文摘
- •
Lager clarification was performed using a novel ceramic hollow-fiber (HF) membrane module.
- •
The quasi-steady state permeation flux was greater than 100 L m−2 h−1 for TMP>2 bar and vS in the range of 4–6 m s−1 in the absence of CO2 backflushing.
- •
The theoretical pump energy consumption was about 66.5 Wh per liter of beer permeate.
- •
The process performance with CO2 backflushing was superior to the industrial polymeric HF membrane processes.
- •
The use of ceramic HF membranes having a 10-yr life span would reduce membrane replacement costs.
