Flocculation filtration equipment NFF Series

The NFF Series is a filtration equipment with a mixing tank on the filter, in which feed water containing flocculant such as PAC is agitated to form flocks.
Feed water is then passed through the filter that consists of a double layer of anthracite and sand, where filtration is conducted, to produce turbidity-free pure water.
On the other hand, as water supply continues, more turbidity accumulates on the filter, which will lead to high pressure drop.
When the pressure drop has reached a certain level, the filter will automatically backwash with air and water, discharging the accumulated turbidity to the outside of the system.
