WebTwo, circular primary clarifiers are to be designed to treat domestic wastewater following preliminary treatment. State regulatory requirements stipulate the overflow rate must be 800 gpd/ft2 at the average daily flow and 2,000 gpd/ft2 at the peak hourly flow. The detention time should be between 1 and 2 hours at ADF. WebThe design of the sewer is verified by checking the velocity of wastewater at different flow rates. The velocity of wastewater should be greater than the self-cleansing velocity under the minimum hourly rate of flow. Conclusion In conclusion, a sewer is commonly designed to attain self-cleansing velocity at the minimum hourly rate of flow. delete cities weather app iphone
