FIELD: food industry.
SUBSTANCE: source water is demineralized to pH=6.3-6.9, after that K2SO4 is added to the demineralised water and MgCb in an amount providing the content of cations K+=36-42 mg/l, Mg2+=18-21 mg/l, and anions SO4 2-=44-52 mg/l, Cl-=53-60 mg/l. When preparing mineralised water of winter destination the demineralisation is carried out up to pH=6.7-6.9, and these salts are added in a quantity providing the content of cations K+=36-42 mg/l, Mg2+=18-21 mg/l and anions SO4 2-=44-52 mg/l, Cl-=53-60 mg/l. When preparing mineralised water of spring and autumn destination demineralisation is carried out up to pH=6.5-6.7, and these salts are added in a quantity providing the content of cations K+=52-60 mg/l, Mg2+=26-30 mg/l and anions SO4 2-=64-74 mg/l, Cl-=76-86 mg/l. When preparing mineralised water of summer destination demineralisation is carried out up to pH=6.3-6.5, and these salts are added in a quantity that provides the content of cations K+=88-100 mg/l, Mg2+=44-50 mg/l and anions SO4 2-=108-123 mg/l, Cl-=128-146 mg/l. This reduces water hardness: hardness of drinking water of winter destination is 1.5-1.75 meq./l, spring-autumn destination is 2.2-2.5 meq./l and summer destination is 3.7-4.2 meq./l., and also use it for prevention of homeostasis.
EFFECT: invention reduces water hardness.
