Hydrothermal Processes Applied to Sludge Reduction
Conventional Activated Sludge (CAS) systems have been widely implemented to treat wastewater. CAS systems produce huge amounts of waste sludge and its subsequent treatment represents up to 65 % of the operational costs of Waste Water Treatment Plants. The final disposal of sludge is usually …

The Biological Sludge Reduction by anaerobic/aerobic cycling
An activated sludge system that incorporates a sidestream anaerobic bioreactor, called the Cannibal process, was the focus of this study. A prior study of this process (Novak et al., 2007) found that this system generated about 60% less solids than conventional activated sludge without any negative …

An Investigation into the Mechanisms of Sludge Reduction Technologies
… method for reducing and stabilizing waste sludge from biological wastewater treatment for over a century; however, as sludge volumes and disposal costs increase, there has been a desire to develop various methods for reducing the volume of sludge to be treated, improving the performance of …

Performance and Mechanisms of Excess Sludge Reduction in the Cannibal™ Process
… study the performance and mechanisms of excess sludge reduction in the activated sludge that incorporates the Cannibal™ Process, laboratory activated sludge systems incorporating an anaerobic bioreactor into the sludge recycle stream were operated. In this study, the solids production in the …

Improving Anaerobic Digestion of Sewage Sludge Using Free Ammonia Pretreatment
A massive amount of sewage sludge is produced in the primary sedimentation (primary sludge) and wastewater treatment process (secondary sludge) in wastewater treatment plants (WWTPs) adding a heavy economic burden for WWTPs for their disposals. Anaerobic digestion (AD) for sewage sludge treatment …

Advanced Technologies for Resource Recovery and Contaminants Removal from Landfill Leachate
Landfill leachate contains valuable, recoverable organics, water, and nutrients. This project investigated leachate treatment and resource recovery from landfill leachates by innovative methods such as forward osmosis (FO), bioelectrochemical systems (BES), and advanced oxidation. In this study, a …
