In a primary settling tank of a domestic wastewater treatment plant, 1000kg of dry solids are removed daily. It is planned to thicken these solids in a gravity thickener. All the parameters required for the solution of the problem will be chosen (assumed) from the appropriate values. a) Dimension the line to be used for sludge conveying. b) Determine the power of the pump to be used. The head loss multiplication factor can be calculated using the following equation. For undigested sludge K=0,125.P20,1656.P+1,5733 where P is the % of sludge solids
