AI Article Synopsis
- Industrial wastewater from the leather industry is highly polluting due to its high levels of chromium, heavy metals, lipids, and sulfur, requiring effective filtration methods.
- This study explores the use of reverse osmosis and a hybrid organic polyimide membrane for nanofiltration to achieve sustainable wastewater treatment.
- Results showed significant improvements, including an 89% reduction in total wastewater hardness and sulfate, and an 89% efficiency reduction in COD, indicating enhanced filtration effectiveness.
Article Abstract
One of the environmental pollution is happened by the discharge of industrial wastewater that needs to be adequately filtered. Given that the effluent from the leather industry contains high levels of chromium, heavy metals, lipids, and Sulphur, it is one of the wastewater disposals that are most damaging. This experimental study focuses on reverse osmosis and hybrid organic polyimide membrane for nanofiltration for sustainable wastewater treatment. In the RO and organic polyamide Nano-porous membranes, a thin film of polyamide membrane was used for efficient filtration. Taguchi analysis optimized process parameters such as pressure, temperature, pH, and volume reduction factor. The outcome shows an 89% reduction in total wastewater hardness, an 88% reduction in sulfate, and an 89% efficiency reduction in COD. As a result, the proposed technology significantly increased filtration efficiency.
