnam. It will be a self-serve kiosk where people can pay by cell phone and fill their drinking water container. It has to be foolproof and low maintenance, but the demand is there.

Another product has taken Owen in a different direction. Puralytics makes a three-liter plastic bag with a mini version of the mesh inside the Lily Pad. Filled with water and placed in the sun for three hours, the Solar Bag creates clean drinking water out of some dodgy stuff. Microbes and parasites die, too; their cell walls are torn apart. Owen now sells the Solar Bag in more than 50 countries, usually to nonprofits, foreign governments and faith-based organizations, such as the International School of Beaverton’s trial in Yucatan, Mexico, or Good Samaritan Ministries in Malawi, Africa. Campers and backpackers also buy the Solar Bags, which retail for about $75. Nonprofits, known abroad as nongovernmental organizations, qualify for a discounted price.

“Unlike here, people in the developing world sterilize their drinking water at the faucet,” Owen says. “The work of digging wells is being done by NGOs and faith-based organizations.”

He likens this to distributed computer systems, how we all rely on smart devices in our pockets instead of our grandfather’s mainframes. “It became a distributed solution once the mind-set changed,” Owens says, suggesting the same mind shift is due with water. In the United States, the Solar Bag is being discovered by backpackers. Owen used his in the Grand Canyon this year when the park service’s water main went down. His peers used iodine. Owen’s backers for Puralytics have been classed as “LOHAS,” or people aspiring to Lifestyles of the Healthy and Sustainable. “It’s impact investing,” he says. “People are looking for the triple bottom line: financial return, good for the environment, and good for people.

“The world doesn’t have great solutions for taking contaminants out of the environment,” Owen says. “Or even in our bodies. You can measure pesticides in our blood, and over time that’s not sustainable for the health of the planet. We can’t solve all problems, but we can solve how pesticides get into water, and treat contaminants at trace levels. That’s how I see us making a contribution to the world.”

Water purification startup Puralytics aims to widen sales reach in 2013

By D.K. Row

One of the many lessons learned from Superstorm Sandy was the importance of water during natural disasters -- clean water, specifically.
Water was everywhere after the hurricane. But most of it was unsafe to drink and use. These are problems Mark Owen  has thought about for some time as an inventor and entrepreneur. His startup, Puralytics,  sells water purification products based on sunlight and LED-activated nanotechnology. In its fifth year, Puralytics has spent most of the past two years refining its product technology and building the company's infrastructure.
Now it's ready to pursue consumers in different sectors, including companies in need of water for industrial processing, non-government organizations working in developing countries, and individuals needing it for recreational use and emergency preparedness kits that could be useful during natural disasters.

"2013 will be about scaling up our sales," says Owen, a Beaverton resident and Oregon native. "We will or should hire more staff and expect to increase sales ten times over what it is right now."

Puralytics produces four products. Each uses sunlight or LED light to break down and destroy contaminants in water for human consumption or use in laboratories in the life sciences, pharmaceutical or semiconductor industries. The SolarBag  model, for example, uses sunlight to detoxify drinking water and make it safe to drink, while the Shield 500  does the same thing using LED light technology. Another Shield model, the Shield UPW,  also uses LED technology but purifies water for industrial and research processes. Water purity at this level is technically purer than drinking water but also not recommended for human consumption.

Both Shield models can purify as much as 500 gallons of water a day, while the two SolarBag models take a few hours to purify three liters at a time. Cost varies, too: The bigger Shield models start at $9,000 and top out at $12,000, depending on the application. The SolarBag is priced at $80  on Amazon.com. The SolarBag 3L  is used mainly by aid organizations which purchase it in volume.

Owen says laboratories and chipmakers internationally have purchased Shield UPW  models while the two SolarBag models have customers in 43 countries. SolarBag is carried by Amazon and Sportsman's Guide, among others. He's hoping to grow sales by finding more retail outlets and distributors next year, as well as expand the international presence of the SolarBag 3L. The 53-year-old is not only Puralytics' founder and chief executive, he's also its main inventor with more than 30 issued or pending patents to his name. A graduate of Oregon State University's mechanical engineering program, Owen has worked in business development, marketing and engineering management roles at Agilent Technologies,  Tektronix  and Electro Scientific Industries,  among other companies.

