SOME PRACTICAL AND ECONOMIC ASPECTS OF USING HIGHLY CONCENTRATED LIQUID BROMINE BIOCIDES IN COOLING WATER TREATMENT

摘要

Recent advances in process chemistry have lead to the development of a new generation of single-feed liquid bromine biocides. Highly concentrated stabilized bromine biocides permit the rapid establishment of target residuals. This feature is utilized in a number of case studies for the eradication and control of assorted algae in cooling tower water. Shock dosing to lethally high bromine residuals (> 5 ppm as Cl_2) is accomplished quickly and efficiently so that minimal product is wasted in the blowdown.
