Title: Water purification
IPC: C02F1/00
Filed: 1964-05-26
Abstract: 1,057,445. Production of potable water from saline water. B. R. BODELL. May 26, 1964 [June 3, 1963], No. 21692/64. Heading B1B. Potable water is produced from saline water by passing the saline water through heater 26 and inlet 18 into tank 12 where the warm salt water, e.g. at a temperature of 135‹F., flows over vapour-permeable tubular members 14 through which air is being passed by blower 46; water-vapour passes inwardly through the walls of the tubular members and the mixture of air and water-vapour leaving the ends of the tubes flows via a header and conduit' 50 into condenser 16. Potable water is collected in containers 52. The tubular members 14 may be made of silicone rubber, the tubing having an internal and external diameter of 0.012 and 0.025 inches, respectively. The tubular members are advantageously loosely configurated between the inlet and outlet headers, so that the tubes float freely in the saline water and respond readily to the currents in the saline water. Concentrated saline water leaves tank 12 via outlet 20 and part of it is discharged through line 34, make-up saline water being introduced through line 32. The mixture of concentrated and make-up saline water is drawn through heater 26 and then pumped to the inlet 18 of the tank 12. Heater 26 may be supplied with heat-transfer fluid, or it may be supplied with heat from a solar boiler.
