05-19: Effective Chemical free Microbiological Control for Industrial CoolingEffective microbiological control is a critical component to optimizing efficiencies in industrial cooling water systems and oftentimes the most difficult to achieve and maintain. Due to a wide range of reasons involving environmental discharge issues, worker safety concerns, storage, troublesome feed equipment, and impact on system metallurgy, the selection and or application of micro biocides is becoming typical. A novel non chemical means of

Mechanical Draft

Although this paper is only indirectly related to the subject of this symposium and is being delivered by a biologist with little knowledge of cooling towers

to high time-dependent load variations causing high vibration amplitude and high stress

This paper will discuss the analysis of these waters and instrumentation that allows careful monitoring to be achieved

Case studies of field trials will be discussed as well as benefits and details of the new feed system

As part of the analysis

location of louvers

it will show how the various switches meet or do not meet the new CTI Vibration Standard

chromate treatment for corrosion control is preferred

The cooling towers of EDF NPP are located in various places fed by rivers

The problem has been solved with two cells concrete cooling tower in the Czech Republic where only simple maintenance was planned

This paper discusses the main problems and risks associated with the use of reuse water in an oil refinery
