颗粒活性炭的使用可能会增加，以符合1986年《安全饮用水法》修正案的规定。味觉和气味系统中的碳寿命很长，因此很少使用高效的碳去除和再生系统。然而，用于去除VOC、SOC、消毒副产品和有机前体的GAC系统的设计比用于去除味道和气味的GAC系统更复杂。这并不是说过滤器/吸附器将不再使用，而是它们的效用将降低，设计程序将改变。然而，许多水处理厂可能需要安装深床GAC柱，以实现拟议和预期法规规定的处理目标。此外，还必须设计和安装高效的运输、储存和再生系统，以使这些系统运行正常。 因此，本演示将讨论为确保高效吸附过程而必须解决的一般工艺设计考虑、详细设计考虑和操作考虑。

The use of granular activated carbon is likely to increase to comply with the provisions of the 1986 Amendments to the Safe Drinking Water Act. The carbon life in taste and odor systems is so long that efficient carbon removal and regeneration systems are seldom used. However, the design of GAC systems for the removal of VOCs, SOCs, disinfection byproducts, and organic precursors is more complex than those for taste and odor removal. This is not to say that filter/adsorbers will no longer be used, but their utility will be reduced and the design procedures altered. However, many water treatment plants may be required to install deep bed GAC columns to achieve the treatment objectives mandated by the proposed and anticipated regulations. In addition, efficient transport, storage, and regeneration systems will also have to be designed and installed in order to make these systems operationally functional. This presentation will therefore discuss the general process design considerations, detail design considerations, and operational considerations that must be resolved to ensure an efficient adsorption process.
