Description

Sodium Metabisulfite with the chemical formula (Na2S2O5) is a white compound of hydrogen, sulfur, and oxygen that is inorganic and is known to be one of the strongest chemicals in removing chlorine from water. This inorganic combination of antioxidants and disinfectants is very strong and is used not only in Water Treatment and wastewater but also in food production industries such as paper and other industries.

Application

Sodium metabisulfite acts as an Antibacterial Agent in water treatment. This material is used to clean the mass of water pipes in the Desalination plant. This substance reduces excess chlorine in the purification process and is a factor for reducing oxygen soluble in water, used for special purposes.

The use of sodium metabisulphite in water treatment can reduce the amount of excess chlorine in the water. It can also absorb O3 and reduce its amount in water. Chlorine and ozone are two oxidizing substances that destroy water if they reach the reverse osmosis process during water treatment. like PBTC

Other applications

To remove excess chlorine in drinking water and neutralize fertilizer;

To eliminate oxygen in the water and feed water boilers;

In the food industry as a preservative and preventer of food spoilage;

In the plating industry for wastewater treatment containing chromium ions;

In the leather industry to lime removal the skin;

Papermaking (for bleaching wood paste);

This combination is very suitable for use in photo printing darkrooms in photography due to its acidic and preservative properties;

In the cosmetics industry as a preservative;

As a reducing agent for purification and separation of aldehydes and ketones in the chemical industry;

As a source of SO2 production in gold cyanidation processes.
