Super Micro Filter (SMF) naked type

A hollow fiber membrane module that can be used not only as an immersion membrane for water purification, but also as an MBR (Membrane Bio Reactor), which is attracting attention for wastewater treatment.

Features

1. Small installation scale _and space saving
By a large membrane area with 20m2/module, the entire space for equipment can be smaller.

2. Corresponding to the increase in treated water volume
The immersion membrane device can easily handle the treated water increase by increasing additional module.

3. Stable treated water quality
Stable treated water quality can be ensured even if the quality of raw water deteriorates during rainfall in rivers _or if sedimentation is poor [bulking] during wastewater treatment.

4. 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.

5. Supports concentrated recovery of various scenes
It can also be used for concentrated recovery of highly additive products such as rare metals and SS concentration of filtered backwash water.

Use

Physical processing

・ 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

MBR
・ Responding to the increase in drainage due to increased production
・ Measures against bulking _and improvement of treated water quality
・ Improvement of water quality in existing water purification facilities
・ Reuse as reclaimed water
