Underdrains Precoat filters Cane and sugar beet processors make extensive use of screens in various washing, dewatering and solids retention functions. Traditionally, these screens have consisted of perforated plate used alone or in combination with wire mesh - an adequate design but one subject to plugging, breaking and premature wearout. Johnson screens solve these and other problems. Dewatering is faster because of the high open area of a Johnson screen.
Separation is enhanced by the close-tolerance, precisely sized screen slot openings.
Service life is extended by our screens high tolerance for abrasive, corrosive or high stress conditions. Maintenance is reduced because our special slot design creates a plug-resistant screen.
