The filtration precision is 0.5 ~50 μm. The system is fully enclosed to prevent contamination, which could provide excellent filter cartridges cleaning and regeneration performances. Timing or differential pressure PLC connected to DCS is used for system operation, which could be able to switch to long-term continuous operation.
APPLICATION CONDITIONS
Filtration and purification of industrial liquids at high and low temperatures; and col-lection of solid particles.
ADVANTAGES
Parallel operation of two or more units; online back washing; continuous and stable operation processes; long service life; automatic control; easy operation; convenient maintenance; small sewage discharge; and application in high temperature and corrosive conditions.
WORKING PRINCIPLE
Double-tank automatic back washing filter is composed of two filters (A and B) that are operated in parallel. During the normal filtration operation, one filter will be operated at full flow rate and the other one is used as backup. When the operation differential pressure of the system (the pressure drop between inlet and outlet) reaches the set value or the operation time of the system reaches the set value, the system will automatically switch the working filter to ensure the uninterrupted operation of the whole filtration system.
