Description
Summary:Surakarta City or Solo City is one of the cities in Central Java Province with the highest population density. Wastewater management in Surakarta City is carried out by the Regional Public Drinking Water Company (PDAM) of Surakarta City by providing several wastewater treatment facilities such as the Semanggi WWTP, which is the largest WWTP in Surakarta City with a treatment capacity of 60 liters/second. Along with the increasing population, the wastewater that will be treated by the Semanggi WWTP will also increase. The redesign of the Semanggi WWTP aims to increase the capacity and efficiency of treatment, so that the Semanggi WWTP can treat wastewater optimally. The methodology used in this redesign is literature study, problem identification, primary and secondary data collection, data processing and analysis, system selection, technical design, preparation of supporting documents, and analysis of non-technical aspects. Based on literature studies, the processing efficiency of the Clover WWTP ranges from 30% to 75% with several main problems in the form of flooding and non-fulfillment of design criteria for processing units, especially biological processing units. These problems can be solved by replacing, adding, and/or engineering the processing unit. The selection of alternative processing unit technologies is carried out using a selection matrix based on the processing efficiency of each technology. In addition, the selection of alternative technologies is also based on several things such as land needs, costs, ease of use, and environmental impact. Based on these considerations, the configuration of the Semanggi WWTP treatment unit consists of a bar screen, grit chamber, equalization basin, MBBR, sedimentation basin, chlorination basin, and sludge treatment in the form of gravity belt thickener. The redesign of the Semanggi WWTP will be carried out in 2 stages, with processing capacities at each stage of 0.093 m3/second and 0.123 m3/second. The construction of the Semanggi WWTP will cost Rp15,947,776,586, with operational costs of Rp150,801,588 per month in the first phase and Rp157,354,569 per month in the final phase.
