DM Water related to TDS in Thermal Industry
Demineralized water is commonly used in the power industry for boiler feed water and steam generation. High-pressure boilers are needed to generate steam for turbines, which necessitates a more complex feed water treatment system to eliminate as many contaminants as feasible.
Plants that treat industrial water using demineralized water are known as demineralised water plants. The DM plant removes dissolved solids or minerals from process streams and feed water, to be more accurate. Minerals are removed by these plants using one of the following methods:
- 1. Deionisation
- 2. Distillation
- 3. Electrodialysis
- 4. Filtration using membranes (nanofiltration or reverse osmosis)
The primary function of a DM plant is to avoid metal oxidation and scale formation.
Relation to TDS (Total Dissolved Solids)
Demineralized water is defined as having a total dissolved solids concentration of 1-10 mg/L (ppm) TDS. TDS levels in spring or mineral waters, on the other hand, range from 50 to 300 mg/L.
While the term "demineralized water" appears to be harmless, is it safe to drink? Many professionals have stated unequivocally that drinking it is harmful to your health. The World Health Organization (WHO), for example, published a paper in 2004 titled "Health Risks from Drinking Demineralized Water." which stated
“It has been adequately demonstrated that consuming water of low mineral content has a negative effect on homeostasis mechanisms, compromising the mineral and water metabolism in the body.”
For the following four reasons, demineralized water is not the safest drinking water for your health:
1.It has a negative impact on several areas of human biology.
2.Does not supply critical minerals for our health
3.When used to cook, make juice, or make baby formula, it depletes meals of critical minerals.
4.Metal surfaces, such as copper and lead pipes and fittings, tanks, and even bottles, are attacked, resulting in the dissolution of metals and other pollutants into the water.
