Applied Envrionmental Technology is developing a passive biofiltration process to enhance nitrogen and sulfur removal from onsite sanitation water. This system is a multi-chamber treatment process that removes nitrogen from wastewater at a high percentage. The system features passive operation, low life cycle cost and resilient performance. It applies anaerobic biological treatment in a multi-chamber upflow solids blanket bioreactor. The system removes organics and recovers energy. Under its Phase I reward, the company will experimentally validate two prototype designs and provide a scale-up basis for Phase II.
