Performance and Optimization of Hybrid Membrane-Adsorption Systems: A Case Study for the Racine Water Utility
混合膜吸附系统的性能和优化:Racine Water公用事业公司的案例研究
本文回顾了为威斯康星州拉辛市进行的一项初步研究的结果,该研究调查了使用粉末活性炭和浸没式超滤膜(PAC-UF)的混合膜吸附工艺的性能,以解决两个主要的处理目标:升级消毒;以及去除味道和气味(T&O)。特别是,该研究侧重于2-甲基异龙脑(2-MIB)的去除,2-MIB是拉辛和许多其他水厂常见的T&O化合物。中试研究考察了反洗频率、PAC投加量、PAC投加方法(连续投加与脉冲投加)和给水预处理的影响,以更好地优化吸附过程,并证明膜单元在各种PAC-UF操作条件下的性能。试点信息用于确定适当的设计标准,并随后提供添加PAC的预算成本估算-
UF工艺用于拉辛每天6000万加仑的水厂。估计资本成本为3300万美元。PAC-UF系统的预计年运营成本为110万美元。包括9个参考文献、表格和图表。
This paper reviews the results of a pilot study conducted for theCity of Racine, Wisconsin that investigated the performance of a hybrid membrane-adsorption process using powdered activated carbon and submerged-style ultrafiltration membranes (PAC-UF) to address two major treatment goals: upgraded disinfection; and, taste and odor (T&O) removal. In particular, the study focuses on the removal of 2-methylisoborneol (2-MIB), which is a common T&O causing compound for Racine and many other water utilities. The pilot study investigated the effects of backwash frequency, PAC dose, PAC dosing method (continuous vs. pulse), and feedwater pretreatment in an attempt to better optimize the adsorption process and demonstrate the performance of the membrane unit with various PAC-UF operating conditions. The pilot information was used to determine appropriate design criteria and subsequently provide a budgetary cost estimate for adding a PAC-UF process to the 60 million gallons per day water plant in Racine. The estimated capital cost is $33 million. The estimated annual operating cost of the PAC-UF system is$1.1 million. Includes 9 references, tables, figure.
