Techniques used in water treatment (waste and drinking) In Ouargla region

Abstract

Our study aims to evaluate the efficiency of techniques used in drinking water and wastewater treatment. Drinking water treatment relies on reverse osmosis technology to provide clean and safe water, free from contaminants and harmful microbes, meeting national standards. Wastewater treatment focuses on primary, secondary, and tertiary treatment to remove pollutants, prevent disease spread, and minimize negative environmental impact. It also emphasizes reusing treated water for irrigation. Results indicate that treated drinking water quantity is imbalanced with the capacity of the treatment plant. To address this, we recommend increasing water pumping or drilling additional wells to match untreated water levels with the plant's capacity, thus benefiting a larger proportion of the population. On the other hand, while treated wastewater is currently used for irrigation, our findings suggest that the quantity exceeds actual irrigation demands. This highlights the need to explore technical solutions to enhance treatment quality, allowing for a broader range of reuse applications. In conclusion, our study underscores the importance of assessing treatment technique efficiency. By addressing the imbalance between untreated water levels and treatment plant capacity, we can increase access to clean drinking water for more individuals. Improving treatment quality for wastewater opens up opportunities for expanded reuse, promoting sustainability a nd optimal utilization of our water resources
