Evaluation and Installation of Sludge Dewatering Equipment at Lower Level of Sludge Dewatering Complex II (CS-1290 / PC-750)

Tucker, Young, Jackson, Tull, Inc. (TYJT) provided study, design, and construction services for the removal of existing belt filter presses and installation of eight new centrifuges for dewatering of sludge on the Lower Level of Dewatering Complex II at the DWWTP with a total sludge dewatering capacity of 32,000 pounds of dry solids per hour (or 16 dry tons per hour). The project provided a complete new sludge dewatering system consisting of the centrifuges, sludge pumping, sludge mixing, polymer conditioning and sludge conveying , including both belt and screw-conveyors.

The study phase of the project included evaluation of alternative sludge dewatering by belt filter presses and centrifuges and selection of centrifuges for sludge dewatering. In addition, the scope and design criteria were established for all the associated systems and functional areas.

The Design Phase services included multi-disciplinary design and production of contract documents for mechanical, structural, HVAC, electrical, I&C, and architectural work.

The Construction Phase services included responding to contractor RFIs, shop drawing reviews, preparation of O&M manuals and SEMPS, punch list development, and start-up and training. The construction contract was part of the PC-744 scope of services (i.e., a Table-2 project).

Status of Project:
The project is complete and the facility has been in operation since May 2004.
