BioLargo Engineering Is Tackling PFAS Head-On With New Treatment Technology — Moving To Next Phase Of Groundbreaking PFAS Work

Oak Ridge, TN – BioLargo Engineering, Science & Technologies (BLEST), today announced that it has validated the efficacy of a new, cutting-edge water treatment technology aimed at solving the growing international per- and polyfluoroalkyl substances (PFAS) contamination crisis. Having completed its work under a Phase I SBIR grant from the EPA to its parent corporation BioLargo, Inc. (OTCQB:BLGO), it is moving to the next phase of development in preparation for demonstration pilots and commercialization.

The new technology, called the Aqueous Electrostatic Concentrator (AEC), has been proven capable of 99+% removal of the two most predominant PFAS compounds – PFOA and PFOS – without the need for the high-pressure systems and high electricity costs of reverse osmosis, or the high consumable costs necessary for carbon filters. BLEST reports that based on its bench-scale testing, AEC was projected to use only $0.30 of electricity to treat 1,000 gallons of water, a fraction of the cost of what is necessary to operate the competing technologies. BLEST management believes that they will further reduce electricity costs for treating potable water.  

Described as “forever chemicals” by Washington DC based environmental watchdog the Environmental Working Group, PFAS contamination is estimated to affect up to 110 million people in the United States. Numerous experts have linked PFAS to detrimental effects on human health and the environment due to their tendency to accumulate and persist in the environment and human body. On January 7, 2020, EPA Administrator Andrew Wheeler announced that “aggressively addressing per-and polyfluoroalkyl substances (PFAS) is an active and ongoing priority for the U.S. Environmental Protection Agency.” The two common and widespread PFAS compounds addressed by the BLEST study – PFOA and PFOS – are found in common household and industrial products. Both compounds have been found in water supplies across the country, and municipalities are struggling to find a feasible and affordable solution to remove PFAS from their drinking water.

Funded in part by an SBIR Phase I grant administered through the EPA, BLEST’s initial work successfully established that the AEC could remove high concentrations PFAS in a continuous flow-through device, producing a “clean” stream and a highly concentrated PFAS stream ready for subsequent treatment by methods like advanced oxidation. The AEC technology has potential to significantly reduce the cost of water treatment in a full-scale application.

The BLEST team has submitted an application for additional funding from the EPA to accelerate its work under a Phase II SBIR grant. In the proposed project, the team will create a pilot unit to field test the technology in commercial and industrial settings at a small commercial scale. They are in the process of identifying a “partner community” that will act as the test site.  

Randall Moore, President of BLEST, commented, “We believe we have made a strong case in our application to the EPA for additional financial support under the Phase II SBIR grant program. Our team has decades of experience delivering engineering and science-based solutions. Our goal is to deliver a low-cost, low-energy technology that will reduce the threat PFAS poses to people worldwide.”  

BioLargo, Inc. President & CEO Dennis P. Calvert expanded on the commercial implications of the AEC, “We believe a solution to the PFAS crisis is directly in line with our mission, knowledge and experience. We have confidence in Randy, his team, and our group of scientists, and intend to support BLEST 100% as they move towards commercializing the AEC. We plan to get the technology field tested and launched commercially as soon as possible. We have the ability to help communities all over the world who face this PFAS challenge. This is another great example of how BioLargo has grown to become an innovator and full-service solution provider.”

EPA Publishes Report Highlighting BioLargo Engineering’s PFAS Technology Project

Last year, BioLargo Engineering, Science & Technologies (BLEST) was awarded an EPA SBIR grant to fund the company’s efforts to create an effective, affordable solution to the global per- and polyfluoroalkyl substance (PFAS) contamination crisis. The project was in collaboration with leading environmental scientists at the University of Tennessee.

These efforts were successful – in 2019 BLEST developed a working prototype of a device called the Aqueous Electrostatic Concentrator (AEC) that was proven effective at eliminating PFAS from water in continuous flow. In fact, the AEC was shown to eliminate more than 99% of PFAS molecules from flowing water at an approximate energy consumption cost of less than 30 cents per 1,000 gallons, which is estimated to be highly competitive compared to alternative technologies.

