FIELD: process engineering.
SUBSTANCE: invention relates to production of deep-dehydrated water and may be used in heat and power engineering, ferrous metallurgy, chemical and petrochemical industries. Proposed method comprises pre-dehydration of initial water by sequential forcing of water through H-cation filter with strong-acid cation and OH-anion filter with strongly basic anion to obtain water carbonate content Ic io less than 2 (mg-eq/dm3)2, additional deep dehydration of water obtained at first step that is forced through OH-anion filter with strongly basic anion and H-cation filter with strong-acid cation.
EFFECT: water with specific resistance of up to 18 MOhm·cm at 20°C without using decarboniser and combined-effect filter, reduced production costs.
