Fine Screen
Fine screening is a second mechanical pretreatment process that allows for finer separation of solid waste from raw water than coarse screening. Screens are typically in the range of 6 mm to 0.25 mm. Fine screen is automated most of the time due to motorization of the collection system by augers, screws, drums or scrapers.
The solid waste can then be discharged into the compaction system, resulting in weight/volume reduction and optimum dryness.
