Abstract:
1. A multistage anaerobic digester for treatment of wastewater including complex organic polymers, comprising: a pre-treatment process by a Centrifugal Wastewater Filtration System (CWFS) having an output substrate of Energy Latent Organics that are within a 0.2-30 micron range; a hydrolysis stage converting the complex organic polymers, including said output substrate, received at an inlet to solubilized monomers at an outlet; an acidogenesis stage, coupled to said outlet of said hydrolysis stage, converting said solubilized monomers into intermediate products at an outlet of said acidogenesis stage; an acetogenesis stage, coupled to said outlet of said acidogenesis stage, converting said intermediate products into simple molecules at an outlet of said acetogenesis stage; and a methanogenesis stage, coupled to said outlet of said acidogenesis stage, converting said simple molecules to an end product, said end product including a quantity of methane and a quantity of carbon dioxide; wherein each said stage includes a self-contained compartment containing one or more angled augers, coated with immobilized enzymes, configured to transport the substrate from stage to stage.
