‌Inlet Screen in Wastewater Treatment‌

The ‌Inlet Screen‌ is a critical ‌mechanical bar screen‌ and ‌automatic bar screen wastewater treatment‌ device, engineered to act as both a ‌coarse screen‌ and a ‌rotary fine screen‌ in municipal sewage plants, industrial facilities, and ‌bar screen water treatment‌ systems. Installed at the intake stage, it efficiently intercepts large debris (e.g., rags, plastics), fibers, and particulate impurities, safeguarding downstream equipment such as ‌rotary drum screens‌ and ‌drum filter screens‌ from clogging or damage. By integrating ‌mechanical bar screen design‌ principles with automated cleaning mechanisms, this system ensures robust solid-liquid separation while optimizing space efficiency and operational reliability in ‌bar screen wastewater treatment‌ processes.
The ‌Inlet Screen‌ is a primary ‌coarse screen‌ device installed at wastewater treatment plant intakes to intercept large debris, such as rags, plastics, and organic matter, protecting downstream equipment like pumps and ‌rotary drum screen wastewater‌ systems‌. Typically designed as a ‌mechanical bar screen‌, it employs a series of vertical or inclined bars spaced to block coarse solids while allowing liquid flow. Advanced models integrate ‌automatic bar screen‌ mechanisms, where a raking system removes trapped waste based on pre-set differential water levels or timers, minimizing manual intervention‌.

‌Inlet Screen Structure Principle

The main structure of the internal flow type grille: filter orifice plate, sprocket chain, main frame, Flushing rods, clean rotating brushes and filter residue collection arts, grille housings, drive motors, system seals, etc.

Filtration principle: The sewage to be filtered enters the interior of the grille from the middle of the grille inlet frame of the perforated plate. The sewage flows out of the perforated plate from both sides of the grille, and suspended matter such as filter residue, hair, and fibres are trapped on the inner wall of the perforated plate. When the filter orifice plate is running, the material trapped on the innerwall is lifted up to the top, and a pressure flushing water rod isprovided on the outer side of the top plate. The orifice plate is automatically rinsed by the pressure water, and the trapped filter residue material is washed under the inside of the orifice plate. Inside the collecting water tank, at the same time, the filter plate is re-cleaned and configuredto rotate the brush online, and the rotating brush operates in conjunction with the washing rod and mechanical rotation. For example, the washed orifice plate is cleaned again by the rotating brush, and finally, it flows from the conveying tank to the filter press for dehydration. The entire filtration process and press dehydration are carried out in a continuous, automatic state.
