Product Description

Reliable and effective mechanical solid-liquid separation

  • Built-in waste crushing 
  • Configure grid waste washing
  • Compact design

Design and Function

The equipment is installed at an angle of 35 degrees in a channel or a tank. Sewage flows into the basket drum, scum and suspended matters are intercepted accordingly.

When the water level before and after the grid reaches a determined difference in level, the waste scraping arm, fixed on the central axis, starts to rotate for cleaning.

The scraper brushes penetrates into the grid orifices, thoroughly clean the basket, removes the waste and transfer it via a screw conveyor to discharge it into a bin. The brushes are automatically cleaned during the drum rotation.

Low-head Loss | High Separation Efficiency

The shape of the grid basket and the installation angle of 35° make the filtering area much larger than the vertical or large-angle grid, so the low-head is minor., the separation efficiency is high, and the processing capacity is large.

All stainless steel

The machine is made of stainless steel and treated with acid passivation to prevent corrosion and to reduce maintenance work.

Reliable mandatory self-cleaning

Through the rotary waste cleaning, the entire filtering area will be thoroughly cleaned, and even under high pollution conditions, this mandatory cleaning can ensure an effective filtering area. In addition, it will also ensure that the grid waste will continue to be intercepted in the grid basket (before the filtering area), that is, the grid waste will not fall through the grid gap into the effluent stream during the cleaning process.

Multifunctional in one system

The OA1 series grille has grid waste filtration, transfer, flushing and dewatering functions in a single compact unit. Additional closures ensure that no odor escapes during operation of the entire unit.

Outdoor installation

Outdoor installation of OA1 series grille can be equipped with anti-freeze protection device, and additional isolation measures can be added if necessary.


The design of the OA1 series grille allows for subsequent improvements and configuration updates if necessary. Both the Screening device and the integrated grid cleaning system can be configured later.

Low maintenance workload

No lubrication is required, just regular inspection.
