Mild Steel Mechanical Fine Screen, Feature : Automatic Control, Corrosion Resistant

The step screen consists of a series of stationary and mobile steps alternating with each other. As the effluent flows through the step screen, a screening mat develops along the surface of the screen. The mobile steps progressively lift the mat of solids  along the inclination of the screen. On reaching the top of the step screen, the solids are discharged by gravity into a screw conveyor or similar device. The low-inclination angle ensures that a screening mat is retained continuously during the entire operation and prevents the roll down encountered in steeper screens.

A consistent screening mat contributes to a uniform and highsolids capture rate. Step screen is capable of handling flows of up to 23,775 gpm / 5,400 m³/hr through a single unit.

Applications: municipal waste water treatment plants, industrial waste water treatment plants such as: paper mill, slaughterhouses, food industry, fish industry, chemical industry.

Advantages: separation of non-biodegradable solids, floating or inorganic substances, self-cleaning screen, low operating costs, available also in stainless steel tank, with nozzles.
