FIELD: chemistry.
SUBSTANCE: invention relates to technologies of purification of water from natural springs for their further application as initial water for obtaining vapour in processes of steam or vapour-oxygen conversion of hydrocarbon gases (synthesis-gas production). Installation for preparation of desalinated water contains successively connected heat exchanger for heating initial water, unit of preliminary clarification, unit of ultrafiltration, unit of ultraviolet decontamination, unit of filters with filtration degree not more than 5 mcm and unit of two-step reverse osmosis.
EFFECT: invention ensures increase of service term of ultrafiltration and reverse osmosis membranes, water decontamination.
