Abstract
A particle detection system uses a camera to produce a picture based on the scattered light generated by a particle in a liquid medium, when a laser beam is incident on the particle. These pictures are then automatically analyzed through the use of a processing system (e.g., a computer). The processing system is configured to record the forward scattering intensity (e.g., amplitude) and the picture of the scattered light rays to generate a classification of the particle causing the scattering. Count rate and trends of the classified particles are monitored to detect a change that is representative of the overall health safety of the water or by knowing the levels of bacteria in process water, such as Reverse Osmosis (RO) feed water, reject brine, and product water, the operator may better monitor the life and condition of the RO membrane.
