Q6) Aluminum salt is used for chemical precipitation of phosphate from industrial wastewater. Thesuspended solid (SS) concentration in wastewater is 0.25 g/l and the phosphorus concentration associatedwith the SS is 0.007 g/l as P.If the laboratory analysis of wastewater indicated that the alum dose of 1.5 moles Al/ 1 mole P wouldprovide sufficient phosphorus removal, estimate the quantity of the resulted dry sludge that is generatedand must be removed daily. The following data are available:Alum formula: Al2SO4.18H₂O, Total phosphorus concentration= 0.017 g/l as P, wastewater flowrate=4000 m³/d. [Al3+ PO4³ → AIPO4]

The amount of alum required to remove phosphorus from the wastewater is calculated as…

NaCl crystal is created from seawater within a series of evaporation and crystallization. A feed of 10 tons/hr of seawater containing 3.6% NaCl was mixed with a recycled stream of saturated brine solution at 40 Celcius before being fed to an evaporator where it is heated to 120 Celcius. The concentrated brine solution produced from the evaporator is 54% NaCl. This brine solution was fed to a crystallizer where it was cooled down to 40 Celcius to crystallize the NaCl. The crystals produced are 96.5% NaCl. The excess saturated liquor was mixed to the fresh seawater for recycle. The solubility of NaCl at 40 Celcius is 0.366 kg of water (H2O). Calculate: NaCI Crystals + H,0 Saturated Crystallizer Brine at 40°C Evaporator Mixer Seawater Concentrated Brine at 120°C Water Vapor a) crystals production rate kg/hr b) concentrated brine solution in kg/hr c) recycle stream flow rate in kg/hr

Acetone is used in the manufacture of many chemicals and also as a solvent. In its latter role, many restrictions are place on the release of acetone vapor to the environment. You are asked to design an acetone recovery system having the flowsheet illustrated in figure. As a starting point, make a material balance for the system. All the concentrations shown in figure of bth gases and liquids are specified in weight percent to make the calculation simpler.
In the production of canned corn, 100 g of corn suspension contains 2.5 g fructose, 50 g of water, and 47.5 g solid particles is used. This solution is mixed with 100 g molasses, which contains 50 g of sucrose, 1 g fructose, 18 g water, and 31 g solid particles. Water, W is added to obtain a diluted sugar solution containing 2 g of fructose per 100 g of suspension in the final product. The mass flow rate of the corn suspension and molasses is 125 kg/h and 45 kg/h, respectively. Based on the given situation, a) draw the process flow diagram with the detailed information of the materials. b) state ONE (1) assumption to facilitate the problem-solving. c) determine the amount of water, W that is required for this process in kg/h. d) determine the final sucrose concentration in g per 100 g suspension. e) list in a table the amount of each component and the total amount for each material flowing in and flowing out of the mixing process. All units must be in…
You are given a 1.25 gram mixture of calcium nitrate and calcium chloride. You dissolve this mixture in 200.0 mL of water and add an excess of 0.300 M silver nitrate. You collect and dry the white precipitate which forms and find it has a mass of 0.325 grams. Calculate the percent calcium chloride by mass in the original mixture.
