The WTI-300 iron and manganese removal filters contain a mixture of quartzite and pyrolusite, a specific manganese oxide that acts as a catalyst for the oxidation of iron and manganese, leveraging the action of an oxidizing agent added to the water (sodium hypochlorite). The catalytic process takes place on the surface of the granule, leading to the formation of a floc that is mechanically retained by the quartzite in the filter bed itself. During operation, there will be a gradual clogging of the filter bed, resulting in an increase in pressure losses. It becomes necessary to periodically perform backwashing, an operation that sends water in countercurrent through the filter bed, removing accumulated solids and restoring the original filtration capacity.

The WTI-300 iron and manganese removal filters are specially designed and manufactured pressure rapid filters for reducing iron and manganese in well and groundwater. The WTI-300 filters are suitable for treating water intended for human consumption, technological use, or industrial processes.

The WTI-300 iron and manganese removal filters are available in STANDARD and LUNA models (both can be constructed with stainless steel or polypropylene pipes). The LUNA models have the advantage of a lower height for the same diameter, thanks to the integrated manhole with the pipe inlet. Each model and execution are available in manual (up to 1200 mm diameter) and automatic versions (with pneumatic valves).
