1,Products Specifications
BOCIN-BW series automatic suntion backwashing filter is a kind of filter which can provide a wide range of comprehendsive use of industrial ,it can guarantee the purity and reliablity of filtred liquid.
This series can be equipped with different amount of elements to provide maximum filtering area in each filter housing ,this makes the filter to have smallest pressure lose when working.the pressure design of filter body is usually based on the chemical pipeline filter and steel pressure vessel design standards, the filter also can adapt to the special requirement of other design criteria ,filter main body has the material such as carbon steel ,stainless steel ,and duplex phase steel ,and etc,.at the same time we also can provide special material such as titanium ,pure nickel and etc.

BOCIN-BW series automatic suntion backwashing filter
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 drivers filter wheel rotating and at the same time the drain valve was 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.
