IRON REMOVAL MEDIA
Oxidation involves the introduction of an oxidizing agent which chemically reacts with the iron or manganese to form an insoluble particle which can then be physically filtered out through a media bed.
Oxidation can be carried out one of the following methods:
- aeration - blowing/spraying air through the water
- addition of dissolved chemical oxidants - chlorine, chlorine dioxide and potassium permanganate (KMnO4)
- adsorption - greensand media and activated carbon
The process of oxidation followed by filtration is fairly easy and is often the treatment of choice. The use of ion exchange resins for the removal of iron and manganese has limited application due to the requirement that the contaminants be in dissolved form and at very low levels. This is due to the tendency of oxygen to react with the iron and managanes and therefore, increase the potential for plugging and buildup on the resin surface. Iron fouling is a common, and sometimes, irreversible problem with ion exchange treatment.
Treatment technologies for Iron and Manganese Removal from Groundwater:
MZ10 Plus Iron Removal Media
Acuro Organics Limited in association with Purolite, a premier manufacturer of resins from USA, offers MZ10 Plus Iron Removal Media. The dark-to-black colored catalytic media can remove soluble iron, manganese, hydrogen sulfide, arsenic and radium from water supplies. For drinking water applications the media can be effective for over 10 years.
- Advantages over the existing iron removal media - Can take max iron concentrations up to 20 ppm- Can reduce iron, Mn and H2 S up to < 0.1 ppm- No limitation of dissolved oxygen- No limitation of alkalinity and TDS in water- Needs only periodic backwash with treated water- Can be operated at high temperatures and high differential
pressures without breakdown of media No pre-treatment
required to remove chlorine in feed water- Used with chlorine, the media offers excellent resistance to
biological contamination- NSF approved

The greens and from our line-up comes to be a product of an excellent industrial and commercial utility. Our output comes to be fully capable of curtailing iron, manganese, and hydrogen sulfide from water through procedures of oxidation and filtration. We ensure that soluble iron and manganese comes oxidized and removed through a real contact with various other higher oxides of manganese on the greens and.
Manganese Green Sand
Manganese Greensand is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration.About Manganese Greensand Iron Reduction Media FiltersManganese Greensand is formulated from a glauconite greensand which is capable of reducing iron, manganese and hydrogen sulfide from water through oxidation and filtration. When the oxidizing capacity power of the Manganese Greensand bed is exhausted, the bed has to be regenerated with a weak potassium permanganate (KMnO4) solution.
Advantages of Manganese Greensand Filters- Iron reduction over wide pH range- Effective reduction of hydrogen sulfide in addition to iron
and/or manganese- No harmful effects from a chlorine feed- Low attrition for long bed life

|Model/Type||Green Sand - Manganite|
Manganite (greensand) is a black filter medium used for removing soluble iron, manganese and hydrogen sulphide from well water supplies. It also has the capability of removing radium and arsenic. It is processed from the mineral zeolite ( a light weight granular core) with a manganese dioxide coating is deposited on the surface of the mineral grains. Each grain has a finite amount of manganese dioxide coating it. Unlike in-situated media, there is no need for any extensive pre-conditioning of the filter media to try to apply a coating. The filter media is ready to install in the filter and be regenerated.
The manganese dioxide coating acts as a catalyst in the oxidation reduction reaction of iron and manganese. The media can be used in two methods of operation: continuous regeneration (cr) and intermittent regeneration (ir). The cr method is recommended for predominantly iron bearing waters with or without the presence of manganese, and the ir method is recommended for use on ground waters in which manganese predominates. Additionally, manganese greensand is listed under ansi/nsf standard 61 for portable water treatment components.

Iron Removal Filters
Minimum Order Quantity: 500 Kilogram
We are amongst the reputed manufacturers of iron removal filters, used for removal of dissolved iron, present in the form of lower oxides. Designed in line with international quality standards, these filters are used for removing both oxidized iron and iron present in solution. Compact size plants have filter media that are capable of removing small amounts of hydrogen sulfide.
With practical upper limit of iron concentration for these filters being 5 ppm, the filter has three functions:
It acts as an efficient filter in removing oxidized iron and sediment
It acts as a compact catalyst in augmenting the union of oxygen and dissolved iron in water to form oxidized (filterable) iron (the water must contain at least 0.1 ppm oxygen for every 0.7 ppm of iron)
In case where the water has little or no oxygen the media will give up some of its own store of oxygen to oxidize iron
In order to restore the media, it must be periodically regenerated with potassium permanganate (depending upon oxygen content of water). To facilitate regeneration, optional regenerant systems are available. For efficient application, the pH must be at least 6.8 and temperature should not exceed 120° F. To aid in the oxidation of iron, the chlorine or potassium permanganate may be fed into the water ahead of the iron filter.
