Advantage
Characteristic
Constant filtering efficiency: as core element of filter, the uniformity of groove style filtering superposition piece reaches to international first rate standard. The filter is in effect for all kinds of suspension impurity including inorganic and organic impurity.
High efficiency backwash, energy and water saving
The unit of backwash will be finished for 7-20 sec only. In general the amount of consumed water in backwash is less than 0.5% of amount of filtering water. For viscosity impurity, high effective washing also be reached. The suitable scope is wider.
Full automatic control, flow continuously: the filtering and backwash may be carried out at the same time. The loss of pressure and flow rate produced by automatic maintenance of system is less. The backwash is carried out in turn one by one and the others work normally.
Low cost, reliable and long service lifespan system: the system has been identified through IS9002 international quality system. And all the products are tested overall before sold. It's almost without daily maintenance, installation and convenient operation, reliability transportation.
