Distilled Water has long been considered the purest form of water available. Whether you need Distilled Water for industrial machinery, medical settings, or simply prefer it for drinking and cooking, distilled water provides a level of purity and consistency that regular tap water or deionised water cannot match. At Distilled Water Supplies, we pride ourselves on delivering top-quality distilled water through a rigorous process of repeated condensation and evaporation cycles.
What is Distilled Water?
Distilled water is water that has undergone a thorough purification process using the principles of evaporation and condensation. The water is boiled until it becomes steam; the steam is collected in a separate container, cooled, and returned to its liquid state. Because most impurities—including minerals, metals, waste materials, and bacteria—are heavier than the water molecules, they remain behind during the evaporation stage.
As a result, our ultra-pure distilled water can achieve a purity level of less than 1 part per million (ppm) of dissolved solids. The pH level of freshly distilled water typically hovers just below 7, though it can shift slightly if exposed to carbon dioxide in the air. The process can be repeated multiple times, in the case of our triple-distilled water, to achieve even higher purity if required for very specialised applications.
Based on the principal that the vast majority of minerals, metals, waste materials and bacteria found in water are heavier than the molecules of the water itself, the distillation process takes place when water is boiled in a distiller and the waste materials principally salts, calcium and other ions as well as bacteria remain in the boiling chamber while the pure water in the form of steam transfers to the collection chamber where it is allowed to cool off and return it's natural liquid state. Once this process has been completed the distilled water is tested for levels of purity.
The unit of purity (of dissolved solids) is usually PPM - Parts Per Millions, and represents to number of molecules of impurities dissolved in the pure water. Depending on the levels of contamination and the levels of pureness that need to be achieved, it is possible that the process will be repeated as many as three or four times until almost all impurities have been removed from the water.
Distilled water produced using this tried and trusted method will contain an exceptionally high percentage of water molecules and an absolutely minimal presence of other gases, minerals, salts or contaminants. The principal reason why distilled water is produced is for industrial applications where water purity levels need to be very high.
Natural water is known to build up levels of minerals which can cause damage to machinery over a relatively short space of time. Whilst distilled water is that bit more expensive, in the long term, is can be a very good investment for industrial companies to use distilled water and save costly downtime. The process involved in distilling water can be quite lengthy and energy intensive. However, in recent years advances have been made in the development of multi-effect evaporators that have been found to significantly reduce energy requirements over the traditional single evaporation units that have been in use since water distillation became common practice.
The multi-effect distillation process has been designed take considerable advantage of the laws of thermodynamics. By reducing the pressure in the condensation container the boiling temperature of water in the container will be considerably decreased using this method the heated water is introduced at considerably lower pressures. Consequently vaporising at a reduced temperature considerably reducing, energy required for heating.
Through using this method, water distillation can be more efficient due to increased levels of water evaporation whilst using the same levels of energy input.
Benefits of Distilled Water
- Unmatched Purity: Because the water undergoes one or more evaporation-condensation cycles, it reaches extremely low levels of total dissolved solids. This is especially beneficial in environments where even minor impurities can cause major issues, such as in laboratories or high-end manufacturing processes.
- Reduced Risk of Contamination: The high temperature required to boil water helps kill bacteria, viruses, and other pathogens, providing another layer of safety.
- Longer Equipment Lifespan: Minerals and scale buildup from regular tap water can corrode or clog machinery over time. Using distilled water in industrial or laboratory equipment helps minimise maintenance and extend equipment life.
- Consistent Quality: Whether for medical, industrial, or household use, the consistent purity of distilled water ensures repeatable results—particularly important for scientific and manufacturing procedures.
- Versatile Applications: Distilled water can be used in everything from irons and humidifiers to automotive cooling systems and battery maintenance, preventing mineral deposits that might otherwise accumulate.
