Globally, the drinking water industry is responding to new developments and increased regulations. Microbial removal, treatment of inorganic contaminants, disinfection byproduct control, and improved analytical methods that can detect potentially harmful contaminants at part-per-trillion levels add to increased demands on water treatment. This, without escalating costs.
Activated carbon water treatment technologies offer effective, cost-efficient, and environmentally benign solutions to address key potable and groundwater treatment requirements.
ACID WASHED ACTIVATED CARBONS
Active carbon contains large amount of acid soluble inorganic material depending on the precursor and its source of origin. Active carbon has very high capacity to adsorb organics, inorganics, bad taste and odour material. Adsorption capacity is enhance by modifications such as acid washing because this modification removes the acid soluble inorganic materials from the carbon and make it more porous, efficient and useful for various liquid process applications such as waste water treatment, water purification, decolourisation process in chemical and pharmaceutical industries, food and beverage industry for many purposes such as decolourization of sugar, dechlorination, decaffeination, purification of organic compounds,etc.
We manufacture acid washed active carbons as per the customer requirements for the applications mentioned above.
FEATURES & BENEFITS
Some of the benefits of Acid Wash carbon include Dechlorination of water, better taste, removal of bad odors, removal of color from water, removal of organic substances, etc. Acid wash carbon has extensive internal structure, neutral surface, maximum hardness, extended operational life, high volume activity, and rapid pH stabilization.
Acid wash carbon is used in various applications such as Condensate de-oiling, semiconductor process water, and protection of reverse osmosis membranes from chlorine and organic fouling.
Silver Impregnated AC / Bacteriostatic
One of the main applications of granular activated carbon is the purification of water. Its function is the retention of organic contaminants and the elimination, by chemical reaction, of the free residual chlorine that remains in the water after the disinfection stage. The removal of free chlorine takes place in the first few centimeters of the carbon bed, so there is no longer any protection against bacterial growth in the rest of the bed. Sooner or later, bacteria can enter from a poorly disinfected influent, or from some point in the effluent pipe. This may happen mainly when there is no water circulation while the equipment is out of service. Bacteria reproduce, and turn the carbon bed into a source of contamination.
In order to inhibit bacterial growth, the surface of the carbon is impregnated with 0.1% metallic silver to make carbon bacteriostatic using ionic silver to enable it to bind strongly with carbon surface to make it suitable to function and purify large volumes of water.
FEATURES & BENEFITS
● High efficiency
● Negligible silver leaching
● No health hazards to humans
● No loss in Bacteriostatic property up to 6000 litres water
● Available in Granular and block form
LIQUID PROCESS PURIFICATION
Due to their high adsorption capacities and other functionalities including chemical reduction, catalysis, and carrier of biomass and chemical, activated carbons are widely used in many industrial separations.
Activated carbons prove effective in the chemical, refinery, food, and pharmaceutical industries to treat raw ingredients and finished products, especially in the removal of organic contaminants.
In general, the adsorption capacity of activated carbon is proportional to the internal surface area, pore volume, pore size distribution and especially the surface chemistry. There are numerous reports of more organic adsorption in pores that are barely large enough to admit the adsorbate molecule; for example, it has been pointed out that dyes and humic acids have dimensions (1.5–3.0 nm) that favour their adsorption in mesopores. Hence, the difference in pore size distribution affects the adsorption capacity for molecules of different sizes and shapes. The removal efficiency can be further enhanced by the electric force between the carbon surface and the adsorbate.
In some cases, adsorption depends upon dissociation of particular functional groups—which in turn depend on the activation condition, activating chemical and the conditions of application. Activated carbon therefore is required to be customized as per the specification of the user depending on the application. We carry out physical and chemical modification with and without impregnants of activated carbons to customize them and the best examples are our military grade carbon, CO adsorbent based on active carbon, heavy metal removal carbon, iron removal carbon, etc.
