SUBSTANCE: method includes mechanical activation by passing a water flow through a membrane system with holes with d diameter not larger than 1 mm with a ratio of a flow section to 10%, with pressure variation from 0.05 to 0.5 MPa, water alkalisation with a water ammonia solution in an amount of 0.003÷0.05 wt % and separation of an insoluble sediment from the processed water. The length of hole channel L is selected by condition L≥10d, where d is a diameter of one hole. Separation of the insoluble sediment from the processed water is performed in centrifuges of a setting type with pulsing or auger discharge of the sediment.

EFFECT: increased efficiency of the water softening process, reduction of energy consumption and reduction of concentration of an introduced alkalising solution.

SUBSTANCE: invention relates to water desalination and can be used for demineralisation of natural waters and effluents by electrodialysis in nuclear power engineering, electronic medical, pharmaceutical industries, etc. electrodialysis apparatus comprises housing accommodating anion and cation membranes arranged between electrodes to separate the housing into three chambers: anode chamber, cathode chamber and initial water chamber, initial water channel and dialysate and concentrate discharge channels. Membranes are made of plies of the fluid of different density and thickness. Note here that cation membrane density is higher than that of initial water while anion membrane density is lower than that of initial water. Anion membrane is made of plies of ethanol and toluene. Cation membrane is made of plies of nitrobenzene and glycerine with nominal thickness of each fluid membrane pile making 40-45 mm.

EFFECT: higher degree of desalination, lower labour input, higher reliability of operation.

FIELD: process engineering.

SUBSTANCE: invention relates to drier for wheel washing machine. Drier of machine (1) for washing of wheels (R) comprises first fluid feeder (40) directed to first surface (35) of wheel (R) to be dried, second fluid feeder (60) directed to wheel second surface (35') opposite said first one, first set of feed nozzles (50) arranged at said first feeder (40) and second set of feed nozzles (61) arranged at said second feeder (60). Said first and second sets of nozzles (50, 61) are levelled at first common levelling surface (P1) and second surface (P2).

EFFECT: properly directed drying airflows, removal of washing fluid from wheel surfaces.
