the earth diatomite is a material used by the industries in the filtration process and clarification of the beer. this material presents a reduced useful life due to the blockages of their pores during the filtration process. the objective of this work was to reactivate the properties of filtration of the earth diatomite, saturated with organic matter during the filtration stage, starting from a controlled thermal treatment. the obtained results demonstrated that the earth diatomite saturated with organic matter submitted to a controlled thermal treatment has their filtration properties reactivated, could be reused in the beer production process.
