Nutrients and Biosolids Management
Biosolids Management That Creates Value. Wastewater biosolids have historically been considered a waste stream to be discarded into landfills—making biosolids management a significant cost and liability in the wastewater treatment industry. But to Anaergia, biosolids management means creating value. With our integrated nutrient recovery technologies, your facility can maximize the value of biosolids by extracting energy and creating valuable organic fertilizers. Our solutions recover up to 20% more renewable energy, extract nutrients to create valuable fertilizer products using our proprietary ammonia removal technology, and achieve Class A biosolids. What’s more, our solutions do this while reducing biosolids volumes by up to 80%, minimizing disposal costs, and cleaning liquid effluent streams.
Anaergia’s proprietary dewatering technology dewaters digestate in preparation for downstream value extraction or use. Our slow speed and low energy-load equipment is designed to create long duty cycles and be virtually maintenance-free.
Our unique AMR™ ammonia recovery technology uses waste heat to extract more than 90% of the nitrogen, potassium, and phosphorus from high strength waste streams such as filtrate from dewatering.
And our advanced digestate drying systems further reduce moisture content from dewatered biosolids without producing dust. Our equipment can operate using available on-site low-grade waste heat.
With our PyroSys™ pyrolysis system, dewatered sludge can be converted into Class A-EQ pyrolyzed biosolids. The fully-automated process reduces dewatered biosolids volumes by 10x, and even eliminates contaminants of emerging concern (CECs), including PFAS and PFOA.
Extracted water can be treated with Fibreplate™, a next-generation hybrid membrane bioreactor for filtrate and wastewater recycling.
