Abstract/Artist Statement
Representatives of the City of Livermore’s (CoL) Water Reclamation Plant (WRP) are currently planning to install a fourth digester to accommodate the city’s rapid growth, but are seeking for a more cost efficient alternative. The proposed solution is to install a Gravity Thickener (GT) system to aid in the solids handling process. The advantage of the GT is the possible increase in the percent solids sent to the digesters, thus yielding a potentially greater efficiency out of the digesters. The GT tank must be of sufficient size to create the necessary hydraulic residence time, yet small enough to fit within the limited existing space at the WRP. The design of the GT system includes the pumping and piping network to transport the flows to and from the GT, structural design of the cast-in-place, reinforced concrete GT tank, cost analysis of the system replacement, and a site plan detailing the layout of the new pumping and piping systems. The deliverables for this project include a written report stating the design and cost estimations of the GT design, drawings of the new piping systems and GT tank, and an oral presentation.
