Create Marketable Products from Biosolids and Eliminate Disposal Costs
Biosolids left over after anaerobic digestion have historically been considered a waste stream to be discarded, which equates to significant cost and liability. Maximizing resource recovery means extracting as much value as possible at every single stage. To Anaergia, biosolids are a significant opportunity for value creation.
Our integrated nutrient recovery and biosolids management solutions recover up to 20% more renewable energy, extract nutrients as valuable fertilizer products using our proprietary Ammonia removal technology, and achieve Class A biosolids all while reducing biosolids volumes by up to 80%, minimizing disposal costs, and cleaning liquid effluent streams.
Our Value Addition
- Increase renewable energy production by up to 20%.
- Produce valuable liquid fertilizer.
- Produce class A biosolids for disposal.
- Reduce ammonia concentrations in liquid effluent streams by 90%.
- Reduce biosolids disposal volumes up to 80%.
- Kill potential pathogens and produce a Class A biosolids product.
Our Offerings
- Dewatering: Our proprietary dewatering equipment is the ideal solution for dewatering digestate in preparation for downstream beneficial value extraction or use. The slow speed and low energy-load equipment is associated with long duty cycles and is virtually maintenance free
- Nutrient Recovery: Anaergia’s nutrient recovery solutions, including its proprietary AMR technology, extract over 90% of nitrogen, potassium, and phosphorus from high strength waste streams (such as filtrate from dewatering). Removing these constituents from effluent streams helps facilities meet effluent quality requirements and produces valuable fertilizer for sale
- Drying: Our advanced drying systems further reduce moisture content from dewatered biosolids without producing dust, and can do so using available on-site low-grade waste heat
- Pyrolysis: Dried biosolids contain significant energy and some moisture content which can be further extracted by applying heat in an oxygen-starved environment. This process not only further reduces mass, it also creates bio-oil which can be used to increase renewable energy production.
- Fibreplate Hybrid MBR for filtrate/wastewater recycling
