82-12: Sewage Effluent Make-Up to Cooling Towers with Film Fill #N/A

82-12: Sewage Effluent Make-Up to Cooling Towers with Film Fill #N/ASouthwestern Public Service Company has two towers operating one sewage effluent make up that have film fill. This paper will look at the water treatment and the operating experience on these towers. One tower has been in operation since 1976 and the other since 1980. The effect of algae and slime on the fill will be discussed.

the filter operational reliability is high and the operation and maintenance costs are extremely low

Shutdown periods for inspections are costly and often only a short time period is available

respectively

Changes in droplet sizes due to evaporation or condensation

This paper will discuss the use of on-line instrumentation

rates of strength degradations are computed for critical components

Case studies will be presented to illustrate condition assessment methods and results

This sensor is superior to currently available technologies that either utilize automated wet chemical methods or measure product levels indirectly

the use of ClO2 was limited to later systems by the capital cost and complexity of on-site generators

This paper summarizes the steps

Maintenance of Cooling Towers usually poses quite a number of occupational/personal safety challenges
