Continuous monitoring analyzers for waste water require membrane filters to remove small particles. These filters plug up in a few days due to a slime-like growth resulting from nutrients which are present in the waste water. A continuous chlorination system, which supplies a measured amount of chlorine to the suction of the sample pump, eliminates slime growth. The filter life is extended from 5 days to 8 - 10 weeks with no change in analytical results due to the chlorine.