In 2002,  he founded Phoseon Technology,  which provides ultraviolet LED photo-curing systems to the coatings and adhesives industry. Owen's still a director at the multimillion-dollar company but left as its CEO at the end of 2006  to start Puralytics. Puralytics began as a problem-solving exercise between Owen and two other inventors. The problem: How to find a business opportunity in the air or water purification space that would "have a high impact on the world."

Eventually, Owen's brainstorming partners chose to go in another direction and Owen pursued his idea on his own, spurred by an "aha" moment in Tokyo when he saw a building with a self-cleaning coating on it. Owen spent the next three years conducting research, securing investors and grants -- including those from the U.S. Army, Onami, and the National Science Foundation  -- and building prototypes before unveiling the first Puralytics product, Shield 500, in 2010.  

Owen won't disclose sales figures but says 2012 has improved upon 2011, and that numbers have been impressive overall for a startup that's spent most of its time building technology and staff. Currently, the Beaverton-based company employs seven full-time and six part-time staffers. Puralytics has also been acknowledged by the cleantech industry. It was recently named a Global Cleantech Top 100  company, while Inc. Magazine named it a top water investment for 2012.

In early November, Puralytics got another financial boost, receiving most of the money awarded to Oregon companies in a recent funding cycle from Keiretsu Forum Northwest,  the Northwest chapter of an extensive angel investor network that has chapters worldwide. Keiretsu leads the investing for the startup's Series A funding drive worth $4.5 million. If things go as planned, Owen expects the company to become a buyout target. In such cases, founders usually exit, but Owen would like to stay on.

"Once you take on investors, you are implying there is an exit," Owen says. "But I'm planning to stay with this until the end, whatever that is. That's a ways away, anyhow."


The Future of Water: Mark Owen at TEDxOSU

Mark Owen is an OSU Mechanical Engineering graduate and has a Masters of Technology in Advanced Manufacturing from the University of Limerick Ireland. He is an inventor and entrepreneur, and was the founder of both Phoseon Technology and Puralytics. Puralytics has developed a water purification technology and products which are sustainable and have applications in both here and in the developing world.

CleanTech Open 2010 Prize to Puralytics

Beaverton, Oregon, USA

Puralytics, an emerging leader in advanced water purification technology for light industrial applications, was named the winner of the CleanTech Open 2010 prize at their Awards Gala on November 17th in San Jose.  Puralytics was selected by the judges based on four main criteria: Idea Concept, Innovation, Business Viability and Sustainability.

Mark Owen, Puralytics CEO, was elated and surprised to be named as the first water sector company to win this coveted award.

The same day, the U.S. EPA announced plans to test for 134 chemicals thought to disrupt the human endocrine system.  According the EPA Administrator Lisa P. Jackson, "Endocrine disruptors represent a serious health concern for the American people, especially children. Americans today are exposed to more chemicals in our products, our environment and our bodies than ever before, and it is essential that EPA takes every step to gather information and prevent risks.”  Puralytics’ new process effectively destroys these difficult compounds, a unique capability in water purification.  Additionally, the process sterilizes bacteria, viruses, and other pathogens and removes heavy metals such as lead, arsenic, mercury, and selenium.  Essentially, all of the health related contaminants are eliminated in a small, simple, and easy to integrate system.

This award follows several other recent accolades received by Puralytics.  A panel of industry experts named Puralytics as the Water Investment Idol at the American Water Summit 2010 Conference in Washington DC earlier in November.  Also, the Artemis Project selected Puralytics as one of the Top 50 Global Water Technology Companies in 2009 and 2010, and they were a national finalist in the 2010 Imagine H2O business plan competition focusing on water efficiency.
