Introduction to membranes: Filtration for water and wastewater ...
The separation spectrum for membranes, illustrated in Figure 1 [based on 3, 4], ranges from reverse osmosis (RO) and nanofiltration (NF) for the removal of solutes, to ultrafiltration (UF) and microfiltration (MF) for the removal of fine particulates.UF can remove the finest particles found in water supply, with the removal rating dependent upon the …
Novel Trends in Proton Exchange Membrane Fuel Cells
DuPont was the first manufacturer of this type of membrane, in the 1960s, while optimizing a Teflon-based material, which led to the discovery of Nafion . The sulfonic acid group SO 3 H in Nafion allows the transport of protons when exposed to water as it changes to the hydrolyzed form SO 3 − -H 3 O +, thus increasing the protonic ...
