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.
其中一种环境污染是由工业废水排放引起的，需要进行充分过滤。由于制革工业废水含有高浓度的铬、重金属、油脂和硫，因此它是最具破坏性的废水处理之一。本实验研究专注于反渗透和混合有机聚酰亚胺膜用于纳滤的可持续废水处理。在 RO 和有机聚酰胺纳米多孔膜中，使用了薄的聚酰胺膜用于高效过滤。田口分析优化了工艺参数，如压力、温度、pH 值和浓缩倍数。结果表明，总废水硬度降低了 89%，硫酸盐降低了 88%，COD 去除率提高了 89%。因此，所提出的技术显著提高了过滤效率。
