The High Lock uses a special filtration agent with catalytical action that promotes oxidation.
As a result, when the water passes through the special filtration agent, the iron that is dissolved in the water is oxidized and eluted as insoluble steel. This is adsorbed by the special filtration agent, and the iron is removed. This filtration agent, which acts both as a catalyst and as an adsorber, is unique to the High Lock. Also, if there is manganese in the raw water, the iron is removed in the first tank, then chemicals are injected at the inlet in the second tank, the pH is raised, and the manganese is removed.
