SPIRAL ROTARY DRUM FILTER

The NWS rotary drum filter is widely used for solid-liquid separation in various settings, including residential sewage treatment, paper mill wastewater treatment, textile dyeing wastewater treatment, chemical sewage treatment, and slaughterhouse wastewater treatment. The filter media has very small voids, allowing suspended matter to be efficiently intercepted under low resistance through the centrifugal force of the screen rotation. This effectively separates micro-suspended matter in sewage.

Filter screen

The filter screen is made of stainless steel. It can resist corrosion of acid, alkali, salt, and high temperature, and it’s easy to clean.

Flushing nozzle

With the rotation of the drum and the force of the backwash nozzle, the microporous screen can be cleaned, maintaining the good condition of the equipment.

The rotary drum filter is a type of media filter device that operates based on a simple working principle. The treated water enters the overflow weir distributor from the water pipe outlet and then evenly discharges from the outlet. The water is distributed onto a filter screen that rotates in the opposite direction, resulting in relative shear motion after a short period of stabilization. This process has a high efficiency of water passing through and successfully separates solids that are discharged from the end of the filter cartridge. The filtered wastewater goes away from the outlet trough under the guidance of both sides of the filter cartridge. To maintain good filtering capacity, the filter is equipped with a flushing tube, and pressure water (3kg/cm2) is used to flush and dredge it.

Characteristics

• The rotary drum filter is highly efficient in filtering sewage and has a recovery rate of fiber of over 80 percent.
• It operates automatically and can achieve a concentration of recycled fiber of up to 12 percent or more.
• Additionally, the rotary drum filter can replace both concentration and dehydrating machines by simply changing filter screens with different meshes.