We are now proud to announce that the EPA has published a report detailing the successes of this project on their website. You can read the report here:

https://cfpub.epa.gov/ncer_abstracts/index.cfm/fuseaction/display.abstractDetail/abstract/10966/report/F

The report concludes, “The study demonstrated the ability of the AEC to remove over 99 percent of total PFOA and PFOS from the feed stream.  During testing the AEC was operated at conditions that would provide a theoretical concentration factor up to 35 times, based on the ratio of Feed Chamber rate to AEM Chamber rate when operating in flow-through mode.  With additional testing, higher concentration factors are expected to be achieved.”

Stay tuned for more updates as BLEST works to scale up and commercialize the AEC technology to start treating PFAS contamination problems that are currently affecting countless Americans.

An NWRI-BioLargo Fellowship Success Story

Source: NWRI

The National Water Research Institute (NWRI) has, for many years, offered fellowships to graduate students in the US whose research focuses on—you guessed it—water. These fellowships are typically sponsored by companies who develop water-related technologies and are meant to help propel the careers of up-and-coming water scientists and spur innovation in water technologies. Today’s article highlights one of these graduate students—Jianfeng Zhou of the Georgia Institute of Technology—and how his NWRI fellowship is helping move his research and his career.

One of the goals of these NWRI fellowships is to promote exposure to innovative private companies in the water industry, creating opportunities for fellows to apply their research skills in the context of private industry. For Jianfeng (Jacob) Zhou (LinkedIn profile), his fellowship gave him the chance at an internship with the company who sponsored his NWRI fellowship in the first place—BioLargo, Inc. Jacob is a third-year PhD student in Environmental Engineering at the Georgia Institute of Technology in Atlanta. His NWRI/BioLargo-funded research focuses on developing novel advanced water disinfection technologies that overcome the downsides of the most common disinfection technique worldwide, chlorination.

“Chlorination is really easy to deploy and very cheap, but its biggest problem is that it generates by-products that can cause health problems like cancer. That’s a big problem worldwide. Our research attempts to solve this problem by developing new disinfection methodologies that potentially don’t create by-products,” commented Mr. Zhou. “The technology we’re working on uses an enhanced electric field that penetrates the membranes of bacteria without leaving any by-products. It uses special nanowires to achieve this without consuming too much electricity.”

The technology Jacob is working on in his PhD shows real promise, and his research acumen caught the eye of BioLargo, Inc., the underwriter of his NWRI fellowship, and a developer of novel water technologies. BioLargo offered Jacob an internship at its engineering division BioLargo Engineering, Science & Technologies (BLEST) to work on some of BioLargo’s own up-and-coming water treatment technologies and to deploy his water science skills in real-world environmental engineering challenges.

On his experience at BLEST, Jacob commented, “It was great. BLEST has a very experienced team, and it’s great to learn how a small but seasoned team solves water challenges. In academia, sometimes you are focused on the novelty and innovation of a new technology or concept, but it doesn’t always see the light of day in real application. At BLEST, I had the chance to witness the practical, real-world implementation of solutions to water-related problems. I thoroughly enjoyed my time at BLEST.”

The President of BioLargo Engineering, Randall Moore, was also very pleased with the opportunity to collaborate with Mr. Zhou in his internship, “Jacob is a very bright and promising scientist. He brought a lot of value to BioLargo Engineering during his internship, and I’m certain he will bring a lot of value to groups he works with in the future – whether they be academic labs or water-focused companies like ours.”

Following Jacob’s internship at BLEST, BioLargo, Inc. CEO Dennis P. Calvert was singing praises for NWRI’s fellowship program, “I am very impressed with NWRI for its ability to select talented researchers for the fellowship, as evidenced by our experience with Jacob. We feel that the NWRI/BioLargo fellowship clearly makes an impact in the innovation ecosystem that surrounds the water industry, and we’re proud to be sponsors alongside this great, innovative organization.”

Jacob’s experience with the NWRI/BioLargo scholarships illustrates the potential power of funding programs like these and is an example of how academic/industrial collaborations help to fuel water innovation. In Jacob’s words, “[he] originally got interested in water science because he wanted to make a contribution to society and to public health by improving water treatment technology”. His impressive work at Georgia Tech and the internship at BioLargo, a budding water technology innovator, suggest he is well on his way to achieving that goal.

Waste Advantage Odor-No-More Article: Odor Control Best Practices

The following article was published on January 2nd, 2020 in Waste Advantage Magazine (and online). To view the source version, go here.

