Heavy Metals Removal Blocks (HM)

Their toxicity may occur due to industrial emission that contaminates waterways, nearby streams and rivers, contamination of irrigation water, the application of fertilizer and metal-based pesticides, harvesting process, transportation, storage, or sale. This contamination is a widespread environmental problem. The harmful effects caused by heavy metals in water to living organism if excess amount is ingested through food. Elements, such as Cadmium and Chromium, are considered carcinogenic, while Iron, Copper, Manganese, Zinc, and Nickel are considered essential trace elements). Painting paper, pigment, fuels, photographic materials electroplating, battery manufactures, explosive manufacturing, and metal working industries discharge a large amount of heavy metals, including Copper, Zinc, Lead, and Nickel ions in water bodies which cause serious environmental contamination.

Arsenic is also another heavy metal which is available in almost 70% bore well water. Therefore, it is essential to purify the water to make it potable. The conventional methods for heavy metal removal from waste water which includes chemical precipitation, reverse osmosis, and solvent extraction are expensive especially for developing countries. Adsorption on adsorbent such as active carbon or modified active carbon is an alternative method, because it is cost effective and simple to design.

Activated carbon is a term for a family of highly carbonaceous materials none of which can be characterized by a structural formula. It is an amorphous solid consisting of micro crystallites with a graphite lattice, and they are non polar, highly porous, usually prepared in small pellets or a powder. The limitation is that it reacts with oxygen at moderate temperatures (over 300 °C). It is obtained from carbonaceous material; carbonization and activation are the two phases of manufacturing activated carbon. Waste water is any water that has been adversely affected in quality by anthropogenic influence and can originate from a combination of domestic, industrial, commercial, or agricultural activities, surface runoff, or storm water, and from sewer inflow or infiltration. We manufacture not only active carbon suitable for liquid processing to treat the waste water to sewage water but also we modified the carbon and made it a high oxidant to remove heavy metals such as Pb, Hg, As, Cr and Cd by impregnating with active MnO2. Based on MnO2 impregnated carbon we developed and manufactured HMR Carbon block. Presently, removal efficiency of HMR blocks is 70-80%.

• Manufactured from Coconut Shell based modified, micro porous MnO2 Activated Carbon
• Designed to be used in most standard size housings.
• High HMR removal capacity
• Simultaneously removes chlorine, bad taste, odour and organic contaminants from water
• Provides particulate filtration and high dirt holding capacity.
