Revolutionary Filtration for Profitable Sustainability

Aquora’s patented biomembrane filtration technology responds to the market need for low-cost and high throughput filtration of waste streams like wastewater or cow manure. Aquora’s technology has higher permeability and is easier to clean than existing approaches. OPEX and CAPEX reductions of 25%+ and 50%+ are expected, unlocking thousands of waste treatment projects with an addressable market estimated at $55B.

Critical Need for the Technology

Currently, most organic waste streams like food waste, human waste (i.e., wastewater sludge), and animal waste end up in landfills or lagoons, releasing significant greenhouse gas emissions (over 150 MMT CO2 eq/year in the U.S.). By talking to stakeholders in these fields, Aquora identified that waste separation to concentrate these streams is a key technological barrier that often becomes cost prohibitive for developers and owners. As public and private sector incentives or mandates continue to drive waste processing for recovery of valuable resources like energy and fertilizer, efficient and scalable separation technologies will be critical to make projects financeable. Aquora’s focus is on filling this gap, with an initial technology application of cow manure, a waste stream that is particularly challenging to filter.

Supplemental Need for the Technology

Aquora’s technology is an enabler for increasing on-site production of renewable energy, bio-based fertilizer, and reusable water. Fossil fuel-derived energy and fertilizer use can thus be offset, and local water sources can be maintained at sustainable levels.


  • Micro- and ultra-filtration membranes – These are not fit-for-purpose for processing most waste streams, which results in high OPEX and CAPEX due to severe fouling.
  • Mechanical thickeners – Centrifuges, screw presses, filter presses, and rotary drum thickeners can separate solids from liquids at varying levels of efficacy but at high CAPEX and/or OPEX due to large footprints and high use of chemicals and energy.

Potential Markets

Target waste/wastewater processing markets include:

  • Animal Manure (Dairy Farms, Hog Farms, Poultry Farms)
  • Industrial/Commercial Producers (Dairy, Beverage, Food, Pulp and Paper, Oil and Gas)
  • Municipal (Wastewater, Sludge, Food Waste)
  • Aquaculture

Non-waste processing markets include:

  • Treatment of emerging contaminants
  • Industrial Fermentation (biopharma, bioplastics, bioacids)

Key Innovation

High-rate filtration and biological treatment is made possible via intentional management of filtering biofilms that are developed on Aquora-designed support structures.
