Purified Water is a term used to describe water that has been treated to remove impurities and contaminants. The term "purified" indicates that the water has undergone purification processes to remove impurities such as particles, bacteria, viruses, chlorine, minerals, and other chemical substances. These processes can include filtration, distillation, reverse osmosis, or other treatment methods.

Industrial Chemical Synthesis

Treatment and Purification. The water purification process can include various steps such as filtration, reverse osmosis, distillation, or deionization, depending on the quality of the starting water and the required level of purity.

• Filtration: Removes suspended particles and sediments.
• Reverse Osmosis: Removes dissolved minerals and organic impurities.
• Distillation: Evaporates and then condenses water to remove impurities and minerals.
• Deionization: Removes ions like sodium, calcium, and iron, making the water chemically pure.

Quality Control. After purification, the water undergoes rigorous quality testing to ensure it meets specific standards, such as pharmaceutical or laboratory use standards.
