Maximize Infiltration Efficiency And Minimize Cost

摘要

Sediments and clogging layers are inorganic and/or organic particles that settle or form on the wetted surface of a basin during its filling and operation (Bouwer & Rice, 1989). The clogging effects of even thin layers of sediment can be profound. The common methods of maintaining basins and controlling sediments clogging effects are sometimes expensive and always time consuming. All the methods first require that the basin be drained and dried. After drying, medium to heavy equipment is normally used to work the basin's bottom. The "dry and crack", sometimes called the "chip" method is employed by allowing the sediment to dry and crack, thereby opening spaces between the chips. The basin is then refilled and brought back into operation till the next draining and drying is performed.
