treatment industry. In this work, sewage sludge samples were collected from the four main wastewater treatment plants in Nanchang City. Some significant physicochemical properties, such as pH, electrical... water (w/V)) using a digital pH meter (PHS-3C, China). Electrical conductivity (EC) was obtained through measuring the sludge extracts (1:5 solid/deionized water (w/V)) using a conductivity meter......
