Iron and manganese are common in ground water supplies. Excess iron and/or manganese levels usually results in the following:
Whilst the water supplied by the ground water source is often clear and colourless, it usually becomes discoloured once it comes into contact with air, causing iron and manganese to precipitate as rust.
There are a number of ways of removing iron and manganese from water supplies. The key to the removal process is oxidation of the iron and manganese ions, effectively converting them to rust particles and allowing them to be filtered out using a filtration process.
CWC uses an efficient and economical method of removing dissolved iron and manganese compounds from raw water supplies, by combining a manganese greensand and multimedia sand filter with a chemical-free oxidation column. This allows us to treat large volumes of water far quicker than any competitive iron removal system, making our equipment both smaller and more cost-effective. There are also no chemicals required for the operation of a CWC iron removal filter system, further reducing costs and making the system suited for use in remote areas.
Larger models also have the ability to provide disinfection of the treated water with a limited residual effect.
|Model||Flow Rates||Inlet/Outlet Ports|
|Service Flow Rates||Backwash|
|Minimum flow (m³/hr)||Maximum flow (m³/hr)||Flow (m³/hr)|
Operating pressure: 200-600 kPa
Power supply (automatic units): 220 VAC 50Hz
Temperature range (water temp): 5-35°C
Iron removal filters are capable of 10-micron effluent water quality under normal operating conditions. Designs are based on a maximum feed water iron concentration of 2 ppm, and a manganese concentration of less than 0.5ppm.
Note: In certain situations where iron and/or manganese concentrations are higher than those specified above, CWC iron removal filters can be used in conjunction with ozone, chlorine or aeration equipment.
In order to accurately size an iron removal filter for your residential, commercial or industrial application, we will need to know the following:
Your local approved CWC distributor can help you calculate your filtered water needs, and can arrange for a professional water analysis to be taken. For more information about iron removal filters and how the CWC filtration process can help you in your home or business, contact CWC today.
