Overview

Overview of ion exchanger- mixed bed, resin bed for demineralised water

A mixed bed filter serves for fine purification of demineralised water, or for demineralisation of smaller amounts of water. This is achieved by ion exchange, with the resin bed consisting of a mixture of acidic and alkaline resins. Regeneration is conducted with acid and lye
Design Variants of ion exchanger- mixed bed, resin bed for demineralised water

Standard design for small to large flow rates.
Not regenerative, with exchangable resin cartridges, for smallest flow rates

Ion exchange systems are utilized in water treatment to remove the excess of salts from the solution. Usually, ion exchange resin (anion, cation or mixed) is used for this purpose. Cation resin removes positively charged ions (Na+, Ca2+, Mg2+, etc), anion resin removes negatively charged ions (OH-, Cl-, SO42-, etc), and mixed bed resin is employed to remove both types of ions. One of the most popular application of ion exchange principle is the water softening for power generating industry, air conditioning, boilers, etc. Another application is deionization at the pretreatment ste p before the reverse osmosis or EDI systems when producing high-quality water for electronics, chemical or pharmaceutical industries.

Advantages

Cost efficient. Low capital investments;
Simple operation and maintenance;
Quick installation for standard size systems;
Automatic and semiautomatic regeneration.

Applications

Water softening: boilers, power generation, laundries, car washing, households, etc;
Deionization: semiconductors, pharmaceutical, chemical and petrochemical, cosmetics industries, RO and EDI pretreatment;
Separation and purification of metals, especially earth metals;
Ion exchange chromatography.
