Dharani Export-import Services (p) Ltd.

Vvd Road, Thoothukudi, Tamil Nadu

Dharani export import services (p) ltd is a major supplier of activated carbon from india. We supply material for domestic and international market we provide carbon solutions for mainly drinking water solutions. activated carbons are produced by natural steam activation of virgin coconut shell charcoal and subjected to acid wash . Resulting on unique patterned pores , offers excellent adsorption with reduced ash content and controlled ph level our gradesac 8x30ac 12x30ac 12x40 abrasionhardness number: relative measure of the ability of granular or pelletized activated carbon to resist at trition during handling and use. Absorption:: a process in which molecules are taken up by a liquid or solid and distributed throughout the body of the liquid or solid. Activated carbons do not absorb other materials (impurities). Activated carbon: a family of carbonaceous materials manufactured by processes that develop an internal pore structure with adsorptive properties. Iodine number: mgl, the amount of iodine adsorbed by one gram of carbon at equilibrium with a 0.02n iodine concentration filtrate. Mesopore: in activated carbon, a pore having a diameter between 20-500 angstroms. Macropore: in activated carbon, a pore having a diameter greater than 500 angstroms. Micropore: in activated carbon, a pore having a diameter less than 20 angstroms. Reactivation: the act of restoring adsorptive character to a contaminated activated carbon by a process similar to the original activation process. Surface area (b.e.t.): the total surface area of a solid calculated by the b.e.t. (brunauer, emmett, teller) equation, from nitrogen adsorption or desorption data obtained under specified conditions; square meters per gram.
