Tohkemy SMF Naked System Water Treatment Systems

Tohkemy SMF Naked System Water Treatment Systems

Manufacturer: Tohkemy Corporation
Model: SMF Naked System

Features

Small installation scale and space saving
By a large membrane area with 20m²/module, the entire space for equipment can be smaller.
Corresponding to the increase in treated water volume
By installing to existing water purification facilities, it can correspond to the increase in treated water volume.
Stable treated water quality
Stable treated water quality can be ensured even if the quality of raw water deteriorates during rainfall in rivers.
Enables water recycle
A PVDF membrane with a nominal pore size of 0.05 μm provides clear treated water that can be used directly as miscellaneous water.

Applications

A water purification facility with raw water of a river which turbidity rises sharply when it rains.
Improvement of water recovery rate by concentrating and collecting backwash wastewater from the filter
Improvement of water quality in existing water purification facilities
Recycling wastewater such as miscellaneous wastewater
