EVALUATION OF UNIVERSITI TEKNOLOGI PETRONAS SEWAGE TREATMENT PLANT PERFORMANCE AND ITS DESIGN

This report is a study for evaluation the performance of each treatment process in Universiti Teknologi PETRONAS Sewage Treatment Plant. University Technology PETRONAS Sewage Treatment Plant (UTP's STP) is a treatment plant that used an Extended Aeration Activated Sludge (EEAS). The sewage treatment plant is capable treat effluent to a standard A which is 20 mg/Ll of BOD and 50 mg/L of suspended solids. A hydraulic loading off 225 L/pe/d and an organic loading off 55 g/pe/d and sludge storage of 40 days at 4% of solid were considered for design. The design basis flow rate for this plant is about 5,175.00 m3/d or 23,000 population equivalent. This sewage treatment plant consists of inlet chamber, grit and grease chamber, distribution chamber, anoxic zone, aeration tank, clarifier and chlorination tank. At the beginning stage, the problems are identified on the various parameters such like biochemical oxygen demand (BOD) and total suspended solids (TSS). Samples from UTP's STP will be taken frequently to analyze the wastewater in the laboratory. At the end, this project will help the properties management and maintenance department (PMMD) a better operating system of the STP and also provide a recommendation of upgrading.
