Description
Automatic Back-flushing Filter is a new generation self-cleaning filtration system which is integrated with a number of slotted filter elements. When the filter elements are clogged, a specially designed back-flushing arm will clean the elements one by one. As the high-end self-cleaning filter, it is especially designed for customers who take good quality and high eliability into consideration firstly .The filter consists of world-class top quality crucial parts, such as filter element, gear motor, control system, etc..
Compared with ordinary mesh type self-cleaning filter, Automatic Back-flushing Filter has unparalled advantages. It has rigid and durable V-SLOT filter element, highly uniform slot width, large filter area in single filter, super high flowrate up to 3000m3/h in single filter, fine filtration at low surface flow velocity, high reliability. It applies to the filtration of dirty water containing oil sludge type impurities, soft and viscous impurities, high content impurities, small amount of hairs and fibers.
Working Principle
The water which needs to be filtered flows into the shell through the lower bottom of the filter and enters the lumen of the filter element through the rotary table from bottom to top and be drained out through the filter elements, the filtered clean water flows out from the upper outlet of the filter, solid impurities are trapped in the inner side of the filter elements, no need of cutting off the water flow when on backwashing process, Motor drives filter wheel to rotate and at the same time the drain valve is open, each filter element will be backwashed by the filtered clean water in turns.
The pressure difference between the water pressure in filter and the atmospheric pressure can make filtration liquid flow reversely so that the intercepted impurity on inner face of the filter element can be removed, After the wheel rotates a round, backwashing process is over, then backwashing valve closed and drive motor stops.

Features
1. water supply: very less cleaning water requirement ,just 1% of the out water. The flushing time is2-15 seconds, and the whole system is continuity water supply.
2. High filtration precision: the filtration precision can be up to 20 microns, with a variety of precision filter screens.
3. Large filtration area: the standard effective filtration area is larger 7 to 40 times than the entrance area.
4. Reliable cleaning: there are a variety of control modes, such as manual, pressure difference, time, setting and PLC program logic control .
5. Low-cost and simple installation: various structure forms, suitable for installation several of conditions.
6. Long service life: more than 10 years; the filter screen is made of stainless steel, and if necessary, the filter screens of different specification can easily be replaced.
