Marginal water quality can lead to scaling, sediment deposits, accumulation of sludge, and increased corrosion rates.Distilled Water vs. Demineralised WaterPurification ProcessEffectivenessUsesDemineralised Water
Demineralised water undergoes a process that removes all of its minerals and ions. This is achieved by passing the water through ion exchange resins. These resins replace the cations and anions that are present in the water with hydrogen and hydroxide, which come together to form pure water. This procesDistilled Water
To yield a purified sample using distillation, water is boiled at extremely high temperatures until it begins to vaporise, leaving behind the impurities. The vapour is collected and eventually condensed so that it converts back to a liquid state. This becomes the distilled water. While distillation is extremely effective See more on chemicals.ukIs Demineralized Water Safe Drinking Water? - EluaIn my last blog post I looked at whether or not a reverse osmosis (RO) water filtration system is the right technology for your homes or office.Towards the end of the post, I promised to look further into whether or not demineralized water is safe drinking water.
