90-05: Estimating Operational Service Time of Heat Exchangers Cooling Tower Water Treatment Programs rapid bioassay and an on-linePredicting operational service time of heat exchangers between forced maintenance outages is a subject, which has been studied intensively for many years. Numerous technical and economic advantages would occur if such predictive data were available, to permit appropriate preventive actions to control potential fouling problems developing on either the cooling water side or the process fluid side. The calculation methodology developed by Kern and other
