Domestic water sources in rural areas could be polluted by ammonium, nitrite and nitrate. These compounds affected to human health. Therefore, development of membrane filtration system to control the above pollution parameters is essential. In this study, a lab-scale membrane filtration system was operated under various conditions to evaluate the removal efficiency of ammonium, nitrite, nitrate. Several operating parameters such as flow, pressure and membrane resistance were also determined. The obtained results showed that the membrane filtration system achieved stability at the permeation and concentrated recovery ratio of 40%/60%. The removal efficiencies of ammonium, nitrate and nitrite were found at about 72.8%, 85%, and over 90%, respectively. The treated water could be met national regulation (QCVN 01-1:2024/BYT) for domestic purpose. In conclusion, developing a small-scale membrane filtration system could be suitable for households in rural areas which were lack of water treatment infrastructure.
