WN papermaking sewage treatment micro drum filtration machine
Introduction
This micro filtration 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.
Working principle
Microfiltration machine by the transmission device, the overflow dam water, wash water plant main parts, such as mesh of stainless steel wire mesh. Will waste water from the pipe into the overflow weir cloth mouth water, 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, water efficiency, being trapped solids separation and down inside the cylinder spiral guide plate rolling, the filter tube at the other end discharge; Wastewater under guard on either side of the cartridge diversion from just below the sink drain away.
