Membranes make efficient emulsions more easily
15 Jan 2000
In collaboration with Disperse Technologies, Fairey Industrial Ceramics and the University of Exeter, Memtech (UK) has introduced a new crossflow membrane system for the industrial scale production of emulsions.
In comparison with conventional techniques, the system is said to use very low power, yet provides better control over droplet size distribution.
By using a tubular ceramic membrane, the droplet-forming phase is driven into the recirculating continuous phase, enabling uniform droplets at high density to be obtained in batch or continuous mode. The narrow size distribution obtained by this method means that very specific properties can be built into the emulsion, which should interest the cosmetics, toiletry, pharmaceuticals and food industries.
