Abstract: Apparatus for and method of feeding a solute into a stream of solvent at an accurately predetermined and variable rate. A solute such as an acid for treating water to prevent scale formation is disposed in a container in solid form. The interior of the container communicates with a supply of heated and deaerated distilland via a conduit blocked by a predetermined variable area microporous membrane. The heated and deaerated distilland is circulated in contact with one side of the membrane and diffuses therethrough whereby the solute dissolves therein to form a concentrated aqueous acid solution. The concentrated acid solution is permitted to diffuse back through the membrane and mix with the distilland to control the pH thereof. The solute concentration within the acid solution in the container is maintained generally constant and means are provided for indicating a change in solute concentration.

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 membrane 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.
