Microorganisms can wreak havoc in industrial processes in a number of ways – from slime formation that causes paper breaks and excessive downtime in papermaking facilities, to costly recalls of spoiled final product. Consequently, an effective microbiological control program, which includes accurate and reliable monitoring, is critical for maintaining an efficient process and final product quality. Many industrial process operators use culture tests or 1st generation devices – such as ATP pen-style tests – for portability and convenience, but these tests are susceptible to issues related to variability and interferences. 2nd Generation ATP tests are also portable and convenient but provide enhanced resistance to interferences and sensitivity through more complete extraction of ATP. For this reason, 2nd Generation ATP is a preferred choice as the first line of defense against microbiological growth and can be used effectively in a variety of testing programs, such as routine monitoring and biocide and biofilm dispersant performance assessments.
