Kinet ic survey and therm odynami c modeling of reduc tion COD sewer by adsorbents: in methanol unit of Fanavaran petrochemical company

Adsorption technology is curre ntly being u sed extensively for the removal of organic an d inorgani c micro pol utants from aqueous s olutions. Pe trochemical industries g enerate lar ge quantities of waste water, whic h are very toxic and difficult to be disposed by physica l, chemical and micro biological m ethods. Petrochemical wastewater is characterized by hig h chemical oxygen de mand (COD is resistant to conventio nal wastewater treatment). Activate d carbon h as been widely used in wastewater treatmen t to remove organic a nd inorganic pollutants. Possessing high surface area, activated carb on frequently exhibits high removal efficiency for most dissolved compound s. Activated carbon is expensiv e; therefore, develop ment of low cost altern ative adsorbent has b een the foc us of recent research. A number of workers h ave used different materials as the adsorbent for the removal of different pollutants [۱-۲].
