Iron & Manganese Removal Plant
Location: Sheffield, Yorkshire, UK
Capacity: 20 m³/hour
Designed to remove Iron and Manganese prior to base- exchange softening from a borehole water supply.
Most boreholes in the UK have a high level of soluble iron present and as such if it is not removed will cause staining, product impairment and if used for drinking water will be non- compliant with the EU drinking water directive.
In this application the water would have also fouled the base-exchange softening resin.
The water was contaminated with approx 2.5 – 3.0 ppm of iron and manganese with a hardness of 450 mg/lt.
The treatment plant when installed consisted of a purpose built aeration tower with sump, hypochlorite dosing, iron & manganese removal filtration and base exchange softening.
The treated water is used for preparation of ‘Ronseal Garden Products’.
The unit continually produced water less than 0.1 ppm iron, with a constant hardness of 45-50 ppm.
