Abstract: THE INVENTION RELATES TO A METHOD FOR CONVERTING STRONGBASE ANION EXCHANGE RESINS FROM THE MONOVALENT ANION FORM TO THE HYDROXIDE FORM. A SOLUTION OF POLYVALENT ANIONS IS FIRST PASSED THROUGH THE RESIN TO DISPLACE THE MONOVALENT ANIONS. A SOLUTION OF ALKALI METAL HYDROXIDE IS THEN PASSED THROUGH THE RESIN TO CONVERT IT TO THE HYDROXIDE FORM, AND TO PRODUCE AN EFFLUENT SOLUTION OF HYDROXIDE IONS AND POLYVALENT ANIONS. THIS EFFLUENT SOLUTION IS THEN NEUTRALIZED WITH AN ACID CONTAINING POLYVALENT ANIONS, AND THE NEUTRALIZED SOLUTION IS PASSED THROUGH A SECOND BATCH OF RESIN IN THE MONOVALENT ANION FORM. IN THE PREFERRED EMBODIMENT, A PORTION OF THE EFFLUENT IS RETAINED WITHOUT NEUTRALIZATION AND IS DELIVERED TO THE SECOND BATCH OF RESIN AFTER THE NEUTRALIZED EFFLUENT TO PERFORM A PORTION OF THE HYDROXIDE REGENERATION.
Abstract translation: 1339788转换阴离子交换树脂ECODYNE CORP 1971年4月19日[1970年4月20日] 26264/71标题C3P [也在B1部分具有季铵活性基团的强碱阴离子交换树脂从一价阴离子形式（氢氧化物除外）转化为 氢氧化物形式通过使多价阴离子的水源通过第一批树脂以用多价阴离子从树脂中取代一价阴离子; 随后将碱金属氢氧化物水溶液通过树脂将树脂转化为氢氧化物形式，并制备含有氢氧根阴离子和多价阴离子的含水流出物溶液; 用含有多价阴离子源的酸中和至少一部分流出物溶液以形成中和的多价阴离子源; 并使中和源以一价阴离子形式通过第二批树脂以从其中置换一价阴离子。 “一价阴离子形式”是指氢氧化物形式以外的树脂形式。 “中和源”仅比排出液更酸性，并且可以是酸性，中性或甚至碱性。 合适的树脂是通过使叔胺与单乙烯基芳族烃和二乙烯基芳族烃的卤代甲基化交联共聚物反应而制备的树脂， 苯乙烯和二乙烯基苯的共聚物与或不与乙基乙烯基苯。 其它合适的树脂是叔胺与卤代烷基化，优选氯甲基化的乙烯基芳族化合物的共聚物的反应产物，例如乙烯基芳族化合物。 苯乙烯或乙烯基茴香醚和少量的聚烯烃化合物，例如， 二乙烯基苯，异戊二烯，丁二烯或三乙烯基苯。 在该实施例中使用氢氧化钠，硫酸钠和硫酸。

Abstract: IN A CONVENTIONAL CONTINUOUS COUNTERCURRENT ION EXCHANGE RESIN SYSTEMS, WHEREIN THE REGENERATION TANK HAS AN UPPER RESIN INLET, AN UPPER LIQUID OUTLET, A REGENERANT INLET BELOW THE LIQUID OUTLET, SEPARATION LIQUID INLET MEANS BELOW THE REGENERANT INLET, AND A LOWER RESIN OUTLET BELOW THE SEPARATION LIQUID INLET, A METHOD FOR TRANSFERRING RESIN IS PROVIDED WHICH INSURES A CONTINUOUS UPFLOW DURING THE INTRODUCTION OF REGENERANT. THE TANK IS FILLED WITH RESIN, REGENERANT IS INTRODUCED AT THE REGENERANT INLET, AND A SEPARATION LIQUID AND SUPPLEMENTAL SEPARATION LIQUID ARE INTRODUCED AT THE SEPARATION LIQUID INLET MEANS TO PRESSURIZE THE TANK AND COMPACT THE RESIN OUT THROUGH THE RESIN OUTLET. THE INTRODUCTION OF SUPPLEMENTAL SEPARATION LIQUID AND THE REMOVAL OF RESIN FROM THE TANK AND TERMINATED AT ABOUT THE SAME TIME. THE INVENTION ALSO PROVIDES APPARATUS FOR CARRYING OUT THE METHOD, AND COMPRISING SUPPLEMENTAL SEPARATION LIQUID INLET MEANS COMMUNICATING WITH THE REGENERATION TANK BELOW THE REGENERANT INLET, AND HAVING VALVE MEANS THEREON.

Abstract: A liquid precoat filter has a multitude of elongated replaceable filter elements that have one of their ends supported on tubes that project upwardly from a tube sheet. The individual filter elements are releasably connected to the tubes by couplings that permit a spring clip to lock under shoulders when the filter element is pushed down; the spring clip is released when the filter element is rotated about one-quarter of a turn. A sliding seal prevents leakage between the filter elements and their support tubes.

Abstract: A liquid precoat filter has a multitude of elongated replaceable filter elements that have one of their ends supported on tubes that project upwardly from a tube sheet. A multi-component, spring-biased, sliding seal prevents leakage between the filter elements and their support tubes. Externally engageable connectors are used to releasably fasten the filter elements to their tubes.

Abstract: A liquid distribution pipe in liquid treatment apparatus is divided into two separate liquid distribution sections. Each pipe section fits into a separate nozzle on the surface of the apparatus and is independent of the other pipe section. Each section of liquid distribution pipe can be isolated from all other sections, and can supply or withdraw liquid from the apparatus independent of the other sections.
