Sustainable Wastewater Treatment and Resource Recovery Solutions

Technologies

VaSA couples vacuum stripping and acid absorption to strip ammonia out of ammonia-rich wastewater (e.g., anaerobic digestate, landfill leachate, animal manure, and source-separated urine) to form granular ammonium salts, sellable nitrogen fertilizers and reagent-grade chemicals, while enhancing solids solubilization for increased biogas production

While phosphate is removed from wastewater to achieve management and permit compliance goals, struvite is recovered as a slow-release fertilizer. Unlike chemical-based technologies to recover struvite for traditional farming, STROP produces struvite as a natural fertilizer by supplementing magnesium and raising pH with two mineral-based products, making struvite potentially acceptable for organic production.
