ABSTRACT
Paint wastewater poses significant environmental challenges due to its high content of paint residues, which can contaminate water bodies and harm aquatic life. This study investigated a sustainable approach for the recovery of paint from paint wastewater through advanced treatment methods. The research focused on the development and optimization of a novel filtration system utilizing environmentally friendly materials for efficient paint residue removal. The systems employed in the paint recovery involved the use of both physical and chemical processes targeting a cost-effective paint recovery. Additionally, the study explored the potential reuse of recovered paint residues in industrial applications, thus minimizing waste generation and promoting circular economy principles. The proposed approach offers a promising solution to mitigate the environmental impact of paint wastewater while promoting resource conservation and sustainable practices in the paint manufacturing industry. The research findings demonstrated the feasibility and effectiveness of paint recovery from paint wastewater through chemical treatment methods. This included coagulation-flocculation techniques to treat the paint wastewater and also using affordable chemicals to recover the paint as well as using tools and equipment to test for the qualities according to the standards. Further optimization and scale-up of the above coagulation-flocculation method hold promise for broader industrial applications and a greater impact on reducing paint waste and its associated environmental footprint. In conclusion, the proposed paint recovery approach offered a promising avenue for reducing waste generation, conserving resources, and minimizing environmental pollution associated with paint manufacturing and usage. This research contributed to advancing sustainable practices in the paint industry and underscores the importance of adopting circular economy principles for a greener future. Coagulation-flocculation is the most effective chemical treatment method for paint recovery from wastewater. This involved adding chemicals like polyaluminium chloride or polyaluminium sulfate to the wastewater to form reasonable sludge that was then used to recover the paint
