You are using an ion-exchange (resin) system for water treatment to achieve a total (TH) of 150 mg/L as CaCO3. Mg2+ in raw water = 120 mg/L as CaCO3 and Ca2+ in raw water = 150 mg/L as CaCO3. If you are required to split treatment, calculate the fraction .of influent water that will be bye-passed without treatment for hardness removal.

The amount of 38*10 6 gallons/day of raw water enters a water treatment plant to produce potable drinking water. The water source has high turbidity and hardness. The plant’s engineers have decided to use alum to address the turbidity problem and use other appropriate techniques to reduce the hardness. They performed jar tests and an optimum dose for alum was determined as 14.7 mg/L. a) Calculate the amount of alkalinity consumed (mg/L as CaCO3) b) Calculate the amount of required...

Question 1 You are assigned to carry out a preliminary design for a water treatment process. A pollutant of concern, denoted ‘A’, is known to degrade in water. But you do not know the rate law or reaction rate constant. You conduct a series of experiments. In each case, you established an initial concentration of 50 mg/L of pollutant ‘A’ in water in a sealed vessel. After a certain period, you open the vessel and measure the remaining concentration of...

A new water treatment plant will treat a maximum flowrate of 95,000 m3 /d. You have been asked to design the chlorine contact basin. The plant must achieve 0.5 log inactivation of Giardia lamblia cysts with chlorine. The CT value for 0.5 log removal at the design conditions is 36 mg-min/L. The chlorine residual leaving the basin will be 1.5 mg/L. a. Calculate the required volume of the chlorine contact basin if the basin is baffled so that the t10/τ...
