(Main)Chemicals used for treatment of water intended for human consumption - Antifouling for membranes – Sulfamic acid
Chemicals used for treatment of water intended for human consumption - Antifouling for membranes – Sulfamic acid
This European Standard specifies the characteristics and the requirements for sulfamic acids and salts.
Similar to antiscalants as phosphonic acids and its salts (EN 15040) and polycarboxylates and its salts (EN 15039), sulfamic acid and its salts can be used alone or in combination with others drinking water substances as antifoulants (antiscalant effect) for membranes for the treatment of water intended for human consumption.
Sulfamic acid and salts are used in mixtures with sodium hydroxide and sodium hypochlorite or other drinking water chlorine based oxidizing agents as biofilm remover especially for reverse osmosis (RO) and nanofiltration membranes to prevent biofouling by microbiological contamination. The components will not pass the membrane and are rejected to the wastewater with the concentrate. For the other components EN standards are already exist.
