A rectangular horizontal-flow sedimentation basin in a conventional water treatment plant has been designed to treat a flow of 50,000 m3 /day. It has a length = 80 m, width = 20 m, and depth = 3.6 m. For this problem, assume temperature = 20 °C (density of water = 103 kg/m3 and viscosity = 10-3 kg/m·s) and laminar flow. a. What is the hydraulic detention time? Does this meet the typical criteria for this type of sedimentation basin? b....

You have been retained to design a wastewater treatment plant using a conventional activated sludge process for a town of 40,000 people. The industrial flow contribution to the sewer system is 300,000 gallons per day. Effluent discharge standards require effluent BOD5 and total suspended solids concentration of <10 mg/l. Assume the following design criteria are applicable: Domestic sewage flow = 100 gal/cap/day (including I/I) BOD loading = 0.18 lbs/cap/day TSS loading = 0.20 lbs/cap/day BOD removal in primary = 33%...

The town of Camp Verde has been directed to upgrade its primary Waste Water 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...

A surface water treatment plant treats a 6,000 L/day flow with alum coagulation, identified by the following stoichiometric reaction: Al2(SO4)3 ∙ 14 H2O + 6HCO3- ↔ 2Al(OH)3 (s) + 6 CO2 + 14 H2O + 3 SO42- Molecular weights (g/mol): Al2(SO4)3 ∙ 14 H2O  =   594.5 HCO3-  =  61 Al(OH)3  =  78 SO42-  =  96.1 Jar tests indicate that 55 mg/L of alum are required to optimally treat the surface water. Removal of approximately 20.2 mg/L of suspended solids also occurs in this sytem. Estimate the mass of...

Problem 3 (15 pts) A vertical turbine flocculator has been chosen for a new water treatment plant. The plant is in a dense urban area and space constraints mean that an area of 40 m2 per basin is available for three trains consisting of three stages. The basins should be cubical and of equal volume, and the following velocity gradients are needed for each stage: 45 s-1 in the first, 20 s-1 in the second, and 10 s-1 in the...
