Abstract :
In this paper, the oil-produced water (PW) mixed with fresh water (FW) was treated before it was injected into reservoirs. The effects of the factors such as pH value, variety and quantity of oxidants and inorganic flocculants, quantity and molecular of organic flocculants, the order and time of the reagents to be added on the water quality including amount of scale buildup, iron content, oil content, transparency, turbidity, were studied. After being treated, the fresh-waste mixed water reached the quality criteria of the injected water.
