title: [Preparation of water at kidney centers using separating counterosmosis equipment].
abstract: A water treatment AKBA-I unit intended for the renal centers was tried. The unit includes a clarifier, an adsorber, a softener, a reflux osmotic separator and electronic systems for the control of hydrodynamic processes. The trials demonstrated the unit to be highly effective as regards the removal from water of salts of hardness, of iron, potassium, oxidizable substances and active chlorine. The pH value of the filtrate (7.1-7.4) appeared to meet the requirements made during the preparation of a dialyzing solution. The concentration of sodium ions in the filtrate was 0.75 mg.eq/l, which did not influence the concentration of sodium ions in the dailyzing solution during its preparation from dry concentrate. During operation of the unit, the selectivity of the APO membrane in the operating mode was defined. It amounted to 85%.
