12-10: Field Evaluation and Verification of Biological Control in Operating #N/A

12-10: Field Evaluation and Verification of Biological Control in Operating #N/APulse Electric Field Devices (PEFDs) have been used as the sole source of water treatment in evaporative cooling water systems for over 10 years often with good results. Several field evaluations will be presented that provide detailed data on microbiological control entirely by the PEFDs. This paper will present both field and laboratory test data independently obtained from operating cooling tower water systems that rely solely on PEFDs for

Our studies demonstrate a need to revisit current biocide dosing practices in order to meet the new guidelines for Legionella control in industrial water systems

This paper describes the application of an innovative biodetergent technology to complement conventional biocide programs for fouling control

The cooling water treatment program is designed to control CaCO3 scaling at Langelier Saturation Index values approaching +3

but can be adapted to also test hybrid/parallel condensing systems

This guideline covers the repair of wood cooling towers using replacement pultruded fiberglass structural members

This paper presents and discusses various factors and topics that have an influence upon the sustainability of a cooling system

The method has been proven reliable for determining viable cell concentrations of Legionella pneumophila

Freezing ice on coils is a slow and transient process that hinders the deployment of ice thermal energy storage systems for large commercial buildings

operating motors on adjustable speed drives

Biological attack is the more serious type of attack and is difficult to detect

especially in the high pH environments common to many of today's cooling water systems
