Abstract: A multi-stage still is disclosed having particular utility in the desalination of water. The still comprises an array of alternating vapor impermeable and vapor permeable stacked membranes in laminar relation. Thus, each permeable membrane is sandwiched between a pair of impermeable membranes which form discrete channels on opposite sides of the permeable membrane for conducting distilland and distillate flow. The impermeable membranes are corrugated with their respective corrugations alternately canted in opposite directions with respect to the direction of fluid flow to prevent nesting of the impermeable membranes. Such opposite canting of the corrugations of alternate impermeable membranes functions to preserve the general direction of fluid flow.

Abstract: An electrolytic heater especially adapted to deaerate water by a process in which water is heated to form steam and is counterflowed against the rising steam to strip air from the water. The heater includes an open container divided by a perforated wall into upper and lower chambers and electrodes located in the lower chamber. Water is introduced into the upper chamber, passes through the openings in the wall to the lower chamber where it is heated electrolytically to form steam and from which deaerated water is withdrawn. Steam and water are required to flow in opposite directions through the same openings in the dividing wall so that the flow of each is an inverse function of the other and a balance will be reached automatically limiting the liquid level in the lower chamber and the rate of steam generation resulting from current flow between electrodes.

Abstract: A distillation system incorporating a multiple stage still comprising microporous membranes in which heated and deaerated feed liquid is utilized, in part, as distilland, and in part, as a heating liquid for transferring heat to the distilland within the still to generate a thermal gradient and effect heat transfer required to produce distillate from the distilland. The feed liquid employed for heating is returned to a deaerator heater where it is combined with additional feed liquid to replace the distillate and effluent distilland liquid. Heat is transferred from the effluent and distillate to the additional feed liquid prior to introduction thereof into the deaerator heater.

Abstract: A still comprising a distillation unit formed by arranging microporous membranes and corrugated, impermeable films in alternating stacked relation together with adhesive sealing elements located between adjacent membranes and films and a spacer located between two stacks of membranes and films, to form channels for liquids. The assembly of membranes, films, sealing elements and spacer is subjected to heat and pressure to bond the sealing elements to the membranes, films and spacer, and holes are drilled through the unit to form conduits for feeding liquids to and from selected channels between adjacent membranes and films. The unit is then located together with sealing elements between the walls of two complimentary housing sections which are sealed to one another to form a housing enclosing the unit and subjected to heat and pressure to bond the unit to the walls of the housing to form additional liquid channels. The corners of the distillation unit are sealed to the corners of the housing to form chambers for receiving and distributing feed, heating, and coolant liquids. All of the components are designed to be fabricated or formed of polymeric sheet materials and connections for the flow of liquids are made to the conduits within the still (housing) by way of nipples secured to the housing and/or liquid conduits pressed into liquid-tight engagement with the housing. One surface of each member is corrugated to prevent blockage of the channels for feed liquid and the walls of the housing as well as the spacer are corrugated to provide channels for heating and coolant liquids.

Abstract: 1,096,678. Multiple effect distillation apparatus; desalination of water. PACTIDE CORPORATION. Nov. 18, 1966 [Nov. 26, 1965; May 26, 1966], No. 51715/66. Addition to 1,096,677. Heading B1B. A multiple effect distillation apparatus comprises porous membranes 10, which are permeable to the vapour of the liquid being distilled but impermeable to the liquid itself, arranged in alternate stacked relationship with corrugated heat-conductive barriers 12, which are impermeable to both liquid and vapour. The liquid to be distilled, e.g. salt water, flows through the channels formed by the underside of each porous member 10 and the upper surface of the adjacent corrugated barrier 12, the flow being in the direction of the corrugations. Distillate liquid, potable water, flows through the other channels. A gasket 26, in the form of a frame, is disposed between each porous member and the adjacent barrier; and the whole assembly is clamped between header plates. The lower header plate 16 is supplied with heat, e.g. by solar energy; and partial vaporization of the distilland in the lowermost channel takes place, the vapour diffusing through the porous membrane and condensing in the distillate liquid flowing through the channel above. The heat of condensation is given up through the heat-conductive barrier to the distilland in the third channel, this multiple-effect operation being repeated in the remaining channels. The upper header plate 14 is cooled, e.g. by feed liquid. The feed liquid is supplied to channel 46 in manifold 40, from which the feed flows through alternate channels of the still, the unevaporated liquid being collected in and discharged from manifold 42. The distillate liquid flows in the opposite direction through the other channels, and is withdrawn through channel 48 in manifold 40. The heat-conductive barriers 12 may be made of copper, aluminium, polyvinylidene fluoride, or a polycarbonate. The porous membranes 10 may be made of polyvinyl chloride, a cellulose derivative, nylon, or polytetrafluorethylene.
