Factors Affecting The Performance Of Activated Carbon
Granular activated carbon (GAC) is commonly utilized in for the removal of natural constituents and residual disinfectants in water provides to improves the taste and minimizing health hazards;It protects other water treatment parts comparable to RO membranes and ion exchange resins from potential natural fouling and damages . Due to its multi functional nature . Activated carbon is a favored water therapy approach and the truth that it adds nothing detrimental to the treated water.
Most activated carbons are made from raw supplies reminiscent of nutshells, coal , wood and petroleum.
The 2 basic principal by which activated carbon removes contaminants from water are adsorption and catalytic reduction. Organics wastes are removed by adsorption and residual disinfectants are removed by catalytic reduction.
Factors affecting the efficiency of activated carbon are:
pH:The organic removal activity decreases with the rise in pH. Most organics compounds are less soluble and more readily adsorbed at a decrease pH. . A thumb rule is to increase the carbon bed measurement by 20 p.c for each pH unit above neutral .
Molecular weight:The adsorbing property of activated carbon increases with the increase in its molecular weight .. Nonetheless, the pores sizes on the surface of the carbon have to be massive enough to permit the molecules to move within. A combination of low and high molecular weight molecules needs to be designed and used species troublesome to removed..
Contaminant focus:
Higher the contaminant focus, the better is the removal capability of activated carbon darco g-60 carbon. The contaminant is more more likely to be adsorbed. As concentrations enhance, however, so do effluent leakages. The higher limit for contaminants is a few hundred PPM . Higher contaminant concentration might require additional contact time with the activated carbon. Additionally, the organic removal is enhanced by the presence of hardness within the water, so at any time when potential, it's good to place activated carbon models upstream of the ion removal items
Particle measurement:
Activated carbon commonly available sizes are in 20 /50 mesh ,12 / forty mesh and eight / 30 mesh . The finer mesh offers the perfect contact and higher removal.
Temperature:
viscosity decreases with the rise in temperature , thereby increasing adsorption rate.
Circulate rate:
Typically, the decrease the movement rate, the more time the contaminant will get diffuse into the pore and be adsorbed.
