    • Electrodeionization apparatus for purifying water that includes a cathode, an anode, and a plurality of alternating anion permeable membranes and cation permeable membranes between the cathode and anode that define concentrating and diluting flow channels between adjacent pairs of membranes. The diluting channels include cation exchange materials and anion exchange materials that are fixed in close contacting position with respect to each other and provide conductive paths for cations and anions to the adjacent membranes and provide flow passages for water between the materials. The anion exchange materials and cation exchange materials each have a characteristic dimension that is smaller than the characteristic dimensions of the flow passages. The use of exchange materials with small dimensions and the fixed intimate contact of cation and anion exchange materials provides increased, uniform water splitting and resin regeneration, and a high rate of ion removal from the water flowing through the diluting channels compartments. An increased velocity can be provided in the diluting channels of by reintroducing a portion of the water from the diluting channel outlet to the diluting channel inlet or using flow diverters in the diluting channel to provide a tortuous path for the flowing water.
    • 用于净化水的电除去装置,其包括在阴极和阳极之间包括阴极,阳极和多个交替的阴离子可渗透膜和阳离子可渗透膜,其限定相邻膜对之间的浓缩和稀释流动通道。 稀释通道包括阳离子交换材料和阴离子交换材料,其相对于彼此紧密接触地固定,并为邻近的膜提供用于阳离子和阴离子的导电路径,并为材料之间的水提供流动通道。 阴离子交换材料和阳离子交换材料各自具有小于流动通道的特征尺寸的特征尺寸。 使用具有小尺寸的交换材料和阳离子和阴离子交换材料的固定紧密接触提供了增加的均匀的水分解和树脂再生,以及从流过稀释通道隔室的水中离子去除的高速率。 可以在稀释通道中提供增加的速度,通过将一部分水从稀释通道出口再次引入稀释通道入口或使用稀释通道中的流动分流器来为流动的水提供曲折的路径。

    • A process for and a system of removing volatile vapor solvents, particularly from paint-spray booths and paint dryers, and recovering such solvents, which process comprises: intimately contacting the solvent-laden air with a multiphase scrubbing media, particularly a water stream containing an oil-in-water emulsion or a surfactant or a powdered activated carbon, to capture and to dissolve the solvent vapor in the dispersed phase of the scrubbing media in a gas scrubber; removing the solvent-enriched scrubbing media and concentrating the solvent-enriched scrubbing media employing an ultrafiltration device; stripping the solvent from the concentrated solvent-enriched scrubbing media from the ultrafiltration device to remove and recover the solvent, while recycling the scrubbing media for further contact with fresh solvent-laden air; and recycling the water carrier as a permeate for reuse in contacting the solvent-laden air.
