Many times, due toincorrect selection, after intalling of the equipment, it turns out that the built-in iron remover technology is not suitable for manganese removal. This wrong technological definition can be very expensive, so we suggest if you have manganese on your water, we prefer slightly more expensive and perhaps ”combined” technology, but do not spend money unnecessarily on something that does not work properly in the end. Here too, as in the selection of the iron remover equipment, some practical factors such as there is operating staff, how much space is available, and how much money we spend on its instalation and the operation.
