A novel, single-stage Pressure Assisted Osmosis system demonstrating broad-spectrum removal of anionic and cationic contaminants from water is described in this article. The system has demonstrated a high removal efficiency of over 95% for anions such as sulfate and cations such as calcium and magnesium. It has also demonstrated a removal efficiency of over 90% for monovalent anions such as carbonate and chloride. The modular system is characterized by a high degree of process intensification. The portable set-up attempts to merge several parts like feed cells, membrane assembly, and external force media into one compact unit. Another design feature was the operational flexibility of mechanical force addition. The portable device demonstrated sustained solvent flux without the usage of electric power. The proof of the concept of experimental studies with operational aspects like reverse salt diffusion is described in this work.

本文介绍了一种新颖的单级压力辅助渗透系统，该系统可从水中广谱去除阴离子和阳离子污染物。该系统已证明对阴离子（如硫酸根）和阳离子（如钙和镁）的去除效率高达95％以上。它也显示出对单价阴离子（例如碳酸盐和氯离子）的去除效率超过90％。模块化系统的特点是高度的过程强化。便携式装置试图将多个部分（例如进料池，膜组件和外力介质）合并为一个紧凑的单元。另一个设计特征是增加机械力的操作灵活性。便携式设备显示出持续的溶剂通量，无需使用电源。
