Tohkemy Granular Filtration System Water Treatment Systems

Manufacturer: Tohkemy Corporation
Model: Granular Filtration System

Relationship Between Filtration Tower Size and Flow Rate

Lineup includes tower diameters from φ600mm to φ3,000mm(other sizes are available on special request).
It is recommended to calculate the filtration time per day as 22 hours or less in consideration of washing time.

We will propose the optimal filter tower specifications based on the filter media, water quality, surrounding environment, installation location, and other factors.
For chloride ion concentrations of 200 mg/L or higher, we recommend corrosion-resistant specifications.
When use pneumatic double-acting type butterfly valve, an instrument air (compressor) is required.
