Biological Processes

Biological solid waste includes bacterial and contaminated waste produced by living individuals. Its treatment is essential to prevent the spread of any air-borne or water-borne diseases or diseases transmitted from one organism to another in a food chain. There are many benefits of the biological solid waste treatment and some of them are: the minimized quantity of waste substance, waste control, eradicating any disease-causing pathogens, generation of biogas, composting, anaerobic digestion, bio drying, mechanical biological treatment, microbial fuel cell, phytoremediation, and biofiltration. The final products of the biological solid waste treatment may be recycled to obtain organic fertilizers or disposed of in SWDS (Solid Waste Disposal Site) after proper treatment.

A drinking water treatment plant wants to compare the efficacy of three different solid coagulants, Alum [Al(OH)3(s)], Lime (CaCO3(s)), and Ferric Chloride (FeCl3(s)), for removing the phosphate (PO43-) level to 1 mg/L. The following are the equilibrium reactions [and the respective equilibrium constants (or solubility products, Ksp)] that result in phosphate removalfor each solid, the second reaction being more relevant in each case: Alum: Al(OH)3(s) ↔ Al3+ + 3OH- AlPO4(s) ↔ Al3+ + PO43- Ksp = 9.84 x 10-21 Lime: CaCO3(s) ↔ Ca2+ + CO32- Ca3(PO4)2(s) ↔ Ca2+ + PO43- Ksp = 1 x10-27 Ferric Chloride: FeCl3 (s) ↔ Fe3+ + 3Cl- Fe(PO4)(s) ↔ Fe3+ + PO43- Ksp = 1x10-26.4 What concentrations of Fe 3+, Al3+, and Ca2+ will be needed to maintain a phosphate concentration of 1 mg/L? What would be the best choice of solid coagulant for the Drinking Water Treatment Plant?…

A Haldane modification of the Monod reaction is often used to describe the kinetics of substrate utilization when the substrate itself is toxic at high concentrations (phenol is an example of this). (1) Calculate the effluent concentration for a substrate exhibiting Haldane kinetics from a CSTR (continuously stirred tank reactor) and (2) compare this with the value if the substrate were not inhibitory (S2/Ki = 0) for the following conditions: V = 24 m3 Q = 9 m3/d S0 = 400 mg/L Y = 0.5 mg/mg q = 7.5 g/g•d K = 7 mg/L b = 0.1 d-1 Ki = 15 mg/L Hint: θx = (active biomass in the system)/(production rate of active biomass) = V/Q And 1/θx = (YqS)/(K + S + S2/Ki) – b

If the capacity of the aeration tank is 2000 cu.m, determine which of the following statements is true. a) The aeration tank is not operating in an ideal condition; there are excess bacteria that might go with the treated water b) The aeration tank is operating in good condition; BOD and bacteria are in ideal balance c) The aeration tank is operating in good condition; however, there is a need to control the flow rate of the feed d) The aeration tank is not operating in an ideal condition; need to add more bacteria to treat excess BOD
A Granulated Activated Carbon (GAC) adsorption laboratory column 10cm in diameter and 3m deep, is found to produce good results in COD removal when operated at a flow of 50L/h. The porosity of the GAC is 0.5 Calculate the following: The application rate in m/h. The residence time, t, in the column. The volumetric flow rate, Vb, in bed volumes per hour, for this residence time. You need to design a GAC system consisting of two columns in series for treating the same water at a rate of 0.5 ML/d. Practical considerations limit the diameter of the columns to 3m. Calculate the minimum required height of the columns.
You are being consulted for the design of a coagulation-flocculation basin for a water treatment plant. Ferric sulfate is available as a commercial coagulant and is popular at removing turbidity and color. The chemical reaction for its addition to water is: Fe2(SO4)3 + 3Ca(HCO3)2 ----> 2Fe(OH)3 (s) + 3CaSO4 + 6CO2Results of a jar test to determine the optimal coagulant dose are provided below. The initial water sample has a pH=6.5 and turbidity of 30 NTU.
