Demineralization (DM Plant) is the process of removing mineral salts from Water by using the ion exchange process. Fluid Systems Manufacturing a Wide range of custom-built Demineralized Water plant [DM Plant] in India for industrial process water applications, with inherent design to conserve water and save costs.
DM (demineralized) water plants are methods used to carry out industrial water treatment. To be extra precise, the DM plant remove dissolved solids or minerals from procedure streams and feed water. These plants remove minerals using any one of the following techniques:
- Membrane filtration (reverse osmosis or nanofiltration)
- Or other technologies
Demineralized water or deionised water is water devoid of its mineral ions. Water in its natural form classically contains mineral ions like anions (sulphate, chloride, nitrate, etc.) and cations (iron, calcium, sodium, copper, etc.)
The main drive for which a DM plant is used is preventing metal oxidation and scale formation.

Dm Plant Process
As mentioned above, the salts and minerals present in water carry negatively charged ions called anions and definitely charged ions called cations. Both these types get attracted by their counterions i.e. ions carrying the opposite charge.
These plants feature an IX column containing resins that contain of plastic beads. During the process of demineralization, the ionic functional group gets attached to these beads. These are functional groups that work by holding the ions carrying the conflicting charge loosely through a process called mutual electrostatic attraction.
When an ion-exchange cycle is underway, water containing dissolved ions comes in interaction with the resin. Ions present in the solution exchange their place with those present on the beads. These ions remain attached to the functional groups of the resins even when the resulting liquid gets drained away. Ion exchange occurs when an ion possesses a greater affinity towards a functional group than the ions the group previously carries. The type of ionic contaminants found in the group will decide whether the process would need cationic resins or anionic resins.
In most ion-exchange reactions, the exchange substitutes the contaminant ions with less objectionable ions. For instance, the ion exchange sodium softening procedure is carried out to eliminate hardness ions like Mg2+ or Ca2+ from the solution and replace them with less harmful sodium ions or Na+. Once the procedure is over, the solution will have little or no hardness but will have a higher concentration of Na+.
The above changes are acceptable for certain applications. However, some procedures require almost 100% removal of the dissolved solids. This makes DM plants such significant additions to facilities requiring complete elimination of these unwanted solids. A DM plant interactions cations in feed water with hydrogen ions and anions get exchanged with hydroxyl ions. This results in the formation of water. Most plants come with a mixed bed or two-bed configuration.
Every DM plant works based on a common principle. They work to eliminate minerals and other contaminants from water using the ion exchange method. The purity of water would depend on the kind of DM water plant you are using.
Application Of Dm Plants
More and more businesses have started to use DM plants to prepare a hefty resource of demineralized water. However, some businesses have been using these units since their discovery. These are businesses that need a high level of water purity. Here are some examples:
- Industries that need the use of makeup water or feed for operating high-pressure boilers
- Food & beverage industries (they prepare rinse water using these plants)
- Electronic goods manufacturers
Dm Plant Specifications
Some of the most notable conditions of top DM plant models include:
- Automatic time-based regeneration
- DM resin of the highest quality
- The user-friendly inline configuration that enables informal installation and upkeep
- A combination of bottom group and highest distribution systems crafted out of laser-cut strainers embedded on strainer plates lined with rubber
Advantages Of Dm Plants
If you use a unit made by a top DM plant manufacturer, you will enjoy the following benefits:
- The water produced by these units is of much higher quality than the regular distilled water we use.
- You will get to choose from DM plants of different sixes and boasting different specifications. There will be units designed and manufactured to be used in labs as well as units produced for large, medium, and small-scale businesses.
- The purification procedure doesn’t involve the use of any chemical. Additionally, the process also doesn’t produce any dangerous waste products.
- Most modern-day units will not need much space for storage.
- Using DM plants to demineralise water has been found to reduce the overall product price at industrial manufacturing units.
