2. A lake has a volume of 9 million m³ and an average depth of 3 m. There is an influent stream coming in to the lake with a flow rate of 20 m³/s and an ammonia concentration of 1 mg/L. Also, there is a wastewater outfall coming into the lake with a flow rate of 1 m³/s and an ammonia concentration of 180 mg/L. There is an effluent stream leaving the lake. The ammonia in the lake has a decay rate of 0.18/d. a. Draw a schematic diagram showing different inflows and outflows from the control volume. Indicate the values of different variables in the diagram. b. What is the steady-state concentration of ammonia in the lake?

8 Determine the solid loading rate on a secondary circular clarifier (diameter = 20 m) if the plant influent load is 2 ML/d. The recycle flow from secondary clarifier to the activated sludge system (aeration basin) is set to 10% of the influent load. It is also known that the aeration basin produces an MLSS (mixed liquor suspended solids) concentration of 3000 mg/L.
All values should not be rounded off until the final answer.
Q1: The design flow for a water treatment plant (WTP) is 1 MGD (3.8x10 m³ /d). The rapid mixing tank will have a mechanical mixer and the average alum dosage will be 30 mg/L. The theoretical mean hydraulic detention time of the tank will be 1 minute. Determine the following: a) the quantity of alum needed on a daily basis in kg/d, b) the dimensions of the tank in meters for a tank with equal length, width, and depth, c) the power input required for a G of 900 sec' for a water temperature of 10 °C. Express the answer in kW, given that u = 1.307 × 10³Kg/m.s.

The pipe carrying wastewater contains 5.5x 105 fecal CFU/liter. Determine the length of pipe required if the maximum permissible fecal coliform concentration that may be discharged is 3000 fecal CFU/L for linear velocity of 0.85 m/s. Assume that the reaction rate constant for the destruction of the fecal coliform is 0.22 per min.
