Laboratory Demonstration and Preliminary Techno-Economic Analysis of an Onsite Wastewater Treatment System.

ABSTRACT: Providing safe and reliable sanitation services to the billions of people currently lacking them will require a multiplicity of approaches. Improving onsite wastewater treatment to standards enabling water reuse would reduce the need to transport waste and fresh water over long distances. Here, we describe a compact, automated system designed to treat the liquid fraction of blackwater for onsite water reuse that combines cross-flow ultrafiltration, activated carbon, and electrochemical oxidation. In laboratory testing, the system consistently produces effluent with 6 ≤ pH ≤ 9, total suspended solids (TSS) < 30 mg L^-1, and chemical oxygen demand (COD) < 150 mg L^-1. These effluent parameters were achieved across a wide range of values for influent TSS (61-820 mg L^-
