Beer microfiltration under conditions of hydrodynamic instability at the “membrane - product” interface

Abstract

Abstract The basic principles and practical implementation of methods for beer media microfiltration processes intensifying due to the creation of hydrodynamic instabilities in the near-membrane zone of the membrane device were considered. Prerequisites for the development of membrane devices with a concentration polarization low level were also studied in the work. The creation of hydrodynamic instabilities in the near-membrane zone is provided with their help. This is achieved not only due to the installation of various design turbulizing devices in the membrane module channels, but also due to their operation according to a specific algorithm interconnected with the membranes specific permeability. This algorithm should certainly allow to influence the high-concentration near-membrane layer with varying degrees of intensity and cause no deviations from the quality indicators of the processed liquid food media.
