Abstract

This project is about to evaluate the performance of Universiti Teknologi Petronas Sewage Treatment Plant (UTP's STP) with the help of activated sludge wastewater treatment pilot plant The sewage treatment plant (UTP's STP) consists of inlet chamber, grit and grease chamber, distribution chamber, anoxic zone, aeration tank, clarifier and chlorination tank; and the activated sludge wastewater treatment pilot plant consist of feeder tank, aeration tank and a clarifier The main purpose of this project is to evaluate the performance of the secondary treatment process from UTP's STP consistingofan anoxic zone, aeration tank and a clarifierand evaluate the impact of chemical waste solution prior to treatment into the STP. A pilot plant with feeder tank, aeration tank and clarifier was used to stimulate the UTP's STP treatment process. The parameters that have been studied for this project is mixed liquor suspended solids (MLSS) or activated sludge, Total Suspended Solids (TSS) and Sludge VolumeIndex (SVT) or sludge settleability. Wastewater from UTP's STP was fed into the activated sludge wastewater treatment pilot plant once in a week. The flowrate and retention time measured from exact operation of UTP's STP was scaled down (1:6) in the pilot plant to stimulatethe process of UTP's STP into the activated sludge wastewater treatment pilot plant. The laboratory experiment was done in two different phases. For Sewage Treatment Plant, in the first phase, tests wereconducted before the oxidation pond wastewater was diverted to Sewage Treatment Plant and in the second phase, tests were conducted after the oxidation pond wastewater was diverted to Sewage Treatment Plant Result obtained showed, the effluent from STP for both phases was met the Environmental Quality Act (EQA), 1974 standard. Meanwhile, for pilot plant, in the first phase,tests were conductedunder the condition of no sludge recycle in activatedsludge and in the secondphase, tests were conducted under the condition of allowing sludge recycle in activated sludge addition with chemical waste solution discharge from Chemical Block 3 and 4. Result obtained showed, percentage of TSSremoval in the first phasewas91%and dropped to 36%in the second phase. These suggested that additionalofchemicalwaste gave an effect on the treatment plant operation. SVT results obtained showed, the settling quality of the pilot plant aerated mixed liquor was satisfied.
