This study introduces a pioneering ceramic membrane-based produced water treatment technology (CMPWT) and validates its efficacy by treating a carwash water sample sourced from Al-Ain, situated in the Abu Dhabi Emirate, United Arab Emirates (UAE). A carwash sample procured in May 2023 from a local car washing facility in Al-Ain City served as the basis for this investigation. Utilizing the dead-end filtration mode with a filtration rate of 3 m3/m2/d, the transmembrane pressure peaked at approximately 30 kPa (temperature normalized to 25 °C). Air blowing was employed to counteract this pressure buildup, resulting in a substantial reduction of approximately 5 kPa. Within a span of 1 h, the total suspended solids (TSS) in the water decreased remarkably from an initial concentration of 489 mg/L to a final concentration of 2 mg/L. Comprehensive water chemistry analysis revealed a composition primarily comprising Cl–HCO3–Na–Ca in the carwash wastewater. This study underscores the remarkable capability of CMPWT to efficiently reduce the TSS in carwash wastewater. The treated water stands are poised for safe discharge into the environment without causing harm or, alternatively, for potential reuse within the same facility. This technological advancement addresses the pressing need for effective wastewater treatment solutions and underscores its potential for broader environmental and industrial applications. The successful deployment of CMPWT in this context marks a significant step forward in sustainable water management practices, particularly in arid regions such as the UAE, where water conservation and quality are paramount. By providing tangible evidence of its effectiveness in real-world scenarios, this study provides valuable insights into the ongoing discourse surrounding wastewater treatment technologies and their implications for environmental sustainability and resource management.
