Roots Blower For Backwash System

Product Description                                                                                                          

As one of the important equipment of air-water backwashing, roots blower plays a key role. Roots blower directly supplies air to the filter, and has the advantages of high efficiency, simple equipment and convenient operation.

The air backwash technology was used in the fast filter of the small fall unit in New Jersey in 1902, and was popularized and adopted with the improvement of the technology.

The backwash blower is mainly used in the process flow of waterworks. The filter is the last process of the conventional water treatment structure in the water plant. The operation of the filter directly affects the water quality of the water plant. However, after a period of operation of many filters, the sludge content in the filter layer will increase, and the expected backwash effect can not be achieved within the design value range of backwashing strength. Moreover, the flushing duration is prolonged and the water yield is decreased, which seriously hinders the normal operation of the fast filter. The effect of backwashing will directly affect the filtration behavior. If the effect of filter flushing is not good, a series of harmful effects will be produced.

At present, there are three main ways of filter backwash: simple water backwash, water backwash, supplemented by surface flushing and air water backwash. Compared with the other two backwashing processes, air-water backwashing is the most widely used one at present.
