SOW 1.1.Description of the SERVICE

SCOPE

Tender for the supply and delivery of dewatering belts for belt filter presses for the City of Tshwane (CoT): as and when required: 3-year period.

BACKGROUND

The belt filter presses are used at various Waste Water Treatment Works (WWTW) to dewater sewage sludge from a solids consistency of 2% to 18% solids. Feed streams to the dewatering plants comprise anaerobically and aerobically digested sludge. Regular operational wear and tear, misalignment, clogging and tearing through introduction of foreign objects leads to a decline in process performance. This requires that the dewatering belts be replaced to achieve the same level of function.

3.DELIVERY ADDRESS

3.1 The belts must be delivered at the Daspoort WWTW Workshop store at, Bosman Street Extension, Pretoria.

3.2 Delivery shall occur at least 5 days after an order has been placed with the supplier.
