The only membranes that concentrate valuable FOG and protein, reuse water, and recover anti-microbial chemicals.
Meat & Poultry wastewater, as well as process effluents derived from scald tanks, IOBWs, chillers, and other processing steps, are rich with residual fats, oils, greases (FOG) and proteins. These organic compounds increase the cost and complexity of wastewater management, as conventional treatment solutions:
- Do not repurpose the organics as valuable brown or yellow grease
- Do not recover water or unspent anti-microbial chemicals like PAA or chlorine
- Require coagulation and flocculation chemicals to remove organics before discharge, resulting in expensive and troublesome sludge disposal
- High potential to exceed discharge standards, resulting in surcharges and potential non-compliance risk
Membrane technologies are the ideal tools to capture and concentrate valuable organics without chemicals, purify water and unspent anti-microbial chemicals for reuse, and achieve the highest quality of treated effluent. Organic fouling has historically prohibited membranes from being usable in meat and poultry applications, but ZwitterCo’s membranes have unprecedented fouling resistance and upend historical restrictions on filtering organic-heavy streams, making new wastewater and effluent recycle solutions practical.
Fouling resistant membranes built for the FOG and protein in meat & poultry effluent
Chemical-free concentration of FOG and protein
- Upgrade FOG and protein to recoverable brown or yellow grease
- No in-line coagulant or flocculant chemical dosing required
Recycle water and PAA during production
- Recover water and unspent antimicrobial chemical before effluent reaches wastewater
- Ideal for IOBWs, chillers, and parts-chillers
Eliminate DAF chemistry and chemical-laden sludge disposal
- Convert your wastewater DAF to 'air-only' and use membranes to polish before discharge
- Avoid land application of chemically-laden DAF skimmings
Meet discharge requirements and eliminate surcharges
- Membranes remove >99% of FOG, TSS, and 70-90% of COD
- Highest quality treatment for dissolved organics before discharge

Chemical-free concentration of FOG and protein
Concentrate More. Dose Less.
During filtration, any compounds that are rejected by the membranes are captured and concentrated without relying on in-line coagulant or flocculant dosing. In a meat and poultry applications, ZwitterCo’s membranes can concentrate FOG and protein to 20x their initial concentration or higher. This has the two-fold benefit of:
Sanitary-style membrane system
- Successfully removing organics at a substantially lower operating cost, as no continuous chemical dosing is required. This can occur during production (i.e., at the IOBWs or chillers) to take organic load off of downstream wastewater operations or during wastewater treatment to ensure discharge compliance.
- Creation of a chemical-free FOG and protein concentrate stream that can be upgraded into valuable feedstocks. Once concentrated, the FOG and protein can be heated (so the fat, oil, and solids separate) and decanted to extract sellable yellow grease and brown grease byproduct streams.

Did you know?
Salmonella and E-Coli bacteria measure between 0.7 – 1.5 microns and 0.25 – 1.0 microns on their narrowest dimensions. SF membranes have 1 nanometer pores, meaning that they remove compounds 100x smaller than a bacteria cell.
Recycle water and PAA during production
Save chemistry. Reuse water.
Evolution SF membranes can remove >99% of FOG, protein, and bacteria out of process water while removing < 1% of unreacted anti-microbial chemicals like PAA or chlorine. This enables the capture and reuse of process water and residual anti-microbial chemistry before these streams reach the floor drains. Ideal processing steps include:
- Inside out bird washers (IOBW)
- Chillers
- Parts-chillers
- Other process steps with heavy water and anti-microbial chemical use
By continuously filtering the water in chillers, scald tanks, and other production steps that hold large volumes of water, processors can improve the efficacy of antimicrobial chemicals and minimize the accumulation of organic contaminants and bacteria. Preventing the accumulation of bacteria during production can help processors make enormous gains on their health and safety goals.
Eliminate DAF chemistry and chemical-laden sludge disposal
DAF without the dose.
When Expedition SF membranes polish DAF effluent, meat and poultry processors can eliminate the use of coagulation and flocculation chemistry in their DAF. The DAF can operate in “air-only” mode to remove fat, oil, and larger solids that naturally float or settle, letting the membranes remove contaminants larger than 1 nanometer.
The DAF float and membrane concentrate, which contain valuable fat, oil, and protein and are free of any chemicals, can be upgraded as a yellow or brown grease and converted to feed material. By finding a valuable outlet for these organics, plants can eliminate the disposal challenges that come with chemically-laden DAF sludge. This is especially important in jurisdictions that are increasing the scrutiny and restrictions around land-application of waste.

Meet discharge requirements and eliminate surcharges
Lower Surcharges. Cleaner Water.
ZwitterCo’s Expedition SF membranes remove suspended and dissolved contaminants larger than 1 nanometer. In meat and poultry wastewater treatment, this yields:
- >99% removal of FOG
- >99% removal of TSS and turbidity
- 70-90% removal of BOD / COD
- 50-70% removal of TKN
Depending on the initial concentration, filtering wastewater with Expedition SF will minimize or eliminate discharge surcharges related to organics. It also creates opportunities for non-potable reuse (i.e., truck & floor washing, meat screen flushing, etc.) or final wastewater polishing with reverse osmosis to remove chlorides and ammonia.
