93-10: A New On-Line Monitoring and Control Capability for Cooling WaterA new monitoring and control process has been developed which measures active treatment components in current cooling water treatment programs. This system incorporates a sensing device with a controller to monitor and control product federate. This sensor is superior to currently available technologies that either utilize automated wet chemical methods or measure product levels indirectly. Laboratory and field case studies will be discussed.

The efficiency of the drift eliminator is governed by the channel orientation and geometry and by the air flow rate

We have focused on controlling amoeba-amplified forms of Legionella by various biocide regimes commonly used in water treatment and provide proof for a hypothesis that explains the inability of conventional treatments in controlling these hardy and relevant forms

To prevent calcium scaling

In order to avert such safety incidences during Cooling Tower maintenance

standards or guidelines

various pollution agencies have been setting standards on chromate discharge levels in cooling tower blowdown

splash fills

The cleaning and diversion while maintaining tower operation and plant operation has never before been attempted anywhere in Canada and is possible the first ever done anywhere in the world

In cases where calcium is the blow-down determining constituent

A summary of these events will be discussed in this paper along with the probable reasons and actions AEP is taking to prevent a reoccurrence

A case study of a cooling tower installation in a refinery will be presented
