What is Purified Water used by Commercial and Domestic Window cleaners

Commercial and Domestic Window Cleaners use purified water and this article will explain what purified water is for the benefit of domestic and commercial customers in Berkshire and Surrey

Purified water is used by commercial and domestic window cleaners in Bracknell, Ascot Berkshire and Surrey and is water that has been mechanically filtered or processed to remove impurities and make it suitable for use in commercial and domestic window cleaning for customers in Bracknell, Ascot Berkshire and Surrey. Distillation has been the most common form of purified water for commercial and domestic window cleaning, but, in recent years, water is more often purified by various processes including  deionization, reverse osmosis, carbon filtering, micro filtration.

Many commercial and domestic window cleaners in Bracknell, Ascot Berkshire and Surrey  use Combinations of a number of these processes to produce water of such high purity that its trace contaminants are measured in parts per million (ppm). Purified water has many uses, largely in the production of medications, in science and engineering laboratories and industries, and is produced in a range of purities.



Distilled water is produced by a process of distillation and has an electrical conductivity. Distillation involves boiling the water and then condensing the vapor into a clean container, leaving solid contaminants behind. Distillation produces very pure water. A white or yellowish mineral scale is left in the distillation apparatus, which requires regular cleaning. Distilled water, like all purified water, must be stored in a sterilized container to guarantee the absence of bacteria. More economical alternatives will be used by commercial window cleaners, such as deionised water these are used in place of distilled water. Albeit interesting to know the distillation process commercial and domestic window cleaners in Bracknell, Ascot Berkshire and Surrey will use more suitable and economic methods to produce purified water.




Most commercial window cleaners in Berkshire and Surrey will Deionize their water. Deionized water often confused with demineralized water,  is water that has had almost all of its mineral ions removed, such as cations like sodium, calcium, iron, and copper, and anions such aschloride and sulphate. Deionization is a chemical process used by commercial window cleaners that utilises specially manufactured ion-exchange resins, which exchange hydrogen and hydroxide ions for dissolved minerals, and then recombine to form that can be used to clean windows. Because most non-particulate water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale build-up therefore most commercial and certainly some domestic window cleaners will have a deionising vessel as part of their kit .




Reverse osmosis (RO) is a water purification technology used by commercial and domestic window cleaners in Bracknell, Ascot Berkshire and Surrey. Reverse osmosis can remove a multitude of molecules and ions from solutions, including bacteria. This process is used for commercial and domestic window cleaning as well as in other industrial processes by businesses in Berkshire and Surrey. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be “selective”, this membrane should not allow large molecules or ions through the pores but should allow smaller components of the solution (such as the solvent) to pass freely.
