External rotary drum screen is one of the pretreatment solid separating devices used for small and medium waste-water treatment plants, and a device which can remove solid suspended matter continuously and effectively. In some wastewater treatments,30% to 60% of the organic inorganic solid suspended matter will be remove after filtering, and reducing greatly the subsequent work load.
