Microbiological analyses conducted to pinpoint problems in industrial water system, the second type of analysis, are considerabily more complex. a recirculating cooling water system, a paper mill system and waste plant discharge.
In this type of analysis, although total count is a very significant number, by itself it mean little unless samples collected at regularly scheduled times from the same location are analyzed and compared for the levels of populations and species (organisms) normally encountered. The particular analyses shown break down the microbiological life into three categories: bacteria, fungi, and algae. In each category, the specific organisms sought are those that experience has shown to be the most troublesome in industral system.
