Demineralised Water

Available in 250ml, 500ml, 1L, 5L and 25L

Demineralised water, also known as deionised water or purified water, is a type of water that has undergone a process to remove impurities and minerals. These impurities include elements like calcium, magnesium, iron, salts, and other mineral particles, resulting in water that has a very low mineral content.

 Demineralised water has numerous applications across different industries. It is commonly used in laboratories, pharmaceutical settings for equipment sterilisation, manufacturing drugs, and preparing medical solutions. And used in the automotive industry for car battery maintenance, engine cooling systems, and windshield washer fluids,

offering an essential solution where ultra-pure water is necessary to meet stringent quality standards and maintain optimal performance.


Top uses for Demineralised Water:

Industrial Processes: This type of water is used in various industrial processes such as power generation, chemical manufacturing, pharmaceutical production, electronics manufacturing, and food processing.


Steam Generation: It is commonly used in boilers and steam generators to prevent mineral scale build-up, corrosion, and ensure efficient heat transfer.


 Cooling Systems: This type of water is ideal for cooling systems in power plants, car engines, and other machinery. It helps prevent mineral deposits and scaling and enhances the efficiency of the cooling process.


Laboratory Applications: Due to its purity, This water is a vital component in numerous laboratory experiments, research, medical equipment, and analytical processes.


Automotive Batteries: This type of water is used to fill and maintain the electrolyte levels in automotive batteries. It helps improve the battery’s performance and extends its lifespan.


Cosmetics and Personal Care Products: Many cosmetics and personal care products, such as shampoos, conditioners, and skincare products, require demineralised water as a base ingredient to ensure stability and quality.


Pharmaceuticals: This water is essential in pharmaceutical manufacturing for the preparation of drug formulations, cleaning equipment, and meeting strict regulatory requirements for drug purity and safety.


Electroplating and Surface Finishing: This type of water is commonly used in electroplating and surface finishing industries to achieve high-quality finishes, prevent contaminants, and ensure even coating and adhesion.


Concrete Mixing: Demineralised water is commonly used in concrete mixing to minimize mineral deposits, resulting in stronger and more durable structures.


Irrigation and Hydroponics: This water is used in irrigation systems and hydroponic setups to prevent clogging and mineral build-up in pipes, hoses, and grow media, ensuring optimal plant growth and nutrient absorption.



Frequently asked questions:
  1. What is PureChem demineralised water?

Demineralised water is water that has undergone a process called demineralisation, where most of its mineral ions, such as calcium and magnesium, have been removed.


  1. How is this water produced?

Demineralised water is typically produced through various techniques like distillation, ion exchange, reverse osmosis, or electrodialysis. These methods remove impurities and mineral ions, resulting in water with very low mineral content.


  1. Why is this water so commonly used?

Demineralised water is often used in industries where the presence of minerals could be detrimental or cause issues, such as in medical operations, laboratory experiments, industrial machinery, or cooling systems where mineral build-up can cause damage or inefficiency.


  1. Is demineralised water safe to drink?

While demineralized water is safe to consume in small amounts, it is not recommended as the primary drinking water source for long-term use. Consuming water without beneficial minerals may lead to mineral deficiencies over time. It is advisable to have a balanced intake of both mineral-rich and demineralised water.


  1. Can demineralised water be used in household appliances, like steam irons or humidifiers?

Yes, This water can be used in household appliances, especially those prone to mineral build up. Using demineralized water in steam irons, humidifiers, or similar devices helps prevent mineral deposits and extends the lifespan of the appliance.


  1. How can demineralised water be re-mineralised?

This water can be re-mineralised by adding trace minerals, such as calcium, magnesium, or potassium, in specific proportions to make it suitable for consumption. This process is often done in the bottled water industry to improve taste and health benefits.


  1. Is demineralised water corrosive?

Demineralised water, in its pure form, can be corrosive to certain materials. The absence of minerals makes it more aggressive towards metals and may lead to corrosion if stored or transported in metal containers for extended periods. It is recommended to use demineralized water in appropriate containers to minimize the risk of corrosion.


  1. Can demineralised water be used for car batteries?

Yes, PureChem demineralised water is commonly used to top up car batteries. The removal of impurities and minerals reduces the risk of chemical reactions and helps optimize the performance and longevity of the battery.


  1. Does demineralised water conduct electricity?

PureChem demineralised water has a very low conductivity due to the absence of ions that facilitate electrical flow. While it may not conduct electricity as effectively as tap water or mineral-rich water, it can still conduct electricity to some extent, caution should be taken when dealing with electrical equipment and demineralised water.


  1. How should this water be stored?

Demineralised water should ideally be stored in clean, non-reactive containers made of materials like glass or food-grade plastic. This helps maintain its purity by preventing any potential contamination from reactive substances or chemicals.
