Factors Affecting The Efficiency Of Activated Carbon

Granular activated carbon (GAC) is commonly utilized in for the removal of natural constituents and pool filter sand quantity residual disinfectants in water provides to improves the style and minimizing well being hazards;It protects other water remedy elements resembling RO membranes and ion exchange resins from possible organic fouling and damages . Due to its multi useful nature . Activated carbon is a favored water treatment method and the truth that it adds nothing detrimental to the treated water.

Most activated carbons are made from raw supplies equivalent to nutshells, coal , wood and petroleum.
The two primary 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 performance of activated carbon are:

pH:The organic removal exercise decreases with the rise in pH. Most organics compounds are less soluble and more readily adsorbed at a lower pH. . A thumb rule is to extend the carbon bed size by 20 p.c for each pH unit above neutral .
Molecular weight:The adsorbing property of activated carbon will increase with the rise in its molecular weight .. However, the pores sizes on the surface of the carbon must be massive enough to allow the molecules to move within. A mix of low and high molecular weight molecules should be designed and used species troublesome to removed..
Contaminant focus:
Higher the contaminant concentration, the better is the removal capacity of activated carbon. The contaminant is more likely to be adsorbed. As concentrations enhance, however, so do effluent leakages. The higher restrict for contaminants is just 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 in the water, so each time attainable, it's good to put activated carbon units upstream of the ion removal models
Particle dimension:
Activated carbon commonly available sizes are in 20 /50 mesh ,12 / forty mesh and eight / 30 mesh . The finer mesh provides one of the best contact and better removal.
Temperature:
viscosity decreases with the rise in temperature , thereby increasing adsorption rate.
Movement rate:
Usually, the decrease the flow rate, the more time the contaminant will get diffuse into the pore and be adsorbed.
