氧化后去除悬浮固体的过程可以有效地去除水中的可溶性铁和锰。去除铁和锰的三种常见工艺是曝气过滤、氯化过滤和高锰酸钾绿砂过滤。本文描述了这些过程，并介绍了氯化过滤的初步研究结果。氯化过滤中氧化剂的成本低于高锰酸钾-锰绿砂过滤。包括12个参考文献、表格和图表。

Processes in which oxidation is followed by removal of suspended solids can effectively remove soluble iron and manganese from water. Three common processes for removing iron and manganese are aerationfiltration, chlorination- filtration, and potassium permanganatemanganese greensand filtration. This article describes these processes and presents results from a pilot study of chlorination- filtration. The costs for oxidants in chlorination- filtration are less than those for potassium permanganate- manganese greensand filtration. Includes 12 references, tables, figures.
