Development of the Technology for Bioconversion of Waste Activated Sludge From an Urban Wastewater Treatment Plant

Abstract

Pilot tests of the composting of waste activated sludge in an urban wastewater treatment plant with a consortium of thermophilic and thermotolerant bacteria has been carried out. The most effective was the bioconversion of activated sludge together with pine sawdust in a ratio of 1:1 or 1:2 using forced aeration of the mixture (0.35 m3/min).
