In this study,the treatability results of olive mill wastewater (OMW) using acid cracking,coagulation,Fenton oxidation and adsorption processes are presented.Various coagulants,such as alum and ferric chloride were used in coagulation experiments.The effect of coagulants,iron-salt,and hydrogen peroxide dosages,and activated carbon concentration on treatment efficiency was evaluated,and optimal conditions were established.Acid cracking and coagulation showed high efficiency of chemical oxygen demand (COD) (73%),phenol (84%),and suspended solid (SS) (90%) removal from the OMW.As a result of this study,the COD reduction increased to 95% though when acid cracking and coagulation were coupled with Fenton.
