99-16: Unique Biodispersant Removes Biofilms and Increases Biocides EfficacyBacteria in Cooling Water systems must be controlled because bacteria attach to surfaces, forming biofilms that inhibit heat transfer, block fluid flow, promote corrosion, etc. Control is obtained mainly by use of biocides. However, to be effective against biofilm forming bacteria, biocides must be used in high concentrations; however, control is often marginal. In addition, high biocide concentrations may increase toxicity in water in some instances

and short and long term accountability for performance in vendor/user partnership after bid has been awarded

This paper will discuss both the approach to the wastewater pretreatment and the chemical treatment used as the cooling tower

building plants at low cost has been the priority rather than the performance

Cooling towers are fundamental equipment in the industry to remove process heat and cool the working fluid

This report covers the operational results of recycling and blending the recirculating water blowdown with raw makeup water and softening the mixture

few seem to know what they are really getting when they specify preservative treatment in terms of actual protection against wood decay

Revised August 2020

dephlegmator or reflux cell)

giving particular attention to phenomena such as freezing

Cyclonic Filtration has transformed itself to new levels of performance

Quebec Government adopted a Regulation for cooling towers maintenance
