Filter Media Mineral Coatings: Filtration Theory and Practice 过滤介质矿物涂料:过滤理论与实践
发布日期: 1994-01-01
这项工作最初是为了从根本上表征涂有氧化锰矿床的过滤介质的成分、表面化学和微观形貌。地质科学技术用于确定矿物涂层表面的矿物学和催化性能,以用于锰去除的动力学模型。在存在游离氯的情况下,矿化过滤介质通过称为“天然绿土效应”的非生物吸附和氧化过程催化可溶性Mn2+的去除描述性研究试图将矿物表面络合理论应用于无机溶质剖面和突破行为的动态过程建模。除了描述性研究外,还开发了用合成氧化锰快速涂覆介质的方法。
This work began as an effort to fundamentally characterize the composition, surface chemistry and microtopography of filter media coated with manganese oxide mineral deposits. Techniques from the geological sciences were used to determine mineralogical and catalytic properties of mineral coating surfaces for use in a kinetic model of Mn removal. In the presence of free chlorine, mineralized filter media catalyze soluble Mn2+ removal by an abiotic sorption and oxidation process known as the "natural greensand effect." The descriptive studies were an attempt to apply mineral surface complexation theory to dynamic process modeling of inorganic solute profiles and breakthrough behavior. In addition to descriptive studies, methods were developed to rapidly coat media with synthetic Mn oxide.
