A water treatment plant is designed for a constant flow rate of 3 MGD. The flocculation system consists of three tanks, each having a water depth of 10 ft and an average hydraulic residence time (HRT) of 30 min. (a) Determine the dimension of each tank (i.e., width and length). (b) Determine whether the flow through velocity is acceptable. (c) The plant is planning to take one tank out of service for maintenance. Determine the increase in power requirement...

A water treatment plant has three identical horizontal shaft flocculation tanks. Each tank is composed of three stages with size of 4 m depth, 14.1 m length and 15 m width. G value of each stage is 40 s-1, 30 s-1 and 20 s-1. Mean water temperature is 15°C (μ = 1.139×10-3). What are the power requirements for flocculation stages in a single flocculation tank. And Is the flocculation tank in an efficient way? ( Plant's average flow rate of...

Design a set of activated sludge aeration tanks. The flow rate to treat is 5.6 MGD and the BOD concentration is 150 mg/L. The design solids concentration (X) at steady-state is 2,000 mg/l. The design MCRT is 7 days. The kinetic coefficients are as follows: K = 2 g BODg cells⋅d, Ks = 25 BOD/L, Kd = 0.06 day-1, Y = 0.5 g BODg cells⋅d. The influent ammonia concentration is 40 mg/l and nitrification is needed. It takes 1400 ft3of...

Your professional company is hired to perform a hydrologic-hydraulic study needed for the design of a new bridge. The 75-year historical data (annual maximum series) collected from a nearby station at a river was used to develop the statistical parameters. The expected project life of the bridge is 50 years. Following bridge safety regulations, the 500-year flood (based on annual maximum data series) is used for design purposes. The bridge construction will require five (5) years of work inside the...

A manufacturing machine supplier needs your help to design a hydraulic circuit for 2 cylinder output that operate in sequence, one after another. Please consider a minimal usage of components in your design. Explain the operation based on...

A radial flow hydraulic turbine whose design is based on a power specific speed,

A radial flow hydraulic turbine whose design is based on a power specific speed, Ωsp=1.707 is to produce 25 MW from a total head, HE=25 m. The overall turbine efficiency ηo=0.92, the mechanical efficiency is 0.985, and the loss in head in the nozzles is 0.5 m. The ratio of the blade tip speed to jet speed is 0.90. Assuming the meridional velocity is constant and equal to 10 m/s and there is no swirl in the runner exit flow,...
