Suppose you are to design a chlorination tank for killing microorganisms in the effluent from a wastewater treatment plant. It is necessary to achieve 99.99% kill in a wastewater flow of 100 m3/hr. Assume the disinfection is a first-order reaction with a rate constant of 0.2 min−1. A) First, calculate the tank volume if the contact tank is a CMF reactor. B) Then, calculate the tank volume if the contact tank is a plug-flow reactor. C) Last, what is the retention time of both reactors? *Please answer all parts of the question*

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...

You have been asked to provide a design for a rapid mix tank at a water treatme nt plant which has an average water temperature of 50F. The tank is to have a detention time (td= HRT) of 1.5 seconds, a mixing intensity (G) of 2,000/second, and treat a flow (Q) of 10 mgd. a. Identify the volume of reactor required (in ft^3 and gallons) b. Find the reactor dimensions (i.e., Depth and Diameter, in feet) if the rapid mix...

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...

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...
