H2. Consider the treatment of a wastewater with the following characteristics: T = 25°C, total flow 650 m3/d, wastewater composition: sucrose (C12H22O11): C = 400 mg/L, Q = 250 m3/d, acetic acid (C2H4O2): C =940 mg/L, Q = 350 m3/d a) Estimate the methane production, from the anaerobic degradation of the discharge using the Buswell equation, in m3/d b) Calculate the total concentration of the residual water in terms of COD, the total mass flow of COD in the residual water (kg/d) and estimate from this last data the production of methane, in m3/d.
Q- One hour triangular unit hydrograph of a watershed has the peak discharge of 60 m³/sec.cm at 10 hours and time base of 30 hours. The findex is 0.4 cm per hour and base flow is 15 m³/sec. Find the catchment area of the watershed.
Q- A river has a flow of 1000 million litres per day (MLD). BOD5 of 5 mg/litre and Dissolved Oxygen (DO) level of 8 mg/litre before receiving the wastewater discharge at a location. For the existing environmental conditions, the saturation DO level is 10 mg/litre in the river. Wastewater discharge of 100 MLD with the BOD5 of 200 mg/litre and DO level of 2mg/litre falls at that location. Assuming complete mixing of wastewater and river water, the immediate DO deficit (in mg/litre, round off to two decimal places), is
10-1. Design a slow sand filter system for a community which has a projected popula- tion of 3000 and an average per capita usage of 300 L/day. Use the Goodrich formula of Chap. 2 to estimate the peak flow rates, and size the system so it can produce water at the maximum weekly rate with one unit out of service. The design filtration rate is 6 m/day.
Q1) Stabilization ponds receive a wastewater flow of 350 m³/d with a BOD of 320 mg/l. If the BOD loading is 2.8 g/m²/d calculate the total surface area and storage available between the 0.6 m and 1.5 m depuis assuming a waier loss of 0.27 mm/d during the winter months. winter ALL

There are currently 420 inhabitants in the small village of Pravino. The population is estimated to increase to 940 in thirty years. The current average peak flow is 1.2 L/s and is expected to increase to 2.14 L/s by 2050. The organic load is approximately 45 g BOD5/capita/day. The community is considering a free surface wetland or a lagoon to treat their wastewater. 1. Use the BOD loading to estimate the maximum surface area (in ha) required for a free surface wetland to serve the community by 2050 and remove BOD to 30 mg O2/L and TSS to 30 mg/L.
Explain the design procedure for sanitary and storm sewer? According to your observation which type of sewer system is more effective? A catchment is having total area of 60 hectares. The rainfall intensity relation with duration ii. for this catchment is given by the relation I=100/(t+20),Where I is in cm/h and t is duration of rain in min. a) What will be the storm water runoff from this catchment if the average imperviousness factor is 0.64, and time of concentration is 35 min?
