Marine Water Mineralizer
Publish Time: 2026-09-07 Origin: Site
The distilled water produced by a vessel‘s fresh water generator is extremely pure, but long-term consumption of this “deionized water” is not ideal for human health – it lacks essential minerals and trace elements, has poor taste, and is corrosive to piping and equipment.
How can distilled water be transformed into high-quality fresh water that crew members are willing to drink and that is beneficial to health? The Deyuan Marine Water Mineralizer is the critical solution to this challenge.
Product Overview:
The Deyuan Marine Water Mineralizer is a drinking water post-treatment device specially designed for vessels and offshore platforms. Installed downstream of the fresh water generator, it adds essential minerals to the pure water, making it compliant with drinking water standards.
The product is designed in accordance with CB 1193-1988 “Shipboard Drinking Water Mineralizer” industry standard, applicable to the mineralization of fresh water produced by desalination units on vessels and offshore platforms, as well as other drinking water solid mineralization applications.
Why Mineralize?
Issue | Description |
Lack of minerals | Distilled water contains no calcium, magnesium or other essential minerals – not ideal for health |
Low pH value | Distilled water is slightly acidic – may affect the body‘s acid-base balance |
Poor taste | Flat taste – crew may avoid drinking it and purchase bottled water instead |
Corrosive | Deionized water tends to corrode metal piping and equipment |
Working Principle:
Deyuan Marine mineralizers employ a solid media dissolution-type mineralization process. Distilled water enters at the top and flows downward through dolomite mineralizing media.
Dolomite is a natural carbonate mineral (chemical composition: CaMg(CO₃)₂). As water flows through the dolomite bed, it slowly dissolves, releasing calcium ions (Ca²⁺) and magnesium ions (Mg²⁺) while adjusting the pH to neutral or slightly alkaline.
After Mineralization, The Water Features:
*Contains essential minerals (calcium, magnesium).
*pH adjusted to 7.0–8.0 (neutral to slightly alkaline).
*Pleasant taste – suitable for long-term consumption.
*Reduced corrosivity – protects piping and equipment.
