Abstract Like all contaminants in potable water, the procedures used to remove manganese should aim at a fixed value in the finished water, preferably less than 10 μg L -1. It has been surprising to us that so much of the R&D work reviewed for this chapter dealt with percentage removal, and we point out that on the above absolute figure, 95% removal from water with more than 110 μg L -1 of manganese will not meet the criterion. Dam destratification or various oxygenation techniques will convert soluble manganese into insoluble forms, although it may not reduce the overall total manganese entering the treatment plant. Changes in other parameters, e.g. algal growth and variety, associated with in-dam processes should be considered before proceeding down this line of approach. Procedures for in-plant manganese removal will be virtually essential if manganese is present in the dam water, even if dam manipulation is used. The best and probably most economical approaches for successful removal appear to lie in adding oxidant to the water entering the filtration beds. However, there may be sound reasons for adding oxidant earlier in the process. Obviously, where any form of membrane filtration is used, the addition of oxidant may be unnecessary and even counter-productive.
