Removal and Fouling Mechanisms in Nanofiltration of Polysaccharide Solutions
Tubular membrane filtration is an important process when feed waters with a relatively high solids content are filtered. Such solids would normally have to be removed in a pre-treatment stage if spiral wound modules are to be used. High solids content occurs for example in high turbidity surface waters, wastewaters that contain fibrous materials or in waters where coagulants are added. Tubular ...

متن کاملMembrane fouling in the nanofiltration of landfill leachate and its impact on trace contaminant removal
Nanofiltration (NF) is an attractive option for the treatment of landfill leachate. However, membrane fouling can be a major obstacle in the implementation of this technology. In this study, bench-scale filtration experiments were carried out to study the fouling behaviour during the NF of a synthetic landfill leachate. The results indicate that calcium in combination with organic matter could ...
متن کاملRemoval of textile dye from aqueous solutions by nanofiltration process
The feasibility of employing nanofiltration (NF) in the decolorization of ionic (direct blue 86) and nonionic (disperse blue 56) dye aqueous solutions was investigated. The effects of feed concentration (60- 180 mg/l), pressure (0.5- 1.1 MPa) and pH (6- 10) were studied. Experiments were performed in a laboratory- scale set up by using a TFC commercial spiral wound polyamide nanofilter. The res...
