High temperature applications of spiral wound modules for UF and NF

Lipnizki, Frank LU orcid and Trägårdh, Gun LU (2004) 9th World Filtration Congress p.20-20
Abstract
The most common modules for ultrafiltration (UF) and nanofiltration (NF) are spiral wound elements due to their low investment, easy replacement and high packing density. Operating at high temperatures greater than 70°C, the use of spiral wound modules is, however, often limited. In the past ceramic membranes have been considered as the only viable option to operate at these temperatures. However, ceramic membranes are still associated with high investment costs. To overcome past restrictions, improved polymeric membranes and spiral wound modules are now available. These new UF and NF modules are manufactured of temperature stable materials, which allow operating at operation temperature greater than 75 °C. Despite the availability... (More)
The most common modules for ultrafiltration (UF) and nanofiltration (NF) are spiral wound elements due to their low investment, easy replacement and high packing density. Operating at high temperatures greater than 70°C, the use of spiral wound modules is, however, often limited. In the past ceramic membranes have been considered as the only viable option to operate at these temperatures. However, ceramic membranes are still associated with high investment costs. To overcome past restrictions, improved polymeric membranes and spiral wound modules are now available. These new UF and NF modules are manufactured of temperature stable materials, which allow operating at operation temperature greater than 75 °C. Despite the availability of these membranes and modules, the influence of the high temperature on the mass transfer performance of the membranes is not fully understood. The aim of this paper is therefore to introduce this new generation of membrane modules and to provide further inside in the mass performance of polymeric membranes at high temperatures. Finally, the use of these membranes will be demonstrated in case study on the concentration of carrageenan, highly viscous sulphated polysaccharides, with UF at 90ºC. (Less)
