Electrodeionisation (EDI) is an advanced water treatment method used to produce extremely pure water. EDI is usually used as a 'polishing' process to further purify water that has already been filtered, sterilised, and purified by more common methods such as reverse osmosis and membrane filtration. It is usually used in high-tech fabrication industries, such as biotech, electronics, food, and pharmaceutical factories to produce Ultrapure Water (UPW).
Demineralised water is vital in many industries, and enhances many others. However, many confusions exist about what demineralised water is, why it is important, and the best ways to achieve it. Here is a plain English guide to demineralisation!
Wychwood Water Systems has supplied and installed several water purification systems used in the chemical industry over many years.
Even though deionisation (DI) is less commonly used than reverse osmosis, many industries use this system to prepare process water for their needs. Deionised water, which meets the necessary purity standards, can be used in the pharmaceutical, microelectronics manufacturing, automotive, cosmetics, food, and other industries.
For over fifty years now, Deionisation (also known as De-Min or ion exchange) systems have played a major part in commercial water purification operations. The proven and commonly used technology comes with many benefits and reasons to be the chosen one for your business.
Ion exchange deionisers with chemical regeneration have been used for 70 plus years. Along with the development of the Ion exchange resins used within the Deionisers the process has developed over time.
These developments have enabled Deionisers to provide better quality Deionised water and to provide reduced rinse up times following a regeneration.
Businesses needing large quantities of pure process water on demand can truly take advantage of DI systems to ensure they get the necessary water for their technical processes. There are several ways in which you can implement a deionisation (DI) water system in an industrial setting.
The deionisation of water is a slightly complex, two-stage scientific process whose aim is the removal of all dissolved salts from the water. This process is used widely as one of the main processes of water purification. It involves passing the water through chambers that have been set up to trigger a chemical reaction that attracts the dissolved minerals (in the form of anions) out of the water. This article provides detailed information about the process of deionisation and the two parts of the process worth noting. More information can be found in our free Guide To Industrial Deionisation Systems, which can be accessed by following this link.
The deionisation process is ideal for your facility if you need to be able to remove minerals from the industrial water you use. This versatile method of purifying water allows you to achieve pure industrial water in more than one way. It all depends on the products your facility produces.
Bacteria is a perpetual threat to industrial water purification systems, because all systems offer any number of locations and conditions to promote bacterial growth. Facilities managers must always ensure their staff are on the lookout for signs of bacterial contamination, as not doing so can result in expensive downtime while cleaning and disinfection takes place.
