3. (6 pts) Raw wastewater with initial BOD5 = 265 mg/L is treated in Wastewater Treatment Plant (WWTP), which can remove 65% of initial BOD. Students were asked to run BODs tests on the treated wastewater AFTER treatment. They used standard 300 ml bottle a. Find the volume of treated wastewater that should be put in the bottle to make sure that DO after 5 days will be at least 2mg/L (assume initial DO = 9.2 mg/L; and the bottle...
How much soda ash (Na2CO3) in kg/day do you need to add to remove calcium hardness from 200 mg/L CaCO3 to 50 mg/L CaCO3 if you have a water source with flowrate of 1000 m3/day. Consider the following unbalanced reaction that describes the process of Ca2+ removal. Ca2+ + Na2CO3 ↔ CaCO3↓ + Na+ Considering the soda ash has 96% purity and it costs $0.5/kg, how much would it cost the water treatment plant per year (365 days)?

How much citric acid (99% concentration; Molecular Weight:192.12; linear formula: HOC(COOH)(CH2COOH)2) do I need to add to a lake (volume of lake:1233 cubic meters; m3) to lower the pH from 10.51 to 7. Lake Hardness: 412 mg/l CaCO3. Lake Alkalinity: 89.8 mg/L CaCO3.
Just tell me which one is right A wastewater treatment plant treats 1000 (m3 day) of wastewater. Calculate the amount of excess sludge (kg day l) under steady-state condition, based on the following information: -Influent and effluent BOD concentrations: 200 mg Lland 10 mg L-? -Influent P concentration: 10 mg L-? -Yx/s=0.6; ka=0 (ignore the decay rate) -Content percentage of P in excess sludge: 7% The amount of excess sludge (kg day '); 64 84 114 214 the most anxious...
