Self Cleanign Filter

Product specification

Self cleaning filters can be apply as a pretreatment of RO and UF filters. Filter design in this systems can be in-line so that it will cause easy and less piping. When feed includes fibrous, gluey and sticky contamination the filter will be equipped with a brush which is directly located below disc.

Self cleaning filter with 100-300 micron mesh size ( according to UF requirements) is applicable before Ultrafiltration. And 50 micron mesh size can be apply as a RO membranes pretreatment unit.

Filtration is continuous and there is no need to side filter during washing operation. Due to Bernoulli principal during washing, there is a minimum water waste ( 99% efficiency)

Washing mechanism are as follows:

فیلترخودشوینده

1- During normal filtration, dirt particles accumulate from top to bottom on the inside of the filter insert according to fluid mechanical laws, when the set time or differential pressure reached the particle drainage valve will open

2- In second phase a after the valve opens the flushing disc moves into the filter sieve without touching it. The outer diameter of the disc is smaller than the inner diameter of the sieve.The flow velocity increases within the gap between flushing disc and strainer. This causes a decrease of pressure between them. Dirt particles are sucked out of the filter element
