12-10: Field Evaluation and Verification of Biological Control in Operating Fans & Associated Equipment and what materials and processes

and what materials and processes give the best results

The second phase

Cooling tower water distribution piping is typically designed for normal water flow rates and low operating pressures

rather than a primary control output

Control of water treatment chemistry utilizing instrument measurement of system water flow and cycles of concentration provides precise control of chemical additives

12-10: Field Evaluation and Verification of Biological Control in Operating Fans & Associated Equipment and what materials and processesPulse 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
