Ground kenaf core as a filtration aid
2001
Lee, S.A. | Eiteman, M.A.
The objective of this study was to examine the filtration characteristics of ground kenaf core, a waste material generated during the production of kenaf bast fibers for paper. The constant-pressure precoat filtration characteristics of ground kenaf core were compared to commercial diatomaceous earth (DE). Three challenge solutions were studied: a yeast solution, a bacterial solution, and a standard silica-particle solution. The kenaf and DE both satisfactorily permitted removal of all silica particles from solution without noticable flux degradation over the course of the filtration. The kenaf and DE also removed yeast particles. In this case, the flux loss with time was lower with the DE precoated filter than in the kenaf precoated filter. The DE precoat excluded less than 10% of the bacterial particles from solution, whereas the kenaf removed about 40% of the these small particles.
