Jar test studies revealed that treatment with potassium permanganate at pH 7.7–8.0 was effective in the removal of iron, manganese and organics, which were responsible for causing colour and odour to water. Batch jar tests were carried out under a constant pH of 8.0, where the effect of parameters such as the oxidant dose, presence of co-ions (Ca 2+, Mg 2+) and alum addition on the removal of Mn 2+ and Fe 2+ was examined. Filter-Mate Potassium Permanganate blend is a powerful oxidant that is also effective for use when filtering manganese or hydrogen sulfide. Fact Sheet 6, Cornell Cooperative Extension.

In addition, these units require regular backwashing to remove the oxidized iron and manganese particles. potassium permanganate to provide an active supply of the higher oxides of manganese on the grains of sand, has been used fairly effectively for many years as a filter medium to oxidize and remove iron and manganese from water. endstream

It can also be used to control iron bacteria growth in wells. %%EOF
Natural sources of iron and manganese are more common in deeper wells where the water has been in contact with rock for a longer time. It is important to check the manufacturer’s maximum iron removal level recommendations, which typically range from 1 to 5 mg/L, before purchasing a unit. Indeed, oxidation by oxygen is in many cases not sufficient for manganese at neutral pH. this page may help. Permanganate is used in the iron (Fe) and manganese (Mn) removal processes in both surface water and ground water systems that employ filtration. Manganese dioxide coating on the filter media acts as a catalyst for the oxidation and reduction of iron and manganese. The CR method continuously feeds an oxidizer, such as chlorine, potassium, permanganate, or a combination of the two, into the raw water prior to the filter.

In coal mining regions of the state, these metals may also occur from both deep and surface mining activities. Potassium permanganate (KMnO4) is a very efficient oxidant of both iron and manganese. This means that dissolved Mn is found in the storage tank, oxidizes with the chlorine and causes turbidity. Manganese and iron ions are widely existing in surface and underground waters.
