ENVENG3200 - Spring 2020 - HW 10 - Dr. Hull 1. Compare and contrast slow sand filtration and rapid media filtration 2. Compare and contrast PAC and GAC 3. Compare and contrast disinfectants 4. Determine the inactivation rate constant for a bacterium treated with UV light, resulting in the following bacterial concentrations (CFU/mL) before treatment (at t=0) and at each UV irradiation time after treatment. Time (sec) 0 2 4 6 8 10 Concentration (CFU/mL) 154 62 19 6 3 1 5. A wastewater treatment plant receives a flow of 35,000 m3/day. Calculate the required volume (m3) for a 3 m deep horizontal flow grit chamber that will completely remove particles with a specific gravity of 1.9 or greater and a size greater than 0.1 mm diameter. Check Reynold’s number to make sure Stokes’ law applies. Assume the temperature of the water is 15 °C.
