Distributed Low-Energy Wastewater Treatment (DLEWT) for Fuel Generation and Water Reuse
Abstract
The Distributed Low-Energy Wastewater Treatment (D-LEWT) project aimed to demonstrate and validate a novel decentralized energy-efficient anaerobic wastewater treatment technology. D-LEWT is a distributed low-energy wastewater treatment system that enables water reuse and converts black water contaminants into harvestable fuels, hydrogen (H2) and methane (CH4) gas, for energy generation. D-LEWT integrates an anaerobic membrane bioreactor (AnMBR) process with clinoptilolite ion exchange and ammonia electrolysis for the efficient removal of organics, particulates, and ammonia. Methane, a byproduct of the anaerobic reaction, and hydrogen, from ammonia electrolysis, can be used to generate electricity to offset system energy requirements. Additionally, the availability of treated water for reuse will decrease installation water usage.
