Diatomaceous Earth Process

Diatomaceous Earth - an overview ScienceDirect Topics

Diatomaceous earth has various advantages for filtration in the brewing process as reported by Baimel et al. (2004). The conventional dead-end filtration with filter-aids (Kieselguhr) has been the standard industrial practice for more than 100 years and will be increasingly scrutinised from economic, environmental and technical standpoints in ...
