■ Laboratory scale electrodialzer
for FORBLUE™ SELEMION

DW-Lab

The DW-Lab are miniaturized electrodialyzer units to be usedin the laboratory.
These sets contain an electrodialyzer, rectier, pumps, tanks
and all the accessories necessary to start experiments withSELEMION™ ion-exchange membranes.

Feature• Ions in solution can be separated.
• It is possible to freely set the movement amount of ions.
• It can respond ﬂexibly to adjustment of desalination waterand concentration change of raw water.
• It is easy to disassemble and clean.
• Depending on the experimental content,
membrane exchange is possible.

※ In addition to the main body, a power supply for a rectiﬁer
and a pump is attached.
※ The photograph is a prototype machine, it may be diﬀerent
from a mass production machine.

■ FORBLUE™ SELEMION
SELEMION™ is a hydrocarbon type ion-exchange membrane that has been developed and manufactured by
AGC group. Since we entered the membrane business in 1950, we have made continuous developments as apioneering company, and through this we have tried to expand the range of applications of membranes. On
the basis of our long and wide-ranging experience, we are able to propose the optimum membrane process
for each of our customers.

Summary・An ion-exchange membrane is a sheet made of organic polymer materials.
・Membranes are basically classiﬁed into two categories: anion-exchange membranes and cation-exchange membranes.
・Electrodialysis is a method of desalination and concentration involving the application of a DC current.
・Electrodialysis does not require chemicals that are commonly used in ion-exchange resin tower regeneration.
・Electrodialysis can separate valuable organic materials from salt because it only permits ionic materials to pass through the membrane.
Precautions for applying solution on SELEMION™
Oils, suspended solids, surfactants, oxidants and ionized organic polymers may cause a decrease in the eﬃciency of the membrane.
