The waste water of a city has a five day BOD value equal to 160 ppmwhereas the allowable vahue for the effluent is 18 ppm. If the dailyinflow of waste water is 0.75 MLD and the total loading can be 45 kgper hectare per day, calculate the required area of the oxidation pond.

Given: Quantity of waste water = 0.75 MLD = 75 x 105/day BOD…

A waste stream is discharging into a river at a rate of 5 m3/s. Upstream of where the waste stream enters the river, the river has a streamflow of 100 m3/s with a nitrate concentration of 1 mg/L. Downstream of where the waste stream enters, the nitrate concentration has been measured to be 3 mg/L. What is the nitrate concentration in the waste stream? Assume no change in storage in the system.
The discharge from the Renenutet sugar beet plant causes the DO at the critical point to fall to 4.0 mg/L. The Meskhenet Stream has a negligible BOD and the initial deficit after the river and wastewater have mixed is zero. What DO will result if the concentration of the waste(L_w) is reduced by 50%? Assume that the flows remain the same and that the saturation value of DO is 10.83 mg/L in both cases.
The rate of eradicating microbes through chlorination process is 0.22/min when the wastewater is flowing at a rate of 36 m3/h. If the depth of chlorination tank is 1.6 m and the width is 1.2 m, determine the required length of the tank to achieve 98% removal.
Q2-) The waste flow 18000 m³/day is treated by activated sludge process to reduce 97.5% of influent BODS proce concentration of 250 mg/L. The ratio of formed cell mass and substrate utilized mass are 0.4 and 0.8, respectively, MLVSS = 3500 mg/L, return sludge (Xr) = 8000 mg/L, decay growth rate = 0.05, and 8c = 10 days. Find the following: 1. Reactor volume and hydraulic retention time. 3. The daily amount of wasted sludge. 5. Food to microorganisms' ratio. 2. The volumetric organic loading 4. The recycle ratio, and treatment efficiency.
. A water plant with a flow of 20,000 m³/day uses 25 mg/L alum as Al,SO, 18H₂O. The sludge produced consists of the alum precipitates plus 20 mg/L of other material removed by the process. Determine the dry mass of sludge produced per day.

Coagulation aided sedimentation produces 135m³ of sludge per day. The solid content of sludge is 1% by weight and specific gravity of sludge solid is 2.7. If 20 my of suspended solids are removed from the raw water by the Al(OH)3 precipitate formed, and flow through the treatment plant is 40 MLD, then the amount of alum required per day in kg is
For the following wastewater and biomass characteristics: Q0 = 50 m3/d S0 = 60 mg NH4+-N/l Xi0 = 20 mg/l k= 2.5 mg NH4+-N/mg VSS-d K = 1 mg/l Y = 0.34 g VSS/g NH4+-N b = 0/day Calculate the volume of the CSTR required for 50 and 98% removal of ammonia by oxidation to nitrate.
