Spiral wound modules for high viscosity solutions at high temperature: Carrageenan concentration with ultrafiltration

Lipnizki, Frank LU orcid and Nielsen, Carl Erik (2003) Filtech Europa 2003
Abstract
Spiral wound modules are the most common modules in the industry due to their low investment and replacement costs plus high packing density. The use of spiral wound modules is often restricted to feed streams with a low temperature (< 75°C) and a low viscosity. The focus of this paper is on a new generation of spiral wound modules, which has been introduced by Alfa Laval Membrane Technology for the treatment of feed streams at high temperatures and viscosity. Key features of these modules are: (1) the use of temperature resistant materials allowing constant operation up to 90°C and (2) integration of an 80 mil feed spacer to process high viscosity products. The use of these spiral wound modules is successfully demonstrated in a... (More)
Spiral wound modules are the most common modules in the industry due to their low investment and replacement costs plus high packing density. The use of spiral wound modules is often restricted to feed streams with a low temperature (< 75°C) and a low viscosity. The focus of this paper is on a new generation of spiral wound modules, which has been introduced by Alfa Laval Membrane Technology for the treatment of feed streams at high temperatures and viscosity. Key features of these modules are: (1) the use of temperature resistant materials allowing constant operation up to 90°C and (2) integration of an 80 mil feed spacer to process high viscosity products. The use of these spiral wound modules is successfully demonstrated in a case study on the concentration of carrageenan, an additive mainly used in the food industry. In this application, the spiral wound modules operate constantly close to 90°C and concentrate the carrageenan in the retentate up to 3-5% while removing impurities with the permeate. Overall, this paper demonstrates the successful application of a new generation of spiral wound modules, which gives the possibility to treat high-viscous solutions at high temperature. (Less)
