(2006)
IPPTA Seminar & Conference
- Abstract
- Membrane technology is a relative new technology in the pulp and paper industry with interesting applications in the water loop, the by-product loop and the chemical loop. The technology was pioneered in the pulp and paper industry by DDS Filtration, now Alfa Laval Nakskov in the 1970’ies and this article reviews the opportunities to use membrane technology in the different loops investigated over the years. The first part of the article focuses on the water loop and demonstrates the use of membrane technology to (1) prepare and purify in-take water, (2) recycle water in processes, and (3) to treat water before discharge. For the water loop, the use of membrane technology to polish evaporator condensate will be given as an application... (More)

For the water loop, the use of membrane technology to polish evaporator condensate will be given as an application study. In the second part of the article membrane opportunities in the by-products loop of the sulphite and Kraft pulping process will be highlighted. The use of membrane technology for the concentration and purification of spent sulphite liquor in a sulphite pulp mill will be described in application study. The final part of the article will discuss membrane applications in the utilities and chemicals loop. The use of membranes for the Kraft bleach purification and for the paper coating recovery will be presented. Further, an application study will detail the use of membranes for purification of Kraft bleach effluent. Overall, the paper demonstrates potential of membrane technology for the pulp and paper industry ranging from water purification and preparation to the recovery of valuable products. (Less)
