A programme of research has been carried out into the performance of cartridge filters rated
from 0.1 to 0.45 micron in response to steady and varying particle concentrations and water
It was discovered that pulsing the water flow to these filters often resulted in release of particles
which had been previously captured by the filter. For membrane filters the release of particles
was instantaneous. However, for one filter with more depth, a considerable time was required
for most of the particles released to be detected. This filter was described as a pre-filter rather
than a membrane filter. [Continues.]
