Water quality evaluation for selected places in the Daura refinery

الملخص EN

The present work deals on environmental evaluation of the water quality used in the Daura refinery.

An overall survey throughout the period of the study (Dec 2007–Sep 2008) resulted in the recognition of the potential sources of contamination from the refinery, loading and the maintenance operations.

A monitoring well was dug in the most polluted location to check for water quality.

A sampling plan was made to evaluation the various used water including process water, treated wastewater, rain water, drinking water and ground water.

The samples collection was accompanied with the use of Global site system, GPS for documentation process.

The samples were prepared for the determination of hydrocarbon groups and indicator compounds using extraction procedures.

During the evaluation of water quality, periodically samples were collected from the final effluent of the waste water treatment plant.

The results of the analysis indicate that the average wastewater quality is in agreement with the valid environmental imitations.
