DM Water Plant Manufacturers In Mumbai | Swjal Process Pvt Ltd

Swjal Process Pvt Ltd is a leading DM Water Plant Manufacturers in Mumbai, offering customized and reliable demineralized water treatment systems for pharmaceutical, biotechnology, chemical, food, power and industrial applications.

The configuration of a DM Water Plant depends on raw water quality and the required final water quality. A typical system follows several important treatment stages.

1. Raw Water Pretreatment

Before demineralization, raw water normally undergoes pretreatment to reduce suspended solids, turbidity, chlorine, hardness, and other contaminants.

Depending on the feed-water characteristics, pretreatment may include multimedia filtration, activated carbon filtration, softening, micron filtration, and chemical dosing.

Effective pretreatment is important because it protects ion exchange resins and improves the overall efficiency and operating life of the DM Plant.

2. Cation Exchange

After pretreatment, water enters the cation exchange unit.

The cation resin removes positively charged ions such as:

  • Calcium
  • Magnesium
  • Sodium
  • Iron

These ions are exchanged with hydrogen ions. This significantly reduces the concentration of dissolved cations in the water.

3. Anion Exchange

The water then passes through the anion exchange unit. The anion resin removes negatively charged ions such as:
