Document Summary

Tianyu hou, 26995194 feb. 22, 9:00 10:50. Within several methods of coagulation, adsorption of activated carbon is one of the most efficient and well-known way to the water and wastewater treatment process. Adsorption is the process when ions and molecules which are presented in one phase tends to concentrate or condense into another phase, which is also highly-efficient on eliminating colors, pharmaceuticals, endocrine disruptors and organic contaminants during the water treatment. The most common chemical for adsorption is activated carbon which then can be divided into powdered activated carbon (pac) and granular activated carbon (gac). The reason why activated carbon is widely used in the field is due to its high surface area in relation to its mass. According to past experiment, nearly 80% - 90% of the organic contaminants within water can be segregated by using fresh activated carbon. Ceq: the solute concentration at equilibrium in g/m3 qeq: the adsorbed concentration at equilibrium in gsolute/gadsorbent.
