Statistical analysis of the physico-chemical characteristics of industrial effluents: Case of evaporating basins used as final storage for effluent

Abstract

Evaporating basins are common storage for industrial effluent in most renewable power plants. Various types of research on the environmental consequences and issues of this experience have suggested this method of disposal to prevent industrial effluents withdrawal into the ocean, and dams and prevent water contamination.Nevertheless, this approach may have significant worldwide environmental implications. Focusing on dedicated research methods for a power plant in the south of Morocco that employed evaporating basins for storing its effluent, we evaluated the development of the effluent's Physico-chemical characteristics over a timeframe of one year.The evaporation basins undergo thorough assessment to evaluate the effects of industrial effluents, leading to the observation of a significant increase in the physicochemical characteristics of the discharged effluents, mainly EC, BOD5, Na, and Cl2. This rise in water contamination can be attributed to the aforementioned factors. Statistical analysis, specifically correlation and regression, was employed to examine the coefficients of the primary physicochemical properties. The objective was to determine the effluent characteristics that exhibited strong associations and close relationships.The primary goal of this study is to highlight the drawbacks associated with storing wastewater in evaporation ponds, a common practice among many industrial companies. It is crucial to consider that these ponds attract a diverse range of bird and animal species, and any contamination of the water can pose significant environmental and ecological risks in the event of an accidental leakage or spill, potentially harming wildlife. To mitigate these potential issues, it is recommended to explore alternatives such as industrial effluent reuse and recycling, which can help minimize the environmental and ecological impacts.
