• W2000542166 abstract "Abstract Techniques were developed for precoating ceramic tubes with a 0.006-in. layer of fine particle size ZrO 2 powder; dynamic membranes formed on the precoated porous surfaces possessed fluxes of 95 to 100 gal/ft 2 ·day and rejections of 85 to 90% for 0.05 M NaCl compared with values of 20 gal/ft 2 ·day and 40 to 60% obtained with nonprecoated tubes. These ceramic tubes were then incorporated in a seven-tube bundle with a total area of 6 ft 2 . A module consisted of two of these bundles fitted into a pressure housing fabricated from standard 2-in. pipe; this module then possessed a flux density of 4453 gal/day per cubic ft. compared with values of 1350 and 3000 gal/day per cubic ft for hollow fine fiber and spiral wrap modules, respectively (1) . Since 1971 the flux density for hollow fine fibers has been 13,000–18,000. Similarly, the flux of membranes utilized in spiral wound or tubular systems has also increased very significantly, but not by an order of magnitude. The procedure developed for forming dynamic membranes on the ceramic tube modules consists of the following steps: 1. Adjust the pH of the 0.05 M NaCl feed solution to pH = 4 and add sufficient hydrous zirconium oxide to give a concentration of 50 mg/liter. 2. Within one-half to one hour after introduction of the feed to the system at a pressure of 1000 psig and a velocity of 30 ft/sec, either the flux will be of the order of 1000 gal/ft 2 ·day or the rejection will be 35 %; whichever value occurs first is not critical. At that time adjust the pH of the flowing stream to 2 and add sufficient PAA to give a concentration of 50 mg/liter. 3. Approximately one hour after addition of the PAA begin neutralization of the flowing stream with NaOH solution. The pH should be increased in steps over an interval of one to two hours until the circulating stream is near neutral. At this time the dynamic membrane should have a rejection of 85 to 90% and a flux of 95 to 100 gal/ft 2 ·day when the feed is 0.05 M NaCl. The velocity can then be reduced to 15 ft/sec with little loss in flux or rejection." @default.
