Iron removal and manganese removal plants - plant engineering
Groundwater or well water that is to be used as drinking or process water can absorb different amounts of iron and manganese, among other things, on its way through the different layers of the earth, through clay, sand and limestone. In order to be able to use this water safely as drinking water or process water, it should be freed from these elements. Iron and manganese can form deposits in process water circuits, which reduce pipe cross-sections and increase pressure losses in the pipes. Systems through which water containing iron and manganese flows are also damaged over time by these deposits.
For drinking water use, a limit of 0.2 mg/l for iron and a limit of 0.05 mg/l for manganese must be observed.
In principle, two types of filter materials that have been tried and tested over many years are suitable for iron and manganese removal. Iron and manganese can often be removed from the process water using simple and robust Birm filters. Birm is a filter material coated with manganese dioxide, on the surface of which dissolved iron and manganese are oxidized. Iron and manganese oxides can be filtered out as particles. Birm filters do not require any chemicals for regeneration. Backwashing to wash out the particles is sufficient.
An alternative to Birm is the Greensand Plus filter material. This filter material is also coated with manganese dioxide. It offers the advantage that hydrogen sulphide, arsenic and radium can be removed from the raw water at the same time. In addition, Greensand Plus is considered to be more durable at higher temperatures and pressures.
GB Chembridge International has many years of experience in using both filter materials. For a correct selection and design of the process, an analysis of the raw water by our laboratory is required. This is the only way we can give you the best possible advice. If necessary, the use of a so-called open iron removal system can also be advisable. For smaller volume flows of up to 4m³/h, filter systems are suitable, which as standard consist of a robust GRP pressure tank and a control valve, which is required for automatic backwashing. Systems with Greensand Plus also have a container for potassium permanganate to regenerate the filter medium.
We advise you individually to find the best procedure for your needs.
