Iron removal at groundwater pumping station Harderbroek

Iron is the primary source for discolouration problems in the drinking water
distribution system. The removal of iron from groundwater is a common
treatment step in the production of drinking water. Even when clear water
meets the drinking water standards, the water quality in the distribution
system can deteriorate due to settling of iron (hydroxide) particles or posttreatment
flocculation of dissolved iron. Therefore it is important to remove
dissolved and particulate iron to very low levels.
