1. A wastewater is treated in an aerobic CSTR with no cell recycle. The following hold: Ks= 50mg/l; q^=5mg/mg VSSa-d; Kd= .06d-1; Y= 0.6; S°=220mg/l; fd= 1 a. Determine Ɵcmin, Ɵclim, Smin
A municipal wastewater treatment plant employs three circular primary clarifiers arranged in parallel, following the bar screen and grit removal chamber. The plant receives 12 MGD. Each clarifier is center-fed (water enters at the center and exists at the perimeter).The clarifier radius is 56 ft and depth is 10 ft.What is the hydraulic loading rate (critical velocity) in each clarifier in units of ft3.ft-2.hr-1 ?
Asking for a solution please
3. Circular clarifiers are used to remove solid materials from water. They allow continuous treatment of water and can handle fairly large flows. Solids settle to the bottom of the clarifier and are carried away by a small stream of water (the waste stream). Most of the water exits the tank as treated effluent. Assume a clarifier receives a flow of 0.10 m3/s with a solid concentration of 800 mg/L. If the waste stream consists of 3% of the incoming flow and carries 90% of the incoming solids, a) what is the solids concentration in the waste stream, and b) what is the solids concentration in the treated effluent?

The folowing treated effluent in a dairy factory at Mosul city is discharge to a stream; Q= 30 L's, DO-2 mg/L, 5-day BOD-40 mg/L, ka= 0.1/day, and T-20°C. Upstream from the outfall the watercourse has the following characteristics: Q= 0.27 m/s, DO-8 mg/L, 5-day BOD=2 mg/L, and T=20°C. The stream has a k= 0.2/day. Calculate the critical dissolved oxygen concentration downstream, and the distance from the outfall to this point assuming a mean velocity of 0.6 m/s in the river. The saturation value of DO at the temperature of the stream is 9.17 mg/L
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.
