Application of imaging techniques for monitoring flocs in activated sludge

Abstract

Activated sludge process is commonly used for purification of waste water. In this paper imaging techniques are used to monitor activated sludge flocs in waste water treatment plants (WWTPs). Monitoring the flocs includes study of floc morphology and quantification of flocs. This information can help in the prediction of abnormal events in WWTPs and may help in avoiding plant malfunction.
