- wet sludge contains 3% solid by weight is pumped to a filter belt press at the rate of 170,000lb/day. the dewatered sludge is 18% by dry weight and the filtrate has total nitrogen concentration of 100 mg/l as nitrogen. assume the belt press has 100% solid capture and specific gravity of the sludge in all forms is 1. Calculate the amount of nitrogen (lb/day) in the filtrate returned? Please explain with details a) 4 b) 9 c) 14 d)19 The answer is one of these optionsProblem 4In water and wastewater treatment processes a filtration device may be used to remove water from the sludgeformed by a precipitation reaction. The initial concentration of sludge from a softening reaction is 20,000 mg/Land the volume of sludge is 100 m3. After filtration the sludge solids concentration is 350,000 mg/L. Assume thatthe sludge does not change density during filtration, and there is no accumulation of sludge in the filtrationdevice. Using the mass balance method, determine the volume of sludge after filtration.3. Circular clarifiers are used to remove solid materials from water. They allow continuous treatment of water and can handle fairly large flows. Solids settle to the bottom of the clarifier and are carried away by a small stream of water (the waste stream). Most of the water exits the tank as treated effluent. Assume a clarifier receives a flow of 0.10 m3/s with a solid concentration of 800 mg/L. If the waste stream consists of 3% of the incoming flow and carries 90% of the incoming solids, a) what is the solids concentration in the waste stream, and b) what is the solids concentration in the treated effluent?
- Calculate how much additional aeration volume (expressed as a percentage) is required to upgrade a BOD removal activated sludge plant under the following conditions: • Good nitrification performance by increase in Solids Retention Time (SRT). • 90% increase in SRT (Solids Retention Time) is achieved by 35% reduction in sludge waste flow rate. • Mixed Liquor Suspended Solids (MLSS) concentration in aeration unit (X) increased by 10% and settled solids concentration (Xr) is unchanged. State clearly any assumptions that you make.The results of a jar test on a surface water supply sample revealed that the optimum dose of alum (Al2(SO4)3.14H2O) as coagulant is 17 mg/L. Furthermore, the water has total alkalinity = 50 mg/L as CaCO3; pH = 7.8; and residual turbidity at optimum alum dose = 4 NTU. The water treatment plant has a mean flow of 10m3/hour. Determine: The kg of alum per year needed in the operation of the plant. The residual alkalinity in the sample, following the addition of alum at optimum dose. Solve parts (a) and (b) if instead of alum, ferric chloride (FeCl3) were used as coagulant. Assume the numerical jar test results are the same as those with alum.Waste activated sludge can be described as a Newtonian fluid with a kinematic viscosity of 20 x 10 ft/sec. At the same temperature, the kinematic viscosity v of water is 10 ft/sec. The relative roughness of the piping system is 0.001. The pressure drop for flow of water at a Reynolds number of 10' in this piping system was determined to be 1.0 psi. If waste activated sludge flows at the same velocity through the piping" system, the pressure drop (psi) is most nearly:
- The quantity of sludge produced from an aeration tank is 2,453 kg/day. The volume of the aeration tank is 8,500 m3 and the yield is 0.55 mg VSS/mg BOD5. The water retention time is 1 day and the inlet BOD5 is 540 mg/L. Calculate the outlet BOD5 in the tank?wet sludge contains 3% solid by weight is pumped to a filter belt press at the rate of 170,000lb/day. the dewatered sludge is 18% by dry weight and the filtrate has total nitrogen concentration of 100 mg/l as nitrogen. assume the belt press has 100% solid capture and specific gravity of the sludge in all forms is 1. Calculate the amount of nitrogen (lb/day) in the filtrate returned? a) 4 b) 9 c) 14 d) 19EXPERIMENT TITLE: YIELD AND EFFICIENCY DETERMINATION FOR MEMBRANE SEPARATION PROCESS OBJECTIVES: To demonstrate the reserve osmosis via membrane separation technology. To evaluate the efficiency of membrane separation process based on reverse osmosis system. RESULT AND DISCUSSION: Based the result, at time 1 minute, the highest value of conductivity (mS/cm) was at pressure difference 15 bars (14.09mS/cm) and the lowest value of conductivity was at pressure difference 10 bars (10.01mS/cm). After 15 minutes, the highest value of conductivity was at pressure difference 20 bars (15.15mS/cm) and the lowest value of conductivity still at pressure difference 10 bars (14.36mS/cm). The value of the conductivity supposed to increase when the pressure difference increase, which mean at pressure difference 10 bars will have the lowest conductivity value, following by the 15 bars, 20 bars and 25 bars as the highest value of conductivity. This fluctuating value of conductivity was occurred…
