Cyclic Activated Sludge Technology - Recent Operating Experienc

Cyclic activated sludge technology was selected for the Potsdam Wastewater Treatment Plant (90,000 p.e.). The cyclic activated sludge facility comprises four modules integrated into two circular basins. Construction was commenced in February 1998 with seeding of the plant for start up taking place in October 1998. Process performance has been met since Spring 1999 at 80-90 percent of design loa...

Incorporation of paper sludge in clay brick formulation: Ten years of industrial experience

Activated Sludge Treatment of Paper Mill Effluents

Introduction The pulp and paper industry is the second largest industrial water consumer in Europe with a usage of 35 m3/ton paper and a production of 85.2 M tons/year. Its effluents cause considerable damage to the receiving waters if discharged untreated since they have a high biochemical oxygen demand (BOD), chemical oxygen demand (COD) and contain chlorinated compounds, suspended solids (ma...

Production of technical grade phosphoric acid from incinerator sewage sludge ash (ISSA).

The recovery of phosphorus from sewage sludge ash samples obtained from 7 operating sludge incinerators in the UK using a sulfuric acid washing procedure to produce a technical grade phosphoric acid product has been investigated. The influences of reaction time, sulfuric acid concentration, liquid to solid ratio and source of ISSA on P recovery have been examined. The optimised conditions were ...
