Development and performance evaluation of A 3-stage treatment system for domestic wastewater

This research project focuses on the development and performance tests of a 3-stage domestic wastewater treatment system which consists of; 1) Spiral-Framed Human Hair-Based Filter (HBF), 2) Biotower (BT), and 3) Pistia Stratiotes-Based Free Water Surface System (FWS) for removal of oil and grease (...
