Waste water flow from a small community average 3000 m^3/day in winter and 5000 m^3/day in summer. The average temperature of the coldest one is 8 degree celcius, & the avg. temperature of the warmest is 25 degree celcicus. The average BOD is 200 mg/L with 70% being soluble. The reaction co-efficient is 0.23(d^-1) = (k) at 20 degree celcius & the value of phy =1.06 . Prepare a preliminary design for a facultative Pond Treatment System for a community ,90% of soluble BOD.
