Nowadays, clean water supply demand is increasing day by day in Ho Chi Minh city (HCMC) due to the rapid increase of population. It has gained concerns about water supply management and improving tap water quality of domestic use. Moreover, the results achieved from laboratory analysis of those tap water samples did not comply with the water quality standard due to low pH, high hardness and high ammonia concentration. In order to improve the water quality, low pressure reverse osmosis membrane system was proposed to polish quality of tap water. The pollutant removal of membrane system analyzed on NO3--N, NH4+-N, total Fe, hardness and residue Cl- were 41 ± 17.6 %, 18 ± 16.9 %, 47 ± 26 %, 39 ± 6 % and 94 ± 6.9 %, respectively. The results show that the low-pressure reverse osmosis membrane could achieve effective improvement of water supply quality for domestic use and satisfy the demand of clean water in HCMC.
