Methods of Water Purification
1. Introduction:
Water purification is the process of making water clean for human consumption. The main purpose of water purification is to remove impurities such as dirt, dust, chemicals, and microorganisms from water. There are several methods of water purification, including reverse osmosis, distillation, and chlorination.
2. Traditional water purification methods:
There are several traditional methods of water purification, including solar water disinfection, boiling, and chlorination.
2. 1 Solar water disinfection:
Solar water disinfection (SODIS) is a type of water purification that uses sunlight to kill bacteria and viruses in water. This method is effective for treating small volumes of water, such as those used for drinking or cooking. To use this method, water must be placed in a clear container and exposed to direct sunlight for at least six hours.
2. 2 Boiling:
Boiling is another traditional method of water purification. This method kills bacteria and viruses by heating the water to a temperature of 100 degrees Celsius. Boiled water should be left to cool before drinking.
2. 3 Chlorination:
Chlorination is a process that uses chlorine to kill bacteria and viruses in water. This method is often used to treat large volumes of water, such as those used in public swimming pools and drinking water supplies.
3. Modern water purification methods:
There are several modern methods of water purification, including reverse osmosis, distillation, and alkaline water filtration.
3. 1 Reverse osmosis:
Reverse osmosis is a type of water filtration that uses pressure to force water through a semipermeable membrane. This process removes impurities from the water, making it clean and safe to drink.
3. 2 Water distillation:
Water distillation is a process that involves boiling water and collecting the resulting steam. This steam is then condensed and cooled, resulting in distilled water that is free from impurities.
3. 3 Alkaline Water Filtration:
Alkaline Water Filtration is a type of water purification that uses an ion exchange process to remove impurities from the water. This process results in clean, safe, and healthy drinking alkaline waters which have a pH level of 8 or above. 4 Conclusion: There are several methods of water purification, including reverse osmosis, distillation, chlorination, and alkaline ion exchange filtration.Each method has its own advantages and disadvantages, so it is important to choose the right method for your specific needs. reverse osmosis systems are typically more expensive than other methods
