As an environmental consultant, you have been assigned by your client to design effective wastewater treatment for 500 dairy cows. 1) 11) 111) Calculate wastewater produce (m³/day), if 378 L/cow is generated every day. Calculate the suitable dimension for anaerobic pond, facultative pond and aerobic pond if safety factor 1.2 (20%). Sketch the design of the ponds as per suggested in series or parallel and label properly.
Expert Answer
Sol.- Given: Number of dairy cows, N = 500 Rate of wastewater generation, R = 378 L/day i) Total wastewater produce, Q = N*R = 500*378 = 189000 L/day = 189 m3/day, Ans. ii) Comparison of anaerobic ponds, facultative ponds and aerobic ponds
