- Abstract
Reverse osmosis (RO) and nanofiltration (NF) are effective technologies for removing organic compounds from water. Most research focuses on the removal of organic compounds from water already treated. However, evaluating their removal from groundwater is necessary because coexisting ions affect treatment efficiency. In the case of inorganic compounds, the water's pH, concentration, and membrane charge are the main factors affecting the electrostatic repulsion between the ionic compounds and the charged membrane. This study aims to present the efficiency of removing the studied compounds with NF/RO from groundwater and the physicochemical and chemical processes involved in the removal. As a result of the research, it is found that the hydraulic performance of the membrane, especially for RO, is stable; the efficiency of benzene, ethylbenzene, toluene, and o-, m-, p-xylene removal throughout the research process is at 86% for RO and about 65% for NF.
