Water quality and purity levels required for microelectronics can fall into the ultrapure water category as conductivity levels of the water are often critical. To achieve the industry standard 18 megohms, removal of all ions and salts is required which often involves the use of reverse osmosis systems in combination with deionising systems to remove all elements including elements that are difficult to extract, such as silica.

This ultrapure water is usually stored before use and recirculated through 0.2-micron filter cartridges to remove any bacteria and ultraviolet disinfection systems to suppress bacteria growth.

Stages of Filtration & Water Treatment

Particle Removal

Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.

Chlorine and Organics Removal

Helps the taste and odour of the liquid and where present, protects RO membranes from chemical attack.

RO Water Production

Very pure water is produced using reverse osmosis membranes to separate the majority of salts and ions from the feed water and sending the salts and ions to waste or re-circulation.

The use of a mixed-bed resin of anion and cation, attracts all salts and ions, removing them from the water.

TDS Monitoring

Devices that measure the conductivity of water between 2 probes provide a good indicator of the ions and salts content.

Ultraviolet Disinfection

UV light impedes bacterial growth by sterilising the DNA of microorganisms, suppressing bio-film and bacteria colony growth.
