Description
· Widely applicable to municipal sewage, industrial sewage and service water treatment wedge grid grille.
· Three-in-one function for filtering residue, transferring and pressing.
· Integrated filter residue washing function.
Advantages
· The shape of the grid basket and the installation angle of 35 ° enlarge the filtering area than the vertical or large-angle grid. This leads to low head loss, high separation efficiency and large processing capacity.
· Made of stainless steel and treated with acid passivation to prevent corrosion and reduce maintenance work.
· Sewage is only discharged backward after being force filtered through a screen. All the grid slag to be filtered is intercepted.
· Multifunctional. The OA1 series grill has grid slag filtration transfer, flushing and dewatering functions in a single compact unit.
· Outdoor installation equipped with anti-freeze protection device, and additional isolation measures.
· Design allows for subsequent improvements and configuration updates if necessary.
· Low maintenance workload with no lubrication required.
