An experimental study of ozonation followed by slow sand filtration for the removal of humic colour from water

摘要

This paper describes a pilot plant study undertaken in Northern Itreland between November 1979 and October 1982 into the use of ozonation followed by slow sand filtration for the removal of humic colour from an upland water. Eleven sparate test runs were undertaken using a number of process combinations and a range of ozone dosages.
