Iron Remove Plant

MEET provide Iron removal filter and Multimedia filter which remove Iron, Manganeze, Arsentic. During cross downflow of the water Fe++, Fe+++, Mn++, Mn+++, As(3) and As(V), will be oxidized to make flock. This flock will hold in between granular space of the media and those water will be free from Iron, Manganeze, and Arsentic. MEET also provide Activated Carbon Filter to remove color, residual chloride, odor and adjust pH value. Both coagulation separation and Reverse Osmosis is removed Arsenic.


Effect of Excess Iron in Drinking water

Water becomes brackish color, rusty sediment, bitter or metallic taste, brown-green stains water gets iron bacteria, discolored beverages Excess iron causes gastrointestinal distress certain types of bacteria thrive in water with iron content and give it a rotten egg smell.


Activated carbon is charcoal that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. The treated or activated carbon has a massive surface area (2000 - 3000 square metres per gram of activated carbon) making it highly effective at adsorbing tastes and odours, as well as chlorine and organic colour from water.

An activated carbon filter is a filter housing (either a cartridge filter housing or a granular activated carbon media filter is used for activated carbon filtration) containing granular activated carbon or an activated carbon block cartridge.


Low flow applications - activated carbon cartridge filters: water flows from the outside of the activated carbon cartridge to the inside of the activated carbon cartridge, through a collector tube, and out to process or the point-of-use. When the activated carbon becomes exhausted, or blocked with suspended matter, the cartridge has to be replaced.

High flow applications - At CWC we use our conventional multimedia sand filter design, replacing a portion of the multimedia filter repack with granular activated carbon. This allows the filter to act as both a sand filter and an activated carbon filter, removing suspended particles, taste and odour, chlorine and organic colour. When the activated carbon becomes blocked with suspended matter, the filter can be backwashed in the same way as a conventional sand filter. When the activated carbon in the filter becomes exhausted, it is usually replaced, although some of the systems we manufacture are fitted with steam sterilization components, to regenerate the activated carbon bed.

Multimedia Filter:

Multimedia filter also called as mechanical filter, is composed of deep-bed system with multi layers of media in the tank. The major media to be applied in the system of sand and anthracite. The lightest and coarsest material is located at the top layer of bed for the removal of the largest suspended particles, while the heaviest and finest one is located at the bottom layer of bed to remove smaller one present in the source water.

The sand usually acts as a form of chemical treatment that, when in contact with soluble iron in water, reduced the iron from the soluble form to an insoluble form that will precipitate out out of solution. The anthracite then can filter both the precipitated iron out of the solution as well as other entrained particles that have entered the water source. The combination of anthracite and sand together can remove a majority of suspended particles greater than 10 microns in size. After treatment, the SDI (Silt Density Index) is reduced and the turbidity reaches less than 3 from 20. The systems require backwashing to remove the accumulated contamination of suspended particles and rinsed by down flow clean filtered water before use in order to extend bed life.

Multimedia Filteration is widely used in the water pre-treatment, which available with Automatic and/or manual operational features. The tank material fiber glass reinforced plastic and stainless steel.
