Whether filtering water or air streams, Cambridge has the materials and mechanical systems to develop optimal, plant-specific solution. We offer both single-flow and dual-flow screens. With single (thru) flow screens, water flows through the screens from front to back. Refuse is carried up the ascending tray and discharged into a draw for disposal. Dual-flow type screens are capable of handling higher capacities. Their design allows water to flow through the ascending and descending runs plus the curved bottom of the screens simultaneously. Refuse disposal is the same.
