demineralized water plant
A demineralized water plant removes minerals and impurities from water using the following key components:
1. Pre-Treatment: Filtration, coagulation, and sedimentation to remove larger particles.
2. Ion Exchange: Cation and anion resins remove dissolved minerals and salts.
3. Polishing Filters: Activated carbon removes remaining organic contaminants.
4. Post-Treatment: UV or ozone disinfection for microorganism control.
5. Storage & Distribution: Tanks for storing and distributing purified water.
A demineralized water plant is a facility designed to remove minerals and dissolved solids from water to produce demineralized (or deionized) water, which is highly purified. The water produced is typically free of dissolved salts, minerals, and other impurities that are commonly found in natural water sources.
* Main Components of a Demineralized Water Plant:
1. Pre-Treatment System:
Filtration: Removes larger particles such as sand and silt.
Coagulation & Flocculation: Chemical agents are used to clump smaller particles together, making them easier to remove.
Sedimentation: Suspended solids settle out of the water.
2. Ion Exchange System:
This is the core process for demineralizing water. It involves passing the water through cation and anion exchange resins.
Cation Exchange: Removes positively charged ions like calcium (Ca²⁺), magnesium (Mg²⁺), and sodium (Na⁺).
Anion Exchange: Removes negatively charged ions such as chloride (Cl⁻), sulfate (SO₄²⁻), and bicarbonate (HCO₃⁻).
