[Also in Division B5] Apparatus for parating solvents from solution, especially for the desalination of a water, compris a plate 10 having a bore 16 and counterbore 17 in which is received a mipermeable membrane 20, and a plate 11 having a recess 21 of the same diameter as counterbore 17 so that the spaces when matched form a cylindrical opening. Plate 10 has an annular groove 12 in which is fitted a aling ring 13, and plate 11 has a flange 15 fitting a shoulder on plate 10. A paper filter or spacer member 22 is fitted between the membrane 20 and a porous disc 24 and spacer member 25. Plate 10 has an annular groove 27 which receives a ring 28 which als the edges of the membrane. Feed water is supplied at 31 and pass through channel 32 which has a branch 33 leading to rervoir 16. Passage 32 also communicates directly with membrane 20. 35 is an outlet passage terminating at 36. Demineralized water filters through membrane 20 into the central circular space and to the porous plate 24, and drains out at 37. Salt solution from 41 is pressurized by pump 44 and pass to the apparatus 40. Desalinated water is removed

nprculated via pump 45. An apparatus suitable for larger scale working is shown in Fig. 4. The cell is enclod by plates 55 and 60 having recess 61 and 62. Plates 65 and 74 are stainless steel collector plates parated from 55 and 60 by mipermeable membranes 66 and 76, held in place by aling rings 70, 73. Additional mipermeable membranes A and 75, held by aling ring 72, parate the plates from the intermediate cell 71. In operation water enters 61 and pass through channel 69 to cell 71. Desalinated water is collected from the ba of plates 65 and 74. For details of the preparation of the mipermeable membrane, e Division B5. The paration of virus and proteins from solution is also referred to.
