Sustainable pretreatment and adsorption of chemical oxygen demand from car wash wastewater using Noug sawdust activated carbon.

ABSTRACT: Wastewater treatment in developing countries remains inadequate due to limited awareness of its environmental and health impacts, coupled with the high costs of available treatment technologies. Therefore, developing cost-effective, accessible, and efficient treatment solutions is crucial for protecting public health and the environment. This study evaluates the chemical oxygen demand (COD) removal efficiency of a novel combined pre-treatment process followed by adsorption using Noug sawdust activated carbon (NSDAC), a low-cost and sustainable adsorbent. A laboratory-based study was conducted to optimize COD removal efficiency through sequential pre-treatment steps as screening, sedimentation, and filtration followed by adsorption with NSDAC. The adsorbent was chemically activated using su
