Please upload your full solution to the following problem. A series of experiments was conducted in a batch reactor to assess the disinfection by chlorine of the protozoan Giardia lamblia. In each experimental run, the concentration of free available chlorine was varied and the time required to kill 99 percent of the organisms was determined. The results showed that a Ct value of 100 mg-min/L was sufficient to achieve 2-log removal. Assume that the Chick- Watson model holds with n = 1. A. What value is the psuedo-first order disinfection rate coefficient k (min ¹) when the chlorine concentration is 1 mg/L? B. At a chlorine concentration of 1 mg/L and a contact time of 10 minutes, what fraction of the G. lamblia organisms would be killed? C. At a chlorine concentration of 10 mg/L and a contact time of 5 minutes, estimate the fraction of the G. lamblia organisms that would be killed. 4
Question #5. The fluoride feeder at the Lemieux Island WTP breaks down. As shown below, the well mixed tank flows into a 5 km long distribution pipe. The volume of the tank is 2.5 m³ and the treatment system serves 190 000 people who each use 200 L/d. The rest of the necessary data is provided in the figure. If the fluoride concentration in the tank is 1.0 mg/L when the feed stops, how long until the concentration of fluoride is reduced to 0.01 mg/L at the end of the distribution pipe? Assume that fluoride acts as a conservative substance. Fluoride C = 1.0 mg/L 5 km u = 0.17 m/s
Q1.Clearly indicate if each of the following is True or False 1) The amount of bypassed water in split treatment of hardness depends on material balance on Mg². 2) Most water treatment plants in Iraq are using polymers as a coagulant. 3) In drinking water, most of alkalinity comes from SO4². 4) Circle or ring system is the most common method used now to design water distribution systems. 5) Fecal Coliforms and E-Coli are generally pathogenic and we need to test them to avoid their diseases. 6) In flocculation process, we need rapid mixing to enhance formation of flocs for better settlement. 7) In filtration, the only mechanism involved is the straining. 8) It is better to travel downhill, avoid rush hours, and avoid left turn when designing a route for packers. 9) Ozone in Stratosphere layer helps prevent UV light from reaching earth and causing skin problems. 10) Transfer station is used to transfer solid waste to final destination in more efficient way.
