5) The town of Camp Verde has been directed to upgrade its primary Wastewater Treatment Plant (WWTP) to a secondary plant that can meet an effluent standard of 25 mg/L BOD5 and 30 mg/L suspended solids. They have selected a completely mixed activated sludge system for the upgrade. The existing primary treatment plant has a flow rate of 0.029 m³/s. The effluent from the primary tank has a BOD5 of 240 mg/L. Using the following assumptions, estimate the required volume of the aeration tank. 1. BOD; of the effluent suspended solids is 70% of the allowable suspended solids concentration. 2. Growth constants values are estimated to be: K=100 mg/L BOD5; ka = 0.025 d-1; μm = 10 d-1; Y=0.8 mg VSS/mg BOD5 removed. 3. The design MLVSS is 3000 mg/L
A municipal wastewater flow of 1,000 m³/d contains 400 mg/L BOD5 and is treated to be in a trickling filter. The filter will use a plastic filter medium with a specific surface area of 200 m³/m² and will operate with a recirculation ratio of 100% and a hydraulic loading of 25 m³/m² -d. Based on a typical volumetric loading of 0.6 kg BOD5/m³-d, what volume (m³) of plastic media would be required?
a) A wastewater treatment plant consists of primary treatment followed by an activated-sludge secondary system. The plant processes 7000 m3/d of wastewater with 180 mg/L of BOD5 and 150 mg/L of suspended solids. The primary sludge contains 500 kg of dry solids per day with 4.5% solids content. The plant produces 760 kg of total sludge (primary and secondary) per day. Assume 30% removal efficiency of the primary clarifier and F/M ratio of 0.2 for the aeration tank. b) The thickened sludge from problem a) is to be digested in a standard-rate mesophilic anaerobic digester (MAD). The sludge has 68% organic content, and approximately 60% of the organic fraction is digested after a 30-d period. The digested sludge has a solids content of 6% and is stored for a period of 90 d. Calculate the volume of the standard-rate digester
Determine the dimensions of a high rate trickling filter for the following data: (ii) Recirculation ratio = 1.5 (iv) BOD removed in primary tank = 25%. (i) Sewage flow = 3.0 MLD (iii) BOD of raw sewage = 250 mg/L (v) Final effluent BOD desired = 30 mg/L By what % the diameter of the filter will have to be modified if it is to be designed as a standard rate trickling filter for the above requirement.
A trickling filter plant treats 1500 m³/day of sewage with a BOD, of 220 mg/l and a suspended solid concentration of 250 mg/l. Estimate the total solid production assuming that primary clarification removes 30% of BOD and 60% of influent solids. Take the solid production in the trickling filter at 0.5 kg per kg of the applied BOD.

A treatment plant treats water at an average daily flowrate of 2.7 m3/s. The water is chlorinated before it flows into a 15000 m3 reservoir. The water flowing into the reservoir has a chlorine concentration of 3 mg/L. Chlorine decays at a rate of 0.24 h-1. Assume the reservoir is well-mixed and the system is at steady-state condition. (a) Determine the chlorine concentration at the discharge point of the reservoir. (b) The treated water flows from the reservoir into a transmission main. The pipe carrying the water has a diameter of 2 m and flows full. In the transmission main, chlorine decays at a rate of 0.19 h-1. Determine the concentration of chlorine 2 km from the treatment plant.
