The water coming out of the sand filtration system at a plant with Q = 1 MGD contains 100 bacteria/L when it enters the disinfection system. What must the minimum removal rate be in the pseudo-PFR 1000 gal tank to have an effluent concentration of <1 bacteria/L?

6. (1) A water treatment plant applies chlorine for disinfection so that 10 mg/L chlorine is achieved immediately after mixing. The volume of water treated each day is 25,000,000 gal. What is the mass of chlorine needed by this plant every day? (2) The disinfection takes place in a contact tank which is a CSTR at steady state. Chlorine concentration in the contact tank is constant at 3 mg/L. Effluent of this contact tank will enter drinking water distribution systems...

Problem #3: Biochemical Oxygen Demand (BOD) and Stream Quality A wastewater treatment plant designed for a community of 45,000 people has a flow of 100 gal/person/day and a BOD5 loading of 0.2 lb/person/day. The upstream characteristics of the receiving waters are: stream flow rate = 20 cfs and BOD5 = 2 mg/L The water quality standards require the in-stream BOD5 to be less than 7 mg/L in this stretch of the river. The minimum BOD removal efficiency that the treatment...

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...

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...
