Impure water can be purified through several methods, including filtration, boiling, and chemical disinfection. Filtration removes physical contaminants using materials like sand or activated carbon. Boiling kills pathogens by heating water to a high temperature, while chemical disinfection, using substances like chlorine or iodine, effectively eliminates harmful microorganisms. For more comprehensive purification, a combination of these methods is often recommended.
The refining of the impure salt involve filtration of the water solution and the purification by repeated processes of crystallization/recrystallization.
The pure form of water is distilled water, which has been purified to remove impurities such as minerals, salts, and contaminants. Impure water can contain various substances like minerals, microorganisms, chemicals, and pollutants, making it unsafe for consumption. The presence of impurities in water can affect its taste, smell, and overall quality, making it essential to purify water for various uses.
You can buy special water filters that will make impure water suitable to be drunk without having to boil the water first or the need to add chemicals. I have seen such a device used in a very isolated Youth Hostel Association hostel. So a search on the internet should produce available products.
