Bateman Africa (Pty) Ltd supplied advanced belt press technology from Tenova to the Waterval Waste Water Treatment Works located south of Johannesburg for the East Rand Water Care Company (ERWAT).
Bateman Africa is the local empowerment arm of global mining, technology and equipment supply house, Tenova Mining & Minerals. The belt press technology was supplied to the wastewater treatment plant in collaboration with in-house technology partner, Tenova Bateman Technologies.
Bateman Africa was sub-contracted by the ERWAT via Botjheng Water (Pty) Ltd to supply four (3 duty +1 standby) Bellmer WinklePress belt presses for the treatment of various sludge types at the Waterval Waste Water Treatment Works.
The initial project scope definition required a combination of linear screens and belt presses to treat digested waste activated sludge, digested primary sludge and a combination of these sludges prior to disposal.
However, drawing on their combined extensive expertise, Bateman Africa and Bellmer proposed an innovative alternative solution where the linear screens’ functionality was replaced by extending the gravity dewatering section of the belt presses, resulting in reduced capital and infrastructure investment.
Designed and engineered as a collaborative effort by Bateman Africa and Bellmer, the process equipment is manufactured, assembled and factory tested in Germany, and exhibits high feed throughput, good sludge thickening, optimal dewatering, increased dry solids concentration and optimal filtrate values, without the need for upstream screening in the treatment circuit.
Bellmer’s pioneering developments include optimised roller configuration resulting in 1-3 % higher dry solids concentration as well as 5-10% lower flocculent consumption, high performance roller bearings with triple sealing, hydraulic belt alignment control and belt tensioning, unique scraper design, safety precision frames and high quality construction materials that lower maintenance costs and increase equipment life.
Bellmer Turbo Drains and WinklePress belt presses have been used successfully in southern Africa for many years in municipal wastewater treatment plants, as well as in the paper and fruit juice industries.
