Abstract

The purpose of this study was to determine the effect of an aerobic bioaugmentation process on the activated sludge treatment of potato wastewater. Parameters investigated included types of live liquid microorganisms (LLMO), aeration time, LLMO dosage and wastewater strength. Types of LLMO included S-l, G-l, E-l, N-l and NEW-1. TOC (total organic carbon) and MLVSS (mixed liquor volatile suspended solids) were determined during the bench scale aerobic batch activated sludge reactor study. Results showed that bioaugmentation with LLMO addition had an important effect on both TOC removal efficiency and sludge reduction. S-l LLMO was the most effective, while N-l or E-l was the least effective LLMO in the batch activated sludge treatment of potato wastewater. The best TOC removal efficiency obtained was 98%, while the best sludge reduction obtained was 67% in terms of initial MLVSS concentration. © 1994, Taylor & Francis Group, LLC. All rights reserved.
