Natural organic matter and sulphate elimination from rainwater with nanofiltration technology and process optimisation using response surface methodology

In the current study, the effect of operating conditions including membrane characteristics and applied pressure on natural organic matter and sulphate removal of nanofiltration (NF) membranes for drinking water production was investigated. Water stress has been increasing all over the world due to...
