● Suitable for high turbidity
Raw water with its maximum 100 NTU turbidity would be treated with the value less than 5NTU (with coagulant).
● Reduction of installation space
Since the filtration speed can be increased by about 5 times compared to the granular filter material (approx. LV20~80m/h), the size of the filtration tower can be reduced to save the installation space.
● Reduction of washing water volume
Simultaneous cleaning of strong air and water is adopted for cleaning, and a large cleaning effect can be obtained with a small amount of cleaning water.
● Large amount of turbidity captured
The void ratio is 90% or more (sand and anthracite is approx. 50%), and since a large amount of fibers of several tens of μm is used, the surface area is large, and the amount of turbidity trapped is larger than that of granular filter media.

【1000mm series (Compact and light weight type) material: FPR】
Light filter vessel made from FRP. No need to put media into tank at user’s place.

【1500mm series (Turbidity captured up and high performance type) material: SUS】
Filter media replacement is easy with the cartridge method.
In comparison with fiber length 1,000mm series, larger amount of turbidity captured, great decrease of washing times.
And more, high speed filtration, more efficient treatment.

Fiber filter media [Actifiber®] offers features such as space savings and reduced wastewater volume.

【For purification & industrial water filtration (P series)】
●Measures for high concentrated river water, changed water condition, and prevention against contaminating into sewage with rain water
●Pretreatment before membrane filtration such as SMF
●Decontamination of industrial water