Keep learning new tips and tricks every year and you will be sure to stay ahead of your odor challenges.
By Joe Provenzano

The world of waste handling is changing. In years past, landfills could operate with little to no impact on neighboring communities, but this is often not the case today. Over the years, landfills have evolved through engineered expansion and many have grown into “mega-landfills” that not only have ballooned outward, but also have risen to up to 300 feet above grade, thus increasing odor exposure to neighboring properties. At the same time, urban sprawl has created widespread situations where neighborhoods and waste handling facilities encroach upon each other, creating more potential for unwanted odor exposure. And, of course, in today’s world, negative information about odor flare-ups spreads quickly thanks to social media and the 24-hour news cycle.

All of these factors combined have created an environment where there is significantly more pressure on waste handling facility operators to mitigate and reduce the odors emitted from their facilities. Today, if a waste handling facility is affecting neighbors, the negative response is likely to be rapid and, in some cases, severe. There are widespread reports of regulatory actions and lawsuits being levied against waste handling facilities.

With all this being said, as the world of waste handling changes, so too must the odor control practices employed by waste handling companies. However unrealistic it may be for the public to expect landfills to emit no odors detectable by their neighbors, it is now incumbent upon facility operators to implement solutions that help reduce odors and thereby reducing the risk of negative reactions from neighbors.

What are the best practices for odor management in this new era? Ask any landfill operator and they will tell you that even when adhering to strict operating plans and permit rules, odor control can be a challenge. Thankfully, there are some useful tips and tricks that the savvy operator can use to improve their facility’s day-to-day odor challenges.

General Tips for Odor Control
• Encourage your operators to stay ahead of the odor problem. Once odor complaints start rolling in, it is tougher to deal with the problem because the issue is already public. By using preventative measures, you stand a better chance than when you use reactive measures.
• Do frequent and honest self-reporting when implementing an odor mitigation plan. This means checking on the success or failure of your odor mitigation measures daily and determining if you need to adjust your strategy.
• Be honest about your operations and evaluations regarding any odors present on or offsite. Without honest evaluations, mitigating potential odors is difficult. Oftentimes, local managers do not want to admit they have odors and sometimes their olfactory senses are immune to it so they cannot detect odors.
• Ensure a weather station is working every day and wind speed and direction is recorded every day of the month. This information is critical when doing an investigation resulting from a complaint.
• Outline a written odor mitigation plan and be specific about that plan. Vague plans lead to vague outcomes.
• Odor surveys should be done before, during and after operating hours as conditions change operationally as well as climatically. These surveys must be documented manually or used within an app. Barometric pressure dropping at night and early morning can carry odors further offsite; therefore, surveys are recommended to be done before and after normal operations.
• Like water sprayed directly at the source of a fire, controlling odor is most successful when odor control solutions are deployed as close to the source of the odor as possible.
• Direct application of odor control products to odorous waste or areas is effective if you use a product that eliminates odor molecules. Masking agents, encapsulators and neutralizers do not work.
• Odor molecules stick to everything and often, empty trailers (such as transfer trailers and sludge trailers) can actually smell worse than full trailers. Trailers should be washed out weekly with a product that not only cleans, but also eliminates odors. During daily operations, a simply installed spray bar can reduce the odor impact to the community when trucks leave empty.
• If you have potential on or offsite odors and you are unclear what to do, raise your hand and ask for help. There are solutions for all types of potential odors.

Working Face
• Contained, controlled, tight working faces managed throughout the day to keep their size in check helps reduce odor throughout the day.
• If operations are geographically near sensitive receptors like a neighborhood or school, multiple layers of control are sometimes needed. Similar to litter control, a series of odor controls work better than just relying on one.
1. First control system is at the source, through direct application or upwind so the product can cascade over the source and impact the air. An example of this could be to install a misting system on litter fencing placed upwind of the working face. The system should have quick disconnects so they could be easily relocated. A mobile power source and pump along with a holding tank seems to be the most effective way to deliver odor control products in remote locations.
In lieu of litter fencing, bat wings, air cannons or T-posts with nozzles on them are sometimes used for intermediate control systems.
2. Second layer of defense would be downwind of the odor source but not too far from it so as to be effective. An example of this could be to install a misting system on the litter fencing located downwind from the working face.
3. Third layer of controls would be a perimeter system located at or near the property boundary between the working face and the neighbors.
This layer must be placed at the correct height interval to be effective. Establishing airflow patterns is critical in determining the correct nozzle spacing and height to effectively combat fugitive odors from escaping the site.
In instances where this third layer is visible to neighbors, the ability for the neighbor to see odor control misting can have a huge impact on their decision to file an odor complaint. (Odor complaints are commonly reported based on perception, not actual odor detection.)
• Other useful odor control devices include large fan misting systems placed near the working face located so the mist eliminates odorous gases.
• Another effective method is spraying the working face (with a water truck) at the end of the day before deploying the daily cover to eliminate odor molecules and prevent odor complaints throughout the night.
• Upon receipt of odorous waste such as wastewater sludge or industrial waste, directly apply a product to eliminate the odors prior to covering or burying.

