... the flux and to reduce the amount of chemical cleanings. These conclusions are based on using direct NF with sewage treatment plant effluent and surface water in comparison with the conventional technique: UF as pretreatment for spiral-wound NF. Capillary NF enables raw water to be treated in ...

Contamination of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in surface water of the Yodo River basin (Japan)
The study concerned surface water contamination of two perfluorinated compounds: perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA). Surveys were repeatedl ...

Demonstration of a new hybrid process for the decentralised drinking and service water production from surface water in Thailand
... filtration, followed by activated carbon filtration, was studied in demonstration scale for the drinking and service water production from surface water in Thailand. The main focus of this study centred on the evaluation of the entire process, especially on the membrane reactor technolog ...

... complied with China's drinking water guidelines. The Ames test showed that the mutagenic activities of membrane permeate water was negative. UF of surface water with PAN membranes was proven very useful for drinking water production. Fig. 7. Genotoxic activities expressed as induction factors (TA98).
