Iron & Manganese Removal

Efficient iron and manganese removal treatments in the West Midlands

The process is dependent on the type and amount of iron and manganese found in a sample of water and the other mineral compositions. We provide bespoke solutions after testing your water source. For services across the West Midlands, London, Lancashire and Wales, contact our team today.

Iron and manganese removal

Iron and manganese are commonly found in our water supply. They can cause unsightly staining and they can cause health problems. Catalytic oxidation is a tried and tested method of oxidising both iron and manganese to form a precipitate and then holding on to it until it is automatically backwashed to drain.

If you require an iron and manganese removal system for your business, you can call D. A. Baldwin & Son in Wolverhampton on 01902 700 456. We also supply sediment filters, RO systems, water softeners, decal units and water coolers for commercial businesses.

Aquamandix

Aquamandix

Used for iron and manganese removal by catalytic oxidation. It is a robust natural mineral conforming to British Standard BS EN 13752. It requires a pH of 7 or more for iron removal and 8 for manganese removal. Aquamandix is a cost effective filter media which can be mixed with sand where the Aquamandix catalyses the metals and then the less expensive sand filters out the precipitate. It can also be mixed with pH media to and increase the pH all in one system.

Filox

Filox can be used for iron, manganese and hydrogen sulphide removal by catalytic oxidation. It is a robust media allowing a faster service flow rate than other iron removal media. A pH of 7 is recommended for iron removal and 8 for manganese removal. It is a heavy media requiring a strong backwash. Adding other media is possible but can impair its service flow rate.

 Birm

Birm

Birm is a relatively inexpensive material which can be used for iron and manganese removal by catalytic oxidation. It requires a pH of 7 or more for iron removal and pH 8 for manganese removal. It is advised not to use Birm in combination with chlorination and the water should be free of oil and hydrogen sulphide. If the pH of the water is too low pH correction may be required. Birm is a light, inexpensive media but often doesn’t last quite as long as other natural media.

Manganese Greensand/MTM

These media will remove iron, manganese and hydrogen sulphide which are all oxidised by the media. This oxidation capacity becomes exhausted and is periodically regenerated by potassium permanganate or chlorine. They operate over a wide pH range (6.2 to 8.8), sometimes without requiring pH correction.

sediment filters

How does it work?

Water flows into the valve at the top, down through the media and then up through the ‘riser’ tube in the middle of the vessel. As the water travels through the media the iron and manganese are oxidised bringing the metals out of solution and trapping them so only clean clear water flows out to service. These systems also act as sediment filters trapping any natural turbidity. As the media act as a catalyst, they do not need to be topped up or replaced on a regular basis. There are timer options that can be set to automatically self-clean (backwash) and wash away any of the accumulated iron and manganese. The Aquamandix, Filox and Birm filters require dissolved oxygen in the water to oxidise the metals. This normally is present naturally but can be added by aerator or as an air filtration option. Greensand and MTM contain a lower concentration of active catalyst so require frequent regenerations with oxidation chemicals like potassium permanganate.
D. A. Baldwin & Son supplies and installs iron and manganese removal systems for various commercial businesses in the West Midlands, London, Lancashire and Wales.
