摘要： An improved spiral wound reverse osmosis or ultrafiltration membrane cartridge has the inner end and side areas of a permeate transfer leaf sealingly attached to its central collection tube surface, with sealing adhesive applied as band areas near each side edge of the proximate transfer leaf surface in amount in excess of the amount to substantially fill a pair of circumferential grooves in the collection tube when the assembly, including the permeate transfer leaf is spirally wound around it. The adhesive seal is preferably cured at room temperature with the cartridge standing on one of its ends for a period of about 12 to 24 hours. In an alternative embodiment, resilient O rings may be seated in the collector tube grooves, and an additional pair of grooves within the side band areas may also be filled with adhesive.

摘要： An improvement in a membrane cartridge for insertion into a pressure-resistant container and having a central passageway holding a permeate collection tube. A cartridge is formed, at least in part, by a spiral winding of a laminate leaf comprising semipermeable membrane sheet material, permeate transfer sheet material, and porous grid sheet material. An extension on the leaf of the porous grid material is of sufficient length to encompass the circumference of the cartridge when the cartridge is positioned inside the container. The cartridge may have an outer wrapping of water-soluble sheet material.

摘要： A spiral wound reverse osmosis or ultrafiltration membrane cartridge has a central collection tube fabricated from a plurality of interlocking segments; the center segments are perforated and the segment at each end is imperforate. The side edges of the cartridge membrane leaves and the permeate transfer sheet are sealingly attached to the central collection tube by circumferential bands of glue located outboard of the juncture of the imperforate end segments with adjacent perforate center segments. Substantial fabrication economies result from injection molding the center segments as identical bodies from a single die; and injection molding the end segments also as identical bodies from a single die.

摘要： A reverse osmosis system employs a tank for storing permeate under a pressure which is a portion of the pressure of feed water introduced into a pressure resistant container housing a semipermeable membrane cartridge. Control means such as an automatic valve, preferably of the double diaphragm type, in the line introducing feed water into the pressure resistant container closes to shut off feed water flow when the pressure in the permeate storage tank reaches a first predetermined value, less than the feed water pressure, and re-opens to re-establish feed water flow at a second predetermined pressure lower than the first or shut-off pressure. A constricted passageway device such as a venturi in the pipe or connection between a dispensing device such as a faucet and the permeate storage tank has its throat communicating with the sensing conduit for actuating the feed water control valve. When the dispensing faucet is opened, flow of permeate through the venturi creates an amplified and drastically reduced pressure in the sensing conduit, and applies a servo or magnified actuation force to the valve in the re-open end of its control range.

摘要： A process for recovery of fresh water by reverse osmosis from high salt content feed, such as sea water, comprises treating the feed water in an initial stage at relatively low pressure (between about 300 and 550 psi) employing a loose semipermeable membrane, to produce an intermediate product water containing one-fourth to one-half the TDS (total dissolved solids) content of the original feed water. The intermediate product water is treated in a subsequent stage also at a relatively low pressure (between about 300 and 550 psi) employing a tight semipermeable membrane, to produce a fresh product water containing less than 2,000 ppm TDS, and preferably a potable water containing less than 1,000 ppm TDS.

摘要： An over-the-counter, free-standing, water purification system including a pressure vessel that encloses a reverse-osmosis separator. Tap water at a pressure of between approximately 20 and 100 psig is introduced into the pressure vessel and a portion of the water is forced through the reverse-osmosis separator, while the remaining water is discharged from the pressure vessel along with the pollutants that are too large to penetrate the membrane of the reverse-osmosis separator. The product water passes through the reverse-osmosis separator at a rate of between approximately 5 to 100 milliliters per minute and is then post-filtered at a slow rate through a large amount of activated carbon, between approximately 10 and 1,000 grams, contained within the housing for the purification system. The product water has a contact time of residence time with the activated carbon of between approximately 15 to 30 minutes, which ensures that any odor, taste, color organic waste or chlorine passing through the reverse-osmosis separator are adsorbed by the activated carbon. After passing through the activated carbon, the purified water is discharged from the pressure vessel into, e.g., a container in which it is stored until needed.
