85-03: Cooling Water Treatment Transition Zinc-Chromate to All OrganicDescribes the transition made at a major southwestern chemical plant from zinc chromate to an all organic treatment program. Information is provided on the comprehensive program that was instituted to ensure positive results. A major portion of that program involved the use of a computerized fouling monitor. Results of the all organic program, including cost differentials, are included.

Factors that affect the durability of concrete cooling tower structures

Predictive Maintenance (PdM) can be a key ingredient in the successful implementation of an effective Asset Management program

particle diameter

This independent evaluation was monitored for over 11 months utilizing corrosion coupons

The size is also controlled to a large extent by the required air circulation in the tower

the past three decades could rightfully be called the "age of Plastics"

very few coolant tower systems employ ion exchange

The recycle and reuse of waste and process water streams can turn potential environmental problem discharge streams into beneficial cooling tower make-up streams

Two related case studies are presented

The Denver Water Board has initiated a cooling tower water audit program
