Enhancement Wastewater Treatment in Aluminium Extrusion Process Using Single-Effect Distilation with Spray Atomization

Abstract
Improper discharge of industrial wastewater poses a significant environmental challenge, particularly in industries such as aluminium extrusion processes which generate effluents containing strong acids, alkalis, chromium, and heavy metals. These hazardous contaminants require effective treatment to prevent environmental pollution. This study investigates the feasibility of employing a Single-Effect Distillation (SED) system as an innovative solution for wastewater treatment. The SED process not only harvests clean water but also minimizes the reliance on external chemical agents, offering a more sustainable approach. A novel spray inlet mechanism was integrated into the SED setup to enhance performance. This mechanism atomizes the incoming wastewater stream, significantly improving heat transfer efficiency within the evaporation chamber. The resulting enhancement increased the freshwater production rate by up to 24%. The quality of the distilled water was rigorously analyzed to ensure compliance with municipal discharge regulations, demonstrating the system's capability to produce safe, high-quality effluent. This research highlights the potential of SED technology, augmented with spray atomization, as a promising and environmentally friendly method for treating wastewater from aluminium extrusion processes while contributing to water conservation and pollution mitigation efforts.
