WN Rotating drum wastewater filtration machine  for industrial sewage filter 

This microfiltration machine is absorbed New Zealand technology, aiming at China’s national conditions and development of a new type of WN type micro filter machine. It widely apply to the various necessaries occasions for solid-liquid separation, such as life municipal sewage, papermaking, textile, printing and dyeing, chemical, mining wastewater filtration, to the repeated use of a closed cycle.

Adopt 1-20mm pore filtering process. WN type micro filter machine is a mechanical filtering method. It is suitable for the solid liquid matter existing in the maximum limit; achieve the goal of solid and liquid two phase separation. Under the low hydraulic resistance, high flow velocity, intercept live solid.

This equipment is based on existing grille jams easily, easy to damage, secondary investment problems such as more specifically developed is one of the best practical technologies for wastewater treatment.

Structure and working principle

This type microfiltration machine is a kind of mechanical filtering machine, consists of transmission device, overflow water distributor, wash water device, filter screen is stainless steel wire mesh. Its working principle is to deal with water from the pipe into the overflow weir, after brief steady flow, by uniform overflow outlet and distribution in reverse direction of cartridge filter, water filter with the cylinder wall shear relative movement, high efficiency water, solids are divided by a river closure, along the cylinder spiral guide plate rolling, the filter tube at the other end. The filtrate is outflow from the tank. Outside the machine filter cylinder is equipped with water pipe, flushing water pressure (3kg/cm squared), and fan injection with flushing dredge mesh, guarantee the mesh remains good filtering capabilities.

Main characteristics

1. Simple structure, smooth operation, easy maintenance, long service life.
2. Big filter ability, high efficiency, waste water suspended solids recovery rate more than 80%.
3. Covers an area of small, low cost, low speed operation, automatic protection, and convenient installation.
4. Automatic continuous work, do not need specialist care, strain the material concentration up to 18%
