METHOD AND APPARATUS FOR MONITORING PARTICLES IN A LIQUID

摘要

Particles in a liquid flow are monitored by reflected light fluorescence. The flow may pass through a flow cell (10) having a viewing window (14). The flow cell may be partitioned by a membrane (12) so that deposition of particles can be monitored. The use of reflected light fluorescence enables the monitoring of small particles (under 3ųm) which are important in the fouling of membrane surfaces in membrane bioreactors, but which are undetectable by conventional direct observation methods.