Solidification Operations
• Mixing pits should install a perimeter misting system
• Adding certain chemicals may assist in odor reduction
• In small operations, a drum top mister may work

Landfill GCCS-Gas Collection and Control Systems
• Installation or drilling of new gas collection wells
• Trenching lateral lines between wells and to the header
• Gas well fields
• Intermediate cover with little to no well coverage
• Flare compounds
• Occasional odors can be treated with a water truck applied odor control product
• More frequent occurrences can be managed by portable or permanent odor control systems

Evaporation or Leachate Ponds
• Prevent anaerobic conditions by aeration
• Odor control product through perimeter misting
• Appropriate chemical addition to the pond

Leachate Tank Storage
• Odor control product through perimeter misting
• Appropriate chemical addition to the tanks
• Apply odor control product to all leaks/spills

Special Waste Tips
• Industrial waste from manufacturing or petrochemical plants or sludge from municipal plants sometimes contain nuisance odors like ammonia, mercaptans and strong VOCs.
• Direct application of product to a load of special waste has proven to be a very effective way to manage odorous waste. Using a product that can eliminate odor molecules can help a landfill manage waste that they ordinarily could not.
Waste companies many times have to reject odorous special waste because managing it has become problematic.
• A water truck application for large volumes or a portable, handheld sprayer can easily manage smaller volumes. Regardless of the site’s equipment capabilities, there is a solution.

Compost Operations
• Compost operations experience issues with odorous windrows, tipping pads, grinding equipment and runoff basins.

• Odors are generated when turning the windrows. Direct application to the windrows immediately after turning can provide days of sustained odor control.
• If the operation resides next to sensitive receptors, a perimeter system would help prevent any impact to the community.

Transfer Station Operations

• If the Transfer station operation is located near sensitive receptors, it should have a high-pressure misting system installed to prevent impact to the neighbors.
• The system should include coverage for the following areas:

• The doors should have misting down the sides and across the top to treat the air leaving the building
• A misting system should be installed over the tipping floor. The system should run at all times when trash is on the tipping floor
• Main doors throughout the facility should remain closed as much as possible
• Any roof vents or other locations where odors can escape should be covered with odor control misting
• Misting over the truck during loading, as well as staging and tarping areas is also very effective

• The transfer station floor and walls should be washed down weekly (or once a month at a minimum) with odor control products to eliminate the odor molecules and clean the walls and floor. This includes the tunnel and/or pit if applicable.

• The asphalt/concrete thoroughfares around the facility should be washed down regularly with an odor control product either in a street sweeper or pressure washer
• Trucks in and out of the facility carry odorous waste on their tires and undercarriage as well as leak leachate
• Trash in the tunnel and/or pit should be removed daily

• Automatic doors on each end of the tunnel/pit should be in place and remain closed before, after and during truck loading.
• While waiting to enter facility, trucks should be staged as far away from neighbors as possible.

Food Waste Processing
• Food waste should be confined to the smallest working area possible.

• Moisture content is not a concern
• Heavy misting as close to the waste as possible both overhead and on push wall

Direct application is effective for:

• Daily wash down of all surfaces and equipment with odor control product using a pressure washer

Odor control is required during offloading and loading

• Storage tank vents emit odors when filling and emptying liquids
• Tankers emit odors when loading liquids

Stay Ahead of Odor Challenges

Odor control is a fact of life in the modern waste handling industry. Thankfully, because of cutting edge technologies and a more widespread solid understanding of the best practices, effective odor control can be a reality at even the toughest waste handling site. Keep learning new tips and tricks every year and you will be sure to stay ahead of your odor challenges.
