Mechanically Raked Bar Screen

Intercept solid impurities: intercept suspended solids (such as branches, plastic bags, hair, etc.) in sewage through the stepped mesh components to prevent them from entering the subsequent treatment equipment and causing blockage or damage. The mesh gap can be customized to 1-10mm to meet the needs of impurity separation of different particle sizes, especially suitable for high-precision pretreatment before MBR membrane process (0.5-3mm interception).

Avoid pipe blockage and poor water flow to ensure the stable operation of the sewage treatment system.
It can clean 30%-60% of organic/inorganic suspended solids, significantly reducing the load of subsequent biochemical treatment or membrane process.

Applicable to municipal sewage treatment, industrial wastewater (such as textile and papermaking industries) and pump stations, water inlets of water plants, etc., as a pre-screening equipment. Large inclination installation (60°-90°) saves space, while reducing impurity accumulation through the mesh self-cleaning design.

Equipped with a drive device and a cleaning system, it supports liquid level difference sensing or timed automatic start and stop, reducing manual intervention.
The mesh plate is realized through a reverse cleaning brush and a high-pressure spray device. Daily, only the chain lubrication and tension need to be checked, and the maintenance cost is reduced by 30% compared with the traditional grille.

Stainless steel material and fully enclosed design are corrosion-resistant and change the operating environment.
The mesh plate design with different tooth shapes improves the wet and slippery environment and has ventilation and light transmission functions.

Through the above functions, the stepped mesh plate grille realizes separation, stable operation and intelligent management in sewage pretreatment, becoming a key equipment to improve sewage treatment efficiency.
