New sludge treatment technology benefits environment & saves millions

Abstract

WASTEWATER The Water Wheel January/February 2003 A state-of-the-art sludge dewatering and drying plant, which cost R60 million and took two years to build, has recently come on line at the Cape Flats Wastewater Treatment Works, the largest sewage works in the Cape Metropolitan Area. The new technology not only reduces the amount of treated sludge requiring disposal, but also incorporates innovative recycling methods to reduce fuel consumption, and allows the sludge to be reused as an economically valuable product. The Cape Flats Wastewater Treatment Works, which lies alongside Zeekoevlei, close to the False Bay coastline, was commissioned in 1980. It was designed for a maximum incoming flow of 200 million litres of wastewater per day, and today it runs at about 80% capacity.
