Fine screening is the second mechanical pre-treatment process allowing finer separation than coarse screens of the solid waste contained in the raw water. Filtration is carried out by a 6 mm to 0.25 mm opening using perforated sheet or wedge wire. Fine Screens are most of the time automated thanks to a motorization of the system of collection by a spiral, screw, drum, scraper or conveyor table. Manual solutions also exist requiring the action of an operator for a more affordable cost. The solid waste can then be discharged into a compaction system allowing a reduction in weight / volume and optimal dryness. The Fine Screen widely used in municipal wastewater treatment plant, pre-treatment device for domestic effluents, municipal rainwater & sewage pump station, water intake of water supply plant & cooling water of power plant. It can also be used for industrial wastewater treatment, such as textile, printing and dyeing, food, fisheries, paper making, brewing, slaughtering, and tanning industry. It is regarded as the ideal solid-liquid separation equipment in the water treatment field
