Treatment of the oily produced water (OPW) before injection into oil reservoirs is necessary to reduce formation damage. This can be done using chemo-physical process minimize droplets in water. In this respect, work aims extract natural polymer (chitosan) from shrimp shells and mix it with coagulants (chitosan/carboxy methyl cellulose chitosan/aluminum sulfate) adsorb OPW. Adsorption experiments were carried out batch mode firstly choose best treatment, also investigate effects pH on adsorption uptake, adsorbent dosage, coagulant mixture doses contact time. It was found that removal by chitosan reached 96.35% 59% at = 4 9, respectively. The ability remove increased after adding different CMC/or aluminum sulfate average mixing time between 30 60 min. highest efficiency chitosan/CMC 99% (90% chitosan: 10% CMC) chitosan/Al2(SO4)3 85% (80% 20% Al2(SO4)3). SEM photographs chitosan, as showed lies alone mixture. Generally characterized significantly its high petroleum suspended solids OPW, additionally, reduces economic cost treatment.
