A new disinfection system is being designed for a treatment plant with a flow of 400 m3/min. The desired chlorine concentration in the treated water is 7 mg/L. (a) It is proposed to inject a concentrated chlorine feed solution into the main flow. If the chlorine concentration in the feed solution is 150 mg/L, what flowrate is required? (b) If the applicable Ct factor is 180 mg-min/L, what volume of chlorine contact chamber is needed? (c) State whether the chlorine contact chamber should be: Round or Long and skinny

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...

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...

A wastewater treatment plant designed for a community of 60,000 people has a flow of 100 gal/person/day and a biochemical oxygen demand (BOD) loading of 0.2 lb/person/day. The treatment plant has a permit limit for BOD equal to 15 mg/L. a. (6 pts) What is the concentration (in mg/L) of BOD coming into the plant (i.e., as raw, untreated sewage)? b. (2 pts) When the treatment plant is treating its waste and meeting its permit limit, what is the removal...

The volumetric flow to the ACME wastewater treatment plant is 25 MGD. The influent soluble BOD5 is 200 mg/L and the effluent soluble BOD5 is 8 mg/L. The plant is designed to operate with a mean cell (biomass) residence time of 10 days. The yield coefficient is 0.6 mg biomass/mg substrate, and the biomass decay rate is 0.09/day. The reactor is to operate at a biomass concentration of 2500 mg/L. The thickened underflow biomass concentration from the secondary clarifier is...
