12-24: Novel, Mild Oxidant Improves Cooling Water Treatment PerformanceA low system oxidation reduction potential (ORP) is desirable to minimize corrosion in recirculating cooling systems. Traditional oxidizers, however, are ineffective at system ORP less than 400 mV for neutral to alkaline pH values. This paper describes a novel, proprietary biocide that is marketed as Biosperse XD3899 microbiocide and made from the stoichiometric reaction of sodium hypochlorite and ammonium bromide. The resulting active, bromide

this paper reports on the successful combination of the latest state-of-the-art analytical procedures with advanced programming techniques and extensive laboratory testing to create a workable and powerful engineering software package for evaluating the thermal performance of large closed-circuit cooling towers

the use of wastewater as a source of cooling tower makeup water can result in significant corrosion

Recent studies have highlighted the advantages of hydroxy phosphono acetic acid (HPA) based formulations compared to those of other phosphonates

Mast Climbing Work Platforms (MCWP’s) are becoming a popular method of access in the demolition and repair of cooling towers and stacks throughout the USA
