The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.

Question

A wastewater treatment plant is operated at a steady state DO concentration of
1.5 mg/L. If the temperature of the wastewater is measured at 10 °C, a= 0.8 and B = 0.95
and the KLa reported by the aerator manufacturer at 20°C in tap water is 5 hrt, estimate
the oxygen uptake rate (in mg/L-min) in the aeration basin. You can assume 0=1.024. If the
aerator's oxygen transfer efficiency is 24%, what would be the mass of air (kg) required per
hour in a 8500 m³ tank? What volumetric flow rate would you have to supply (m³/hr)?

Hello can you answer this question for me? All the info you need to answer the question is here. Thamnk you A salt lake doesn't have an outflow since evaporation totally balances the intake flow. This is the salt content of the lake is 52g/L, the volume of the lake 2.5 x 1011 m3 The lake's intake (of salt) stream has a 0.18 g/L concentration and moves at a pace of 3.7 x 109 m3/yr. How long ago did the outflow halt if the lake's concentration was 0.18 g/L at the start?
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?
