In the process of softening water, the water softener will replace the calcium and magnesium ions in the water with sodium ions. Therefore, the sodium content in the treated water will increase. For healthy adults, moderate sodium intake will not have a significant effect on the body.

The cheapest water treatment method is 1. Boiling 2. Solar Disinfection (SODIS) The most effective water treatment method is 1. Reverse Osmosis (RO) 2. Ultraviolet (UV) Disinfection 3. Ozone Disinfection

Reverse osmosis (RO) technology is considered to be one of the most effective water treatment methods. Reverse osmosis technology uses semipermeable membranes to efficiently remove dissolved salts, organic matter and microorganisms in water, and can provide high-quality purified water.

First, it improves the production efficiency and product quality of enterprises and enhances their competitiveness; second, it saves water costs and reduces production costs; third, it meets environmental protection requirements and enhances the social responsibility image of enterprises.

The chlorination of water process refers to adding chlorine gas or other chlorides to water to make the water contain a certain concentration of chloride ions to achieve the purpose of disinfection and sterilization. In the chlorination of water process, commonly used chlorination agents include chlorine gas, sodium hypochlorite, chloramine, etc.

The most common water treatment methods include boiling, filtering, and using water treatment equipment. These methods are widely used worldwide to ensure the quality and safety of drinking water.
