Superfiltration Membrane for Manure Digestate Management

Reduce Offsite Hauling

Reduce digestate volumes and transportation costs by 50-70% with ZwitterCo’s membrane-based solutions.

Recover & Concentrate Nutrients

Our membranes produce a concentrated organic fertilizer, allowing for easy selling or storage.

Improve Sustainability

Limit excess nutrient loading on soil, reuse water, and decrease carbon intensity scores.

Improve Permitting & Compliance

Maintain compliance with existing and tightening nutrient management regulations. Decrease conventional land application practices.

The Challenges with Manure Digestate

There are almost as many on-farm anaerobic digestion projects under construction in the United States today as have been built in the last ten years. And for good reason. The American Biogas Council reports that the United States is harnessing only 5% of the biogas potential of dairy, poultry, and swine farms.

Conversion of manure and farm residuals into biogas and renewable natural gas (RNG) creates value from the inherent energy in agricultural waste. Managing the liquid digestate, however, is a significant constraint in the permitting, cost-effectiveness, and overall sustainability of biogas development projects.

The ZwitterCo Superfiltration Solution

ZwitterCo’s superfiltration membranes were designed to process the toughest digestate streams, resolving disposal challenges and creating value from the leftover water and nutrients that remain beyond Renewable Natural Gas (RNG) production.

Sustainable digestate management and treatment systems built with our superfiltration membranes can help you reduce the costs and carbon intensity of operating your biogas facility. Implementing a membrane-based solution for digestate can reduce waste hauling and emissions from land application, unlock water reuse for irrigation or livestock, and enable the creation of organic fertilizer from recovered nutrients.

ZwitterCo Superfiltration

A Paradigm Shift in Membranes

Superfiltration membranes are a new separation class between ultrafiltration and nanofiltration. ZwitterCo superfiltration membranes deliver unprecedented fouling resistance, low energy requirements, wide pH tolerance, and the ability to be cleaned with chlorine.

Superfiltration membranes are designed for fractionating dissolved components, like capturing protein while passing inorganic molecules. Our membranes are engineered tightly enough to remove fats, oils, grease (FOG), and high-strength organics, providing ideal pre-treatment for reverse osmosis in wastewater.

The Benefits of ZwitterCo

Haul Less and Reduce Costs

Off-site hauling has been a part of the global digestate equation for decades, but it can be reduced or even eliminated.

Filtration solutions using our Superfiltration membranes can:

Cut manure digestate volumes by up to 70%
Directly reduce the volume and cost of hauling

And, when concentrated organic solids and nutrients can be stored in smaller volumes and repurposed as co-products throughout the year, advanced digestate treatment eliminates the waste disposal hassle.

Unlock New Revenue Streams

Filtration solutions that leverage our Superfiltration membranes can recover and concentrate nitrogen, phosphorus, and potassium (NPK) for use as organic fertilizer.

Concentrate can be stored over the winter and used or sold during ideal growing seasons. It’s a sustainable alternative to chemical-based fertilizers and a potential new revenue stream from what is otherwise a waste output.

Improve Sustainability & Carbon Intensity

Biogas facilities can achieve lower carbon intensity scores by more sustainably managing digestate, whether through reducing offsite waste hauling, preventing the overloading of nutrients on soil from land application, or achieving wastewater quality safe for discharge or reuse.

Reusing water for livestock watering or crop irrigation also helps offset freshwater consumption to better preserve local water resources.

Future Proof Your Operations

Achieve the greatest level of nutrient removal before discharge, ensuring:

Compliance with your nutrient management plan even as discharge standards and soil nutrient regulations become increasingly stringent.
Open the door to water reuse, supporting future water security in the face of rising water scarcity and utility costs.
