You are treating 10 million gallons per day (MGD) of water with alum at a dosage of 50.0 mg/L. Alum is available as a hydrated salt Al2(SO4)3.16H2O. Determine:(a) The monthly alum dosage required in metric tons/month (1 metric ton = 1000 kg)(b) If you assume that each equivalent of alum added to the water consumes 1 equivalent of alkalinity, determine the alkalinity consumed by alum addition in milliequivalents/L (meq/L)(c) Given that the raw water contained 30 mg/L as CaCO3 of alkalinity, is the alkalinity sufficient? What would happen if the alkalinity is inadequate?
A water contains 100.0 mg/L CO2-3 and 75.0 mg/L HCO-3 at a pH of 10 (T =25C). Calculate the exact alkalinity. Approximate the alkalinity by ignoring the appropriate chemical species. Select one: a. 167 mg/L b. 233 mg/L c. 459 mg/L d. 385 mg/L
Your organization has been hired to provide a water treatment process or device toremove toxic Chromium 6 [Cr(VI)] from water emanating from an underground source.Your organization has developed a treatment process that removes most of the Cr(VI)from the water to a residual concentration of 0.05 mg/L which is an acceptable level inline with the World Health Organisation. The underground water flows at 40 m3/h andhas Cr(VI) concentration of 100mg/L. The effluent flow rate is 97% of the influent flowrate, and the remainder of the water is discharged as wastewater. Calculate theconcentration of Cr(VI) in wastewater.
An effluent stream sample (500 mL) from a metal-working facility contains 0.52 g nickel sulphate. (i) What is the nickel concentration of this effluent stream (in mg/L)? (ii) Would you regard this concentration as suitable for discharge to the local sewage system? (iii) How much total nickel (in kg) leaves the facility per year in this stream if ~1 ML of effluent is produced?
Can you please help me in answering this question. thank you A river, flowing at 1.5 m3/s, is polluted with the pesticide permethrin and flows into a lake (100 m x 100 m 2.5 m). The steady state concentration of permethrin leaving the lake is 1.4 ppm and the average cross-sectional area of the river is 2.7 m2. The half-life of permethrin in this environment is 19 hrs. What is the concentration of permethrin entering the lake and what distance downstream of the outlet would the concentration be less than 1 ppm?
For a solution with a pH equal to 9.5, express the concentrations of H+ and OH- in units of meq/L and mg/L as CaCO3.
QUESTION: An industrial wastewater from glucose production facility will be treated in an activated sludge treatment process. It is determined that 90% of glucose is biodegradable. It is also tested that the activated sludge treatment provides 100% BOD removal. This wastewater initially contains 2000 mg/L of glucose (C6H12O6), but no other organic and inorganic species. a) Calculate input TOC, COD and BOD of wastewater before treatment.b) Calculate output TOC, COD and BOD of wastewater after treatment.

A small lake with volume 10,000 m3 has a stream flowing into it with flow rate 100 m3/day and a Toluene concentration of 1.0 mg/m3. A factory discharges 5 m3/day into the lake with Toluene concentration of 10 mg/m3 – they want to increase effluent to 50 mg/m3. Toluene decays at a rate of 0.01/day. Assume steady-state and completely mixed (CSTR). a) How would this increase in discharge concentration change the lake concentration? b) Field studies show that the same lake would be better represented by dividing the lake into two cells. The first cell having a volume of 2,500 m3 and the second with 7,500 m3. How does this affect the estimate of concentration leaving the lake? Compare with one-cell model.Assume the factory continues to discharge at 10 mg/m3 into the first cell.c) Why does modeling the lake as multiple cells impact the final concentration leaving the lake? What do you expect might happen to the final concentration leaving the lake if we modeled it as more cells? How would…
You are asked to design a disinfection process using chloramine as your disinfection agent. The influent concentration of giardia is 1000 organisms per 100 ml. The USEPA regulation requires a 3 log reduction in giardia concentration in the disinfection process. The chlorine contact tank is 30 meters long and has a cross section area of 10 square meters and the flowrate is 150 cubic meters per hour and can be modeled as a plug flow reactor. The Ct value that needed is 1100 mg/L min. It is important to know that the chloramine concentration breaks down over time due environmental factors that are beyond your control. The decay is a first order process and has a decay coefficient of 0.1 hr-1. What is the effluent giardia concentration? In order to ensure disinfection occurs we often use the effluent concentration in our Ct calculation, what is the effluent concentration of chloramine? Given the decay behavior of chloramine described above, what concentration of chloramine should I dose…
