A primary settling tank of 28 m diameter and 2.8 m effective water depth is required to treat 14,000 m3 of waste water per day. Calculate: 1. The detention time (in hours) 2. The surface flow rate (in m/hour) 3. The size, in mm, of the particulate matter, of specific gravity 1.2, the tank has been targeted to remove if the dynamic viscosity (uw) of the wastewater is 1.25 x 10-3 kg/m.s
