FIELD: chemical and petrochemical industries. SUBSTANCE: method provides for feeding of liquid mediums in working canals of membrane member concentration of delaying components on membrane under action of pressures difference of permeate and concentrate, following membrane regeneration, that is carried out with working canals filled with concentrate. Canals are communicating with atmosphere in two stages, at first of which washing solution is introduced under membrane, and at second stage introduced washing solution is kept under excessive pressure of 0.2 0.6 m of liquid column within 1.5
8 hours. In the case washing solution has, mass sodium hydroxide 2 4; sintanol ДС-10 0.3 0.6; trisodium phosphate 0.2 - 0.4; permeate balance. EFFECT: high degree of liquid mediums separation. 1 dwg
