Using the information in Problem 6.1, determine the design capacities for the following: a. Source (m3/d). b. Low-lift pumps (m3/d). c. Treatment plant (m3/d). d. High-service pumps (m3/d). e. Distribution system (m3/d). Problem 6.1 Estimate the water demand for a city of 100,000 people. Assume the annual average consumption rate is 647 liters per capita…

A flocculator that is 100 ft long, 50 ft wide, and 20 ft deep houses four, horizontal paddle-wheels. Each paddle-wheel has four symmetrical arms with fiber glass boards, 6.5 ft from the shaft to the center of board rotating at 1.5 rpm. Paddles are 42 ft long and 8 inches wide. The water treatment plant…

Visit us here Wridemy IntroductionBecause police interrogation of a suspect has the potential for compulsory self-incrimination, it is subject to limitations imposed by the Fifth Amendment. Determining what constitutes an interrogation and whether the individual was in custody are key inquiries that impact procedural parameters.Let’s put this into action.…

Design a vertical turbine flocculator to treat 75,700 m3/d of water per day at a detention time of 30 minutes. Use three parallel treatment trains with four compartments per train. The temperature of the water is 20∘C, resulting in values of 1.002 × 10−3 kg/(m⋅s) and 998.2 kg/m3 for and ρ, respectively. The impeller diameter…

Design an RO WTP to meet the following criteria. Influent feed TDS = 3000 mg/L. Finished water produced flow rate = 1.5 MGD. TDS in treated water = 300 mg/L. Temperature of the feed = 20∘C. Water recovery factor (r) = 90% and the salt rejection = 95%. Design pressure = 600 psi and water…

The water content of a solids slurry is reduced from 99% to 96% by gravity thickening. Assume that the dry solids contain 20% organic matter with a specific gravity of 1.0 and 80% inorganic or mineral matter with a specific gravity of 2.0. Lime sludge thickens to 5.0% solids in a gravity thickener. Assume that…

A lime softening sludge flow of 30,000 gpd is gravity thickened from 2.0% to 5.0% in a mechanical gravity thickener. The gravity thickener is to be designed using a solids loading rate of 10 lb/(ft2⋅d) and a solids capture of 85%. Assume that the thickener has a side water depth (SWD) of 10 ft, an…

A complete-mix activated sludge process (CMAS) is to be designed to treat 5.0 million gallons per day (MGD) of primary effluent having a BOD5 of 180 mg/L. The NPDES permit requires that the effluent BOD5 and TSS concentrations should be 20 mg/L or less on an annual average basis. The following biokinetic coefficients obtained at…
