Abstract

This research addresses the complexities of treating brackish and seawater from Sungai Itik using Reverse Osmosis (RO), emphasizing advanced pre-treatment methods, hybrid RO systems, and fouling control. Pilot-scale tests confirmed the feasibility of these approaches in meeting clean water standards and balancing economic and environmental sustainability.Using a single ultra-low pressure (ULP) RO membrane, salinity decreased by 57.36%, Total Dissolved Solids (TDS) by 25.76%, and watercolor by 63.25%, achieving improved water quality. Expanding to a ULP and Brackish Water (BW) membrane combination further reduced salinity by 40.63%, TDS by 35.76%, and watercolor by 92.13%, highlighting the benefits of hybrid systems for varied water conditions. In seawater treatment, a ULP membrane reduced salinity by 69.48%, TDS by 93.49%, and watercolor by 97.74%, proving effective for converting seawater to potable or industrial-grade water. Combining ULP and BW membranes achieved salinity reductions of 94.67%, TDS by 94.02%, and watercolor by 34.94%, which is crucial for applications needing ultra-clean water. These findings underscore RO's potential to mitigate water quality challenges and support sustainable water management in diverse environments.

使用反渗透（RO）法在双溪伊蒂克地区淡化咸水

这项研究探讨了使用反渗透（RO）处理来自 Sungai Itik 的苦咸水和海水的复杂性，强调了先进的预处理方法、混合反渗透系统和污垢控制。中试规模的测试证实了这些方法在满足清洁水标准以及平衡经济和环境可持续性方面的可行性。使用单个超低压（ULP）反渗透膜，盐度降低了 57.36%，总溶解固体（TDS）降低了 25.76%，水色降低了 63.25%，从而改善了水质。扩大到 ULP 和咸水（BW）膜组合后，盐度进一步降低了 40.63%，总溶解固体（TDS）降低了 35.76%，水色降低了 92.13%，凸显了混合系统在不同水质条件下的优势。在海水处理中，ULP 膜降低了 69.48% 的盐度、93.49% 的 TDS 和 97.74% 的水色，证明了将海水转化为饮用水或工业用水的有效性。结合使用 ULP 和 BW 膜，盐度降低了 94.67%，TDS 降低了 94.02%，水色降低了 34.94%，这对于需要超纯水的应用来说至关重要。这些发现强调了反渗透膜在减轻水质挑战和支持不同环境中可持续水管理方面的潜力。
