FOULING-IMMUNE MEMBRANE TECHNOLOGY FOR
Food Waste Digestate
ZwitterCo’s superfiltration (SF) membranes remove tough-to-treat compounds from food waste digestate, allowing downstream polishing and nutrient recovery technologies to operate efficiently.
Edison Award
ZwitterCo superfiltration membranes received a Bronze award for innovation in the Water Treatment & Testing category at the 2024 Edison Awards.
This award highlights their impact on the meat and poultry industry, enabling > 99% removal of FOG and TSS.

Unlike biological treatment methods, direct filtration with ZwitterCo SF:
- Requires 1/4 the footprint
- Easily handles changes in feed conditions
- Concentrates complex organics that are challenging to break down biologically
Food Waste Digestate Solutions
What Challenges Can ZwitterCo Technology Solve For You?
Ensure ContinuousOperations
Fouling-immune ZwitterCo SF membranes ensure stable and efficient digestate treatment, reducing the risk of unplanned downtime to support the delivery of new feedstocks.
EnhanceWater Recovery
ZwitterCo SF membranes when used as pretreatment for RO efficiently filter digestate, boosting water recovery rates (60-90%) and significantly cutting down the volume of digestate needing storage.
ReduceFootprint
Direct filtration with ZwitterCo SF eliminates the need for large aeration tanks and the high OPEX associated with biological solutions.
Minimize Hauling& Costs
Filtration solutions using our superfiltration membranes cut food waste digestate volumes by up to 50-70%, directly reducing the volume and cost of hauling.
SOLUTION #1
Ensure Continuous Operations
In digestate applications, managing nutrient-rich water discharge requires strict regulatory compliance. Meeting discharge requirements, including NPDES regulations, can be challenging due to the presence of fats, oils, and grease (FOG) and frequent cleaning demands.
ZwitterCo membrane technology simplifies this process by:
- Effectively removing FOG
- Reducing cleaning frequency
This streamlines the path to regulatory compliance—saving both time and operational costs.
SOLUTION #2
Enhance Water Recovery
By efficiently filtering digestate, ZwitterCo SF membranes – when used as pretreatment for RO – facilitate water recovery rates ranging from 60-90%.
This enables water reuse internally and significantly reduces the volume of digestate requiring storage, lowering costs and environmental harm.
Water reuse, like landscape irrigation or other nearby demand centers, helps offset freshwater consumption to better preserve local water resources.
SOLUTION #3
Reduce Footprint
Direct filtration with ZwitterCo SF membranes offer a footprint friendly solution for operations tight on space.
These systems can be entirely fabricated offsite, reducing CAPEX and long onsite construction, and simplifying permitting for new urban biogas projects.
- High packing density
- No large aeration tanks
- Modular design to easily support expansions
Lower Your CI Score
Reduce GHG by minimizing hauling and reducing overall electrical consumption with ZwitterCo SF membranes
WATER PURIFICATION
ZwitterCo Reverse Osmosis
ZwitterCo has integrated our patented zwitterionic technology with proven commercial brackish water membranes to deliver a drop-in replacement RO membrane with unprecedented fouling resistance.
ZwitterCo RO after MBR, tubular membranes, or to replace existing RO offers:
- Up to 90% reduced cleaning frequency
- 2x element life due to easier and quicker cleaning
- Effective concentration of essential nutrients for recovery and reuse
SOLUTION #4
Minimize Hauling & Costs
ZwitterCo superfiltration membranes assist in efficiently separating water from digestate, significantly reducing its volume.
This concentration process minimizes the amount of material that needs to be hauled off-site, leading to lower transportation costs and fewer hauling trips.
Additionally, the recovered water can be reused within the operation, further enhancing sustainability and cost-efficiency.
