There are a few different methods of water purification repairs: 1. Reverse Osmosis Filter: This is a filter that uses pressure to push water through a semi-permeable membrane, which removes particles, dissolved ions, and organic molecules from the water. 2. UV Light Treatment: This method uses ultraviolet light to kill bacteria, viruses, and other microorganisms in the water. 3. Activated Carbon Filter: This type of filter uses activated carbon to remove chlorine, pesticides, and other organic chemicals from the water. 4. distillation: In distillation, the purified water is boiled and the vapor is then condensed back into liquid form; this method kills any microorganisms present in the water.

The three most common methods of water purification repairs are ultraviolet light, ozone gas, and chlorine. Ultraviolet light is a type of electromagnetic radiation that is used to kill microorganisms in water. It is a very effective method of purifying water, but it can only be used on clear water and it cannot be used on water that contains dissolved solids. Ozone gas is a form of oxygen that is created when an electric current passes through air. Ozone gas kills bacteria and viruses in water and it also removes chlorine from the water. However, ozone gas is a very unstable molecule and it will quickly revert back to regular oxygen after being added to the water.
