Tohkemy Actifiber R Ultra Precision Membrane And Fiber Filter Media

Manufacturer: Tohkemy Corporation
Model: Actifiber R

Features

Handles High Turbidity
Can reduce raw water turbidity from a maximum of 100 NTU to below 5 NTU (using coagulant).
Reduced Installation Space
Filtration speed is approximately 5 times faster than granular media (around LV20 to 80 m/h), allowing for smaller filter tower sizes and reduced installation space.
Reduced Backwash Water Volume
Utilizes powerful simultaneous air-water backwashing, achieving exceptional cleaning results with minimal backwash water.
High Turbidity Capture Capacity
Employs large quantities of fibers measuring tens of micrometers, achieving a void ratio exceeding 90% (compared to approximately 50% for sand or anthracite). This enables significantly higher turbidity capture capacity than granular filter media.

Applications

Water Purification & Irrigation Filtration (P Series)
River Water Treatment: Manages high turbidity and fluctuating water quality.
Membrane Pretreatment: Protects membrane filtration systems (e.g., SMF).
Industrial & Reclaimed Water: Treats industrial supply and converts rainwater into reclaimed water.
Groundwater & Aquatic Systems: Removes high iron concentrations from groundwater while filtering pools and aquaculture ponds.
Circulation & Drainage Use (R Series)
Wastewater & Ponds: Provides tertiary treatment for septic tank discharge and filters ornamental/aquaculture ponds.Cooling & Recirculation: Filters cooling tower side-streams and recirculates water for bathhouses and decorative pools.
Notice: Water quality variations affect actual performance. We strongly recommend conducting a flow test before selecting filter media. Please contact your sales representative for selection guidance.

Specifications

1,000 mm Series (Compact, Light weight Type)
The filter tower is made of FRP, making it lightweight. It is ideal for locations with height restrictions.

Indicates the filter media type: P (for water purification and industrial water filtration) or R (for circulation and wastewater).
1,500 mm Series (Enhanced Turbidity Capture Capacity, High-Efficiency Type)
Cartridge-type filter media allows for easy replacement. Compared to the 1,000 mm fiber length series, it captures more turbidity, reducing the number of backwashes required. Furthermore, it enables high-speed filtration for more efficient treatment.
