Drum microfilter

Smooth delivery of drum microfilter
       A microfilter is a mechanical filtration device consisting of main components such as a transmission device, overflow weir water distributor, and flushing water device. The filter screen is made of stainless steel wire mesh. Its working principle is to enter the overflow weir distributor with treated water from the water pipe outlet, and after a brief stable flow, it evenly overflows from the outlet and is distributed on the filter network inside the filter cylinder that rotates in the opposite direction. The water flow and the inner wall of the filter cylinder generate relative shear motion, with high water passing efficiency. The solid material is intercepted and separated, and flows and rolls along the spiral guide plate inside the cylinder, and is discharged from the other end of the filter cylinder. The wastewater filtered out from the filter is guided by the protective covers on both sides of the filter cartridge and flows away from the outlet tank directly below. The machine is equipped with a flushing water pipe outside the filter cartridge, using pressure water (3Kg/m ²） Spray in a fan-shaped or needle shaped manner to flush and unblock the filter screen (which can be circulated and flushed with filtered wastewater), ensuring that the filter screen always maintains good filtration capacity.

      Microfiltration machine is a practical technology suitable for papermaking wastewater treatment, which is specially developed to address existing problems such as easy blockage, easy damage, heavy maintenance workload, and high secondary investment. This equipment is a new type of equipment developed based on the national conditions of China, absorbing the technology of New Zealand Wanquan Machine. It is widely applicable for various occasions that require solid-liquid sharing, such as filtering urban domestic sewage, papermaking, textile, printing and dyeing, chemical wastewater, etc., especially suitable for the treatment of papermaking white water, achieving closed cycle reuse.

1. Simple structure, stable operation, convenient maintenance, and long service life.
2. High filtration capacity and efficiency, with a general fiber recovery rate of over 80% in wastewater.
3. Small footprint, low cost, low speed operation, automatic protection, easy installation, water-saving, and energy-saving.
4. Fully automatic and continuous operation, without the need for dedicated personnel to monitor.
