A water treatment plant with an average flow of Q = 0.044 m3/second treats its water with alum (Al2 (SO4)3 • 14H2O) at a dose of 25 mg/L. Alum coagulation is used to reduce the concentration of natural organic matter and reduce the alkalinity of water according to the equation given below. Find the total mass of alkalinity consumed. Assume all alkalinity to be bicarbonate. (10 points) Al2(SO4)3 • 14H2O + 6HCO3- 2Al(OH)3 (s) + 6CO2 + 14H2O + 3SO2-4

A surface water treatment plant treats a 6,000 L/day flow with alum coagulation, identified by the following stoichiometric reaction: Al2(SO4)3 ∙ 14 H2O + 6HCO3- ↔ 2Al(OH)3 (s) + 6 CO2 + 14 H2O + 3 SO42- Molecular weights (g/mol): Al2(SO4)3 ∙ 14 H2O  =   594.5 HCO3-  =  61 Al(OH)3  =  78 SO42-  =  96.1 Jar tests indicate that 55 mg/L of alum are required to optimally treat the surface water. Removal of approximately 20.2 mg/L of suspended solids also occurs in this sytem. Estimate the mass of...

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...

The town of Camp Verde has been directed to upgrade its primary Waste Water Treatment Plant (WWTP) to a secondary plant that can meet an effluent standard of 25 mg/L BOD5 and 30 mg/L suspended solids. They have selected a completely mixed activated sludge system for the upgrade. The existing primary treatment plant has a flow rate of 0.029 m3/s. The effluent from the primary tank has a BOD5 of 240 mg/L. Using the following assumptions, estimate the required volume...
