Abstract: The objective of this research project is the examination of the major factors governing the efficiency of removal or iron and manganese from water supplies. This objective has been met through a multi-faceted study involving the following major components: review of problems created by iron and manganese in Australian water supplies with particular reference to selected water sources; review of methods used for removal of iron and manganese from water supplies; and detailed laboratory studies of the critical processes of Fe(II) and Ma(II) oxidation, iron and manganese oxide aggregation (coagulation/flocculation) and particle removal by filtration. The process studies indicated above have been undertaken under both simple, idealised conditions (i.e. using well characterised particulate oxides and relatively simple solution conditions) and under conditions more typical of a water treatment plant. The latter studies have been undertaken for the most part using the waters of Mardi Dam in the New South Wales shire of Wyong. In this report, the reviews of problems caused by iron and manganese and the methods available for the removal of these elements from water supplies are documented in the main body of the report. Particularly extensive studies have been undertaken of the aggregation of colloidal oxides and methods used and results of studies undertaken under relatively simple, well defined conditions are given in Appendix 1.
