The wastewater is being conveyed through the piping system (gravity and force main) into the wastewater treatment plant. The engineering team in charge of the design is in the process of laying out the initial proposed dimensions for each of the components. Your job is to assist this initial design stage and help the team determining the dimensions for some of these infrastructures. The plant will consist of the following components: i. ii. iv. V. vi. vii. Mechanical bar screen - determine the channel size and the amount of debris to be removed. Grit removal system (done by others) Influent flow pump station (done by others) Primary Settling Tank - determine the size of two tanks operating simultaneously. Biological process - determine the best alternative between trickling filters and conventional activated sludge. Secondary Settling Tank (done by others). Disinfection System - determine the size of the chlorine contact tank the weight of chemical usage per day.
