Two-Step Reverse Osmosis Removes PFAS + PFOA

We recently completed testing with our Two-Step Reverse Osmosis system to demonstrate it can remove PFAS and PFOS from landfill leachate.  Here’s some background on the issue:

  • Per- and polyfluoroalkyl substances (PFAS) is a class of man-made chemical compounds that have been manufactured since the 1940’s.
  • PFOS and PFOA are two of the most widely known and studied PFAS compounds.
  • Due to their unique chemistry, they don’t break down in the environment, they bioaccumulate in higher organisms, and are difficult to remediate.
  • These chemicals were widely used in Teflon cookware, fabric protectants (e.g., Scotchguard), consumer packaging, fume suppressants at chrome plating shops, and as Aqueous Film Forming Foam (AFFF) for military and commercial aviation fields.

If you operate a landfill or have a source of process wastewater or groundwater contaminated with PFAS/PFOS, please call us today to learn how we can help! 

Our Two-Step Reverse Osmosis system removed all analyzed PFAS/PFOS chemicals to below the detection limits of the lab–see the data  table below:

Tackling a difficult laundry wastewater with UF and oxidation

When a client comes to us with a difficult wastewater, we get right to work identifying how best we can meet our client’s goals.  In this case, our customer had a laundry wastewater laden with ink and volatile organics. We used our stainless steel ultrafiltration to remove suspended solids and most of the color, then developed a unique oxidative approach to reduce the VOCs and further reduce the color.  Give us a call today to learn more about how we can help tackle your wastewater project!

“ACRE AgTech’s Newest Client Extracts Drinking Water from Manure”

For Immediate Release

ACRE AgTech welcomed Digested Organics LLC as a new client on May 15, 2017.  Digested Organics provides the agribusiness sector with sustainable waste management, alternative energy, and water reclamation solutions.  ACRE AgTech will use its resources to connect Digested Organics with agricultural and food processing operations that can benefit from their product line.

Digested Organics, an Ann Arbor based company, was founded in 2013 with the goal of improving the way society manages organic waste.  Simply put, their system can take all different kinds of organic waste— manure, vegetable scraps, beverage waste—and digest it into a fiber component, a nutrient component, and a reusable water component.  Initially targeting food waste from grocery stores and food processors as well as solids from municipal wastewater treatment systems, owner Bobby Levine soon saw the tremendous opportunity to help dairy and swine operations manage their manure and nutrients more effectively.

With 425,000 dairy cows and 2,000 swine farms in the State of Michigan, Levine began looking for ways to connect with those producers and reached out to ACRE AgTech for assistance.

ACRE’s Business Development Manager, Doug Huesdash, got to know Levine, his team, and their products in order to determine how ACRE’s services could benefit their organization.  It soon became clear that this would be a mutually beneficial relationship.  Levine commented “The ACRE team has been responsive to our needs before and since becoming a client.  They helped us secure a Michigan based sales representative almost immediately as well as several new customer contacts.  We value the connections and business expertise they have and look forward to continuing to work with ACRE to reach our goals.”  ACRE will continue working alongside Levine and his team to help them achieve their business goals while helping producers and food processors solve their waste and nutrient management issues.

Digested Organics has successfully installed their technology onsite at Majestic Crossing Dairy, a dairy farm in Wisconsin.  As a result of using Digested Organics’ technology on their farm, Majestic Dairy is able to process their 20,000 gallons of manure per day into clean water for farm use and surface water discharge, while at the same time harvesting energy through biogas generation.  The water that is produced from the manure is so clean that Majestic Dairy has obtained a surface water discharge permit from the DNR, a permit that has stringent requirements.

Digested Organics will be onsite at Michigan State University’s Anaerobic Digestion Research and Education Center through June 23 demonstrating how their technology functions by running test samples from food processors, farmers with manure management issues, and anyone with wastewater challenges.  For more information about Digested Organics LLC or if you are interested in providing a sample, please contact Dan Morton, their sales representative, at 616-437-3294 or visit their website at www.digestedorganics.com.

ACRE AgTech, formerly the Great Lakes Ag-Tech Business Incubator, has been providing connections and resources to agtech entrepreneurs in Ottawa County and across Michigan since December, 2014.  For more information about ACRE AgTech, please visit our website, www.acreagtech.com, or contact us at 616994-4745 or info@acreagtech.com.

Digested Organics completes landfill leachate trial

In addition to providing farms with cutting-edge technology to reclaim water, produce organic-certifiable fertilizers, and reduce manure handling costs, Digested Organics recently complete a trial with landfill leachate.  For landfills that are currently hauling leachate and experiencing high costs for disposal, our ultrafiltration platform can provide a robust and cost-effective solution to reduce suspended solids, BOD and COD, color/turbidity, and metals.  Download a more thorough testing report here.
