DM Plants
DM plants are a demineralization-based process of removing excess minerals and salts using an ion exchange process. The Doctor Fresh DM plants use distillation, deionization, and membrane filtration technology to remove all sorts of minerals from raw water. The process to remove the excess of minerals like sodium and calcium along with salts is termed deionized water. Choose Doctor Fresh DM plant gives you high-quality drinking water better than any bottled or distilled water. When it comes to demineralizing water, the raw water is passed through the ion exchange resin beds to pull out excess ions.

Frequently Asked Questions
Demineralization is the process of elimination
of mineral salts present in the water by using an ion-exchange process. The
demineralization water is entirely free of dissolved minerals due to distillation,
deionization, membrane filtration, and others.
Raw water can pass through two small
polystyrenes bead-filled beds in the DM plant. While cation gets exchanged with
the hydrogen ions in the first bed, the anions are exchanged with the hydroxyl
ions in the 2nd bed.
A demineralization plant is mainly required for
boiler feed purposes. This is because a small quantity of the circulating water
is recycled in the process. The DM plant consists of a cations and anions
exchange unit followed by the mixed bed unit.
The demineralization water is free of minerals,
so there is nothing to buffer the pH. Over time water absorbs carbon dioxide
[C02] from the air to form carbonic acid, which drops the pH. To prevent this,
you must prevent the water from coming in contact with the air by using a
nitrogen blanket.
Demineralized water without further enrichment
is not appropriate for drinking purposes. According to the WHO report drinking
demineralized water may lead to various health issues if consumed longer.
