الملخص الإنجليزي

Electrocoagulation Treatment can be considered as a favorable tool for the removal of many pollutants of various forms of wastewater.

These pollutants may include the removal of colloidal, the breaking-up of emulsions and heavy metals.

This process consists of the disintegration of the anodes (usually iron or aluminum), exciting the creation of coagulant mixtures in wastewater.

That will aid to coagulate contaminants and generate bubbles in favor of mixing and elimination of solids suspension by flotation.

Recently, the arrangement of using this technique with other treatment tools has turned out to be an interesting subject leading to an improvement in the removal efficiency of the treatment.

In this study, a combined treatment of electrocoagulation and ultrasound has been applied to treat three most common wastewaters in oil industry.

The ultrasound-electrocoagulation removal efficiencies for the removal of oil, suspended bentonite and zinc have been evaluated here.

In this work, a synthetic wastewater would be treated using electrocoagulation technique to reduce turbidity caused by pollutants.

This process has been done in a batch reactor equipped with aluminum/iron electrodes with and without agitation.

The effects of one of the most important parameter, i.e.

applied voltage on turbidity have been studied.

In addition, the effect of using ultrasonic has been also evaluated.

It was found when ultrasonic used with electrocoagulation, the turbidity increased for suspended bentonite and oily wastewaters and an improvement in removal efficiency for the heavy metals pollutants.

The results were compared and discussed
