- Beer clarification commonly is accomplished with a
batch-filtering media called kieselguhr, which is a silica that can pose a
health hazard. At an Asian brewery, Hyflux’s InoCep ceramic hollow fiber
membrane replaced kieselguhr and yielded a high quality beer, according to the
- Juice clarification mainly is concerned with eliminating the
constituents responsible for the turbidity and cloudiness found in freshly
produced juice. A conventional filtration method in the clarification process
includes filtration through plate-and-frame and rotary vacuum filters. However,
the final product often is left with a higher level of undesired constituents
than what is preferred by industrial standards. A South American engineering
services company has employed InoCep ceramic membranes for fruit and vegetable
juice clarification processes for industrial-scale projects. Sharp pore-size distribution
and hollow-fiber configuration delivered high flux without compromising
standards of organic acids or vitamin content.
- Fermentation broth made at two plants in China use Hyflux’s FerroCep stainless steel tubular membrane for clarification and simplified their traditional process. The clarification device improved yield and reduced production costs by eliminating redundant process stages like flocculation, coagulation, plate-and-frame filter and centrifugal separators.
Using Hollow Fiber Membrane for Liquid Clarification
Separation company Hyflux Ltd., Singapore, has had lots of experience with liquid clarification from beer to broth. Here are bite-sized case histories for easy consumption.
