METHOD FOR FILTRATION OF A LIQUID, IN PARTICULAR FOR THE FILTRATION OF BEER, USING A FILTER AID

摘要

The invention relates to a filter aid for filtering a liquid, such as beer, ina filtration device working on a defined filtration velocity, said filter aidconsists essentially of particles of a material A, wherein the flotationvelocity UoA is measured as Formula (I): wherein dA is the diameter of theparticle, µ is the viscosity of the fluid, r is the density of the fluidand .rho.a is the density of the particle. The invention further relates tothe use of said filter aid as a precoating material in a candle filtrationdevice and to the candle filtration device comprising a number of candlesprovided with a precoat consisting essentially of the filter aid according tothe invention and to a filtrated liquid, for example alcohol and more inparticular beer, obtained via a filtration method using a candle filtrationdevice.
