This section is the head of the waste water treatment plants and for almost any application where fine screening is required. Its aim is that to eliminate all coarse materials which are present in waste water and that its presence, if not properly removed , would cause obstruction problems to following water treatment machines. The unit uses a perforated screen bed that is cleaned by slowly rotating brushes. The brushes remove screened particles and a scraper system discharges them from the unit. High quality stainless steel brushes are used in this system.
