Abstract

The invention relates to a method of using anhydrous monosodium phosphate having formula NaH2PO4 in aqueous solution as a chemical additive for water chlorinated with Javelle water in order to optimise the disinfectant action thereof, to provide scale preventive and anticorrosive properties and to break down mineral and/or organic deposits.
