Internal flow microfiltration machine

Wastewater (or other raw water) is transported by a water pump and enters the internal water distribution tank of the drum grille through the inlet pipe (tank). It overflows by gravity and flows through the filtering surface of the drum grille, where larger solid objects or fibers are trapped in the rotating drum. Through the action of the internal spiral plate, they gather and move to the outlet at one end of the drum and fall into the material tank. The drum is equipped with a backwash spray pipe that can run continuously or intermittently to remove impurities that may adhere to the drum surface and prevent clogging of the grid surface. The drum grille is driven by a gear reducer and chain, and the rotational speed is adjusted by a frequency converter. The drum filter surface can be selected as orifice plate, metal mesh, or wedge-shaped grid shaped mesh, suitable for different occasions.
