Filtering Thin Stillage Beats Evaporation


Are you evaporating thin stillage? We can filter it instead at a fraction of the cost! Our stainless steel ultrafilter recovered ~75% of this thin stillage as a clarified filtrate with no suspended solids and significantly reduced nutrient content.

Key benefits:

  • UF permeate is ideal to reuse as backset since it contains no oils, no bacteria, and fewer volatile acids
  • Increases the amount of thin stillage usable as backset
  • UF concentrate is a higher solids slurry for incorporation into DDGS and reduces energy required for evaporation
  • May increase efficiency of corn oil recovery by reducing oil recycled in raw thin stillage to fermenters

UF Cleans Up Biodiesel Wastewater

We recently demonstrated how our stainless steel ultrafilter could process oil-washing wastewater rich in FOG from a biodiesel plant. The UF removes all suspended solids, FOG, and makes a filtrate that the plant can reuse to wash the next batch of raw oil. Our UF can also be an effective solution before onsite wastewater treatment or sewer discharge since it removes a large fraction of the BOD/COD. The UF concentrate is a high solids slurry (15-20% TS) that can be sold as an animal feed ingredient.

Digested Organics Awarded Grant for Manure Ultrafiltration in Vermont Phosphorus Innovation Challenge

Digested Organics was recently awarded a $45,000 grant to study manure and digestate ultrafiltration in Vermont as part of the Vermont Phosphorus Innovation Challenge (VPIC). We will be deploying a mobile pilot-scale ultrafiltration system to show how we can concentrate the phosphorus in dairy manure (or digested manure) into about 20% of the initial volume, thereby making it possible to transport to nearby composting operations for creation of value-added soil amendments that can be exported from the watershed. For more information, please see this presentation and check back here soon for more updates.

A video of the recent press conference is available via Facebook or can be viewed here:

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!
