Is the deferrization rate (i.e. iron separation) optimal?
Plant: MOFI 4x10C – mobile 4x gravel filter plant for deferrization in a container
He continues, ‘The advantage of a magnetic drum separator is that the deferrization can take place in a continuous process.
55 m³/h of gross water is converted into drinking water by means of deferrization, manganese removal, disinfection with ClO2 and nanofiltration.
The deferrization efficiency of overbelt magnets varies from 70 to 90%; this depends on magnet design, product flow and placement.
simple iron removal without sedimentation (aeration-filtration)
A pressurised biological iron removal unit will include (figure 29):
Examples of physical-chemical iron removal systems including open aeration
Physical-chemical iron removal: typical example of a pressurised unit producing 600 m3 · j–1
Partial carbonate removal at a pH in the region of 8 can, therefore, result in total iron removal.
The core active components, termed as de-ironizing inducers (Dll), consist of a reducing agent and a precipitating agent.
The feeding opening (106) is used for feeding the pulverized coal ash to be de-ironed, and the tailing bucket (107) is used for discharging the non-magnetic particle after de-ironing.
By adopting the vertical ring magnetic separator and the method for magnetically separating and de-ironing of pulverized coal ash, the de-ironing effect is improved by 20%.
Removal of iron (Fe) and manganese (Mn) from water
Removal of iron (Fe) and manganese (Mn) from water
Lubron has a wide range of standard units for iron and manganese removal, with a maximum hourly operating capacity of 80 m3/hour.
In some cases, additional maintenance such as caulking or weather stripping may be necessary.
The Orezza factory has set up a process to remove the iron, using a totally natural process: air oxidisation.

If softening is not required and the pH value is sufficiently high, classic deferrisation can be used.

The magnet filter can be used in tubes or piping in the food sector and serves to remove iron particles from products that are transported under pressure.
Furthermore, unlike what happens during physical-chemical iron removal, crystalline type oxihydroxides, especially lepidocrocite (γ-FeOOH).
Partial carbonate removal at a pH in the region of 8 can, therefore, result in total iron removal.
To take red water iron out of water, or over the maximum of clear water iron, an iron filter or other equipment is needed.
Iron removal plants can be based on different filtration media, depending on the iron and manganese concentration, the oxygen level, CO2 content and hardness of the water.
Recycling of supernatant or filtrate from "red water" waste treatment facilities to the head end of an iron removal plant shall not be allowed except as approved by the reviewing authority.
It is not consumed in the iron removal process and therefore provides a positive economic advantage over many other iron removal medias.
When H2S is present, it has to be removed either through aeration at the inlet (gravity iron removal), or biologically (pressurised treatment) (see section h2s removal).
