Demin plants consist of two pressure vessels; one containing cation and the other containing anion exchange resins. Raw water passes through the cation vessel first, where positively charged ions are chemically exchanged for hydrogen ions. It then continues to the anion vessel where negatively charged ions are chemically exchanged for hydroxide ions. The Hydrogen and Hydroxide ions combine to create pure water.
A demin plant then needs to be regenerated with hydrochloric acid and sodium hydroxide when necessary so the site where the plant is installed needs to have COSHH Regulations.
This provides the highest quality water in constant supply. It’s simple, water is forced through a semi-permeable membrane which rejects all unwanted impurities. The membrane will only allow pure water molecules to flow through, resulting in all contaminants including bacteria, chemicals and heavy metals being removed and flushed to waste.
If a solution of salts in water is separated from a source of pure water by a semipermeable membrane, the tendency of the pure water is to pass through the membrane to try and dilute the salt solution which forces pure water through the membrane, thereby concentrating the salt solution.
Water softeners work by a process know as ion exchange. The hard water passes through a high-quality cation exchange resin column inside a pressure vessel.
The resin removes the positively charged Calcium and Magnesium ions from solution and exchanges them for the ions of Sodium. When the resin becomes exhausted it is regenerated by drawing a solution of common salt called brine through the column. During regeneration, the hard metal ions are then released from the resin and replaced again with those of Sodium from the brine. The unwanted ions are flushed to drain along with the excess brine. Regeneration takes between 60 to 180 minutes depending on the size of the softener.
