Colloidal Fouling of Nanofiltration Membranes: Development of a Standard Operating Procedure

Fouling of nanofiltration (NF) membranes is the most significant obstacle to the development of a sustainable and energy-efficient NF process. Colloidal fouling and performance decline in NF processes is complex due to the combination of cake formation and salt concentration polarization effects, which are influenced by the properties of the colloids and the membrane, the operating conditions o...

Hemicellulose Fouling Behaviour during Nanofiltration of Press Liquor

Nanofiltration of press liquor from viscose-type textile fibre production was investigated using a laboratory-scale cross-flow test apparatus. Feed solutions contained about 200 g/l sodium hydroxide and a high concentration of hemicellulose as a contaminant originating from the raw material wood. The effect of various pretreatments and the addition of reagents affecting the solution state of he...
