Regarding inviting quotations for the preparation of a rate schedule for Screw Press and Screw Pump required for sludge dewatering at STP within the Pimpri Chinchwad Municipal Corporation.

Amount

Screw Press- Designing, Providing, Testing, Supplying, installing and commissioning of Sludge Dewatering Screw Press shall be designed to apply three functions into one unit, in which the three zones are conditioning zone, thickening zone and dewatering zone. sludge extrusion dewatering equipment by using the principle of screw extrusion, through the strong squeezing force generated by the change of screw diameter and screw pitch, and the tiny gap between the floating ring and the fixed ring, to realize solid-liquid separation. It shall be able to run continuously and automatically to dewater sludge up to 15% to 25% of outlet consistency. In the process of advance, with the gradual decrease of filtering gap and screw pitch, and the blocking effect of back pressure plate, a great internal pressure is generated leading the volume is constantly reduced, so as to achieve the purpose of full dewatering. Screw press shall be self-sufficient for its operations including conditioning, thickening dewatering & cleaning. External water shall be provided for cleaning (Specify the type of water required).
