• Calculate the Hydraulic rate Vo, and BOD load of a single -stage trickling filter with the following data: Q= 30000m3/d, t=3hrs, H=2m and BOD effluent 30mg/l, Recirculation around filter is =25%Q. Assume efficiency of filter 80%.
using thCNK Tormulas. 4 Consider the feasibility of treating the wastewater from the town of Nancy (Problem 12.31) in a single-stage trickling-filter plant, as diagrammed in Figure 12.21, using high- density cross-flow media with a specific surface area of 42 ft²/ft³. Use the same filter sur- face area as calculated for stone-media filtration in Problem 12.31 (A = 4600 ft²) and a recirculation ratio of 0.5. The design wastewater temperature is 15°C. As determined from laboratory testing, the soluble (filtered) BOD of the primary effluent is 100 mg/l or less, compared to the unsettled unfiltered BOD of 160 mg/l. The soluble effluent BOD concen- tration of trickling-filter plants treating similar wastewaters is approximately 50% of the unfiltered BOD concentration. From pilot-plant studies and full-scale experience, the manufacturer of the cross-flow media recommends a reaction-rate coefficient at 20°C of 0.0030 (gpm/ft2)0.5 for a media depth of 6.6 ft (2.0 m). From these data, calculate…

A water treatment plant is required to process 28800 m³/d or raw water (density = 1000 kg/m³, kinematic viscosity = 106 m²/s). The rapid mixing tank imparts a velocity gradient of 900 s¹ to blend 35 mg/l of alum with the flow for a detention time of 2 minutes. The power input (W) required for rapid mixing is..
Design an ESP that is 98,5% efficient in treating 8050 m3/min of gas, Assume the plates are 6.1 m high and 4.1 m long. The effective drift velocity of the particles is 5.2 m/imn. The design should include the plate design (total area, layout, number), channel width, gas velocity, number of ducts, aspect ratio, number of mechanical fields and number of electrical sections total, and actual area.
During the test of a Pelton wheel, the pressure at the end of the 6.10" diameter nozzle was 515 psig when the flow is 2,615 ft/min. The peripheral coefficient is 0.46, the turbine specific speed is 6.20 rpm, and the penstock diameter is 1.5 feet. If the mechanical efficiency is 86% and electrical efficiency is 85%, determine the diameter of wheel in feet.
A closed tank of fixed volume is employed for the continuous mixing of two liquids, which enter at A, and B and are discharged completely mixed at C. The diameter of the inlet pipe at A is 150 mm and the liquid flows in at the rate of 56 dm3/s and has a specific gravity of 0.93. At B the inlet pipe is of 100 mm diameter, the flow rate is 30 dm3/s and the liquid with a specific gravity of 0.87. If the diameter of the outlet pipe at C is 175 mm, determine the mass flow rate, velocity and specific gravity of the mixture discharged.
