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. … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more
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 … Read more

Given the following information for an oxidation ditch activated sludge process: Q = 11,400 m3/d, influent soluble BOD5 = 250 mg/L, Y = 0.6 g VSS/g BOD5, kd = 0.06d−1, KS = 70 mg/L BOD5, k = 6 d−1, MLVSS = 0.70 MLSS, TKN0 = 40 mg/L, MLSS = 3,500 mg/L, DO = 2 mg/L. … Read more
Design a fine-bubble diffused aeration system to meet an oxygen demand of 5,000 kg/d. The plant is located at an elevation of 610 meters (2,000 ft). There are two aeration basins with a total volume equal to 5,400 m3. Assume the alpha and beta coefficients for the diffusers are 0.35 and 0.95, respectively and use … Read more
A two-stage high-rate trickling filter with 200% recycle will be used to treat 5.0 million gallons per day (MGD). The influent BOD to the primary clarifier is 225 mg/L and the primary removes 30% of the incoming BOD. The effluent BOD should be 20 mg/L or less. Assume that the design BOD loading to the … Read more
