Efficiency and Cost-Effectiveness Assessment of Hydraulic Systems for Wastewater Reuse in Agricultural Irrigation

Abstract

Abstract In response to the challenges posed by climate change, this research explores voluntary and planned initiatives for the reuse of treated wastewater, aiming to provide a sustainable water source for various applications. Specifically, the study focuses on the techno-economic aspects of repurposing treated textile wastewater with the use of palm waste filters for irrigation in green areas and cooling towers within the textile industry. Our findings demonstrate multiple advantages in terms of ecology, environmental impact, and technical feasibility associated with treated wastewater reuse. Moreover, the application of palm waste as an alternative adsorbent in the final treatment of textile discharge water exhibits promising results in reducing pollutant levels. The palm waste adsorbents were successfully regenerated through three cycles using an ethanol-water solution. By adopting a water recycling strategy through palm waste filtration, the textile company under study stands to significantly decrease its water-related expenses. This reduction translates from an annual expenditure of 181,542.2 Moroccan dirhams (MAD) to just 9,945.72 MAD, equivalent to an impressive annual savings of 171,596.48 MAD. These findings underscore the economic and environmental benefits of implementing a water recycling system in the textile industry.
