Increasing flux by back-pulsing in the microfiltration of milk
(2015) In International Dairy Journal 41. p.23-25- Abstract
- Milk with extended shelf-life can be produced by microfiltration (MF) and pasteurisation in a cascade arrangement. In a previous study, we have shown that back-pulsing can be used to reduce the energy requirement in the MF of defatted milk. In this study, the influence of back-pulsing on MF was investigated at higher milk fluxes than in a prior study. The MF experiments were performed in constant-flux mode. The operational time until a certain pressure build-up was used as a measure of the performance. Fluxes between 350 and 500 L m−2 h−1 were investigated, with and without back-pulsing (frequencies ranging from 6 to 0.2 min−1). It was shown that the fouling rate was strongly dependent on the permeate flux; higher flux leading to a higher... (More)

Improved MF performance was found using back-pulsing at a flux of 350 L m−2 h−1, while at higher fluxes, back-pulsing impaired the performance. (Less)
