ALL NEW FOULING-IMMUNE MEMBRANE TECHNOLOGY FOR
Manure Digestate
It’s time to upgrade your manure digestate management. ZwitterCo’s superfiltration (SF) membranes remove tough-to-treat compounds from digestate, allowing downstream reverse osmosis 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.

Manure Digestate Solutions
What Challenges Can ZwitterCo Technology Solve For You?
MaximizeNutrient Recovery
ZwitterCo SF membranes integrated into a filtration system enable the efficient concentration of nitrogen and phosphorus, which creates the opportunity for saleable product from those excess nutrients.
EnhanceWater Recovery
ZwitterCo SF membranes when used as pretreatment for RO, achieve water recovery rates of 60-90% in harsh digestate applications, significantly reducing the volume of digestate needing to be stored or hauled.
EnsureContinuous Operations
Fouling-immune ZwitterCo SF membranes ensure stable and efficient digestate treatment, reducing risk of unplanned downtime and supporting compliance with nutrient management plans.
Minimize Hauling& Costs
ZwitterCo superfiltration membranes assist in efficiently separating water from digestate, significantly reducing volume and cutting transportation costs by minimizing off-site hauling
SOLUTION #1
Maximize Nutrient Recovery
Integrating ZwitterCo SF membranes significantly enhances nutrient recovery by removing 99% of suspended solids and organic foulants, allowing downstream technologies like RO to run more efficiently.
- Patented zwitterionic membrane is immune to irreversible fouling
- 1nm pore size produces TSS free permeate
- Filters out unwanted materials before RO processing
- Ensures only desired nutrients are concentrated
SOLUTION #2
Enhance Water Recovery
By efficiently filtering digestate, ZwitterCo SF membranes – when used as pretreatment for RO – achieve water recovery rates of 60-90%.
This enables water reuse for animals and significantly reduces the volume of digestate requiring storage or hauling, lowering costs and environmental harm.
SOLUTION #3
Ensure Continuous Operations
Digestate management and treatment systems built with our SF membranes offer:
- Full performance recovery after mild maintenance wash
- Minimal downtime with scheduled CIP
- 2 – 3 year expected membrane life
Fouling-immune ZwitterCo SF membranes ensure stable and efficient digestate treatment, reducing risk of unplanned downtime and supporting compliance with nutrient management plans.
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.
Save on Hauling
Fully integrated solutions featuring SF membranes have shown to reduce digestate hauling by 50-70%
APPLICATION BRIEF
Total Re-Haul of Manure Digestate Treatment
Land spreading regulations are becoming stricter and as a result, large volumes of digestate need to be hauled off-site. This is both costly and carbon intensive.
ZwitterCo SF membranes enable an economical, reliable, and sustainable transition away from hauling and pave a path to the future of digestate management.
