In wastewater treatment, what is the required open screen area (m2) for reaching this screen velocity during treatment of the rain weather flow when dimension of the pre-treatment unit for the wastewater treatment plant is receiving a dry weather flow (dwf) of 18000 m3/day, and assuming that the flow doubles during rain, where the bar screen is used to remove the coarse waste with the rain water flow velocity in the screen channel is 0.5 m/s and the flow -through velocity of the clean screen (V) is 0.9 m/s?
