05-13: Evaluation into the use of Mine Drainage to Supplement Cooling Water Non Oxidizing BiocidesThe Sasol petrochemical complex located in Secunda, South Africa operates the world's largest coal to synthesis gas conversion process. Expansion projects have resulted in an increase in cooling water requirements which is difficult in this water short catchment. Conversely, drainage water continuously accumulating in old coal mine workings is a growing liability. In an effort to balance the supply and demand within the complex, investigations were
and fungal) in the biofilms that develop on cooling tower slats
particularly our electric utility companies
Other significant geometrics have now been lab tested and field evaluated with outstanding results
When I was asked to talk to you on the subject of our environment
The company Special Water Europe BV and the KEMA Institute set out to test the effectiveness of the additive the Cool Puck in its laboratory using a small scale test assembly based on the Dutch Standard for assessing the performance of treatment programs for open re-circulating cooling tower water systems
sound level measurements were carried out during the night
Recent environmental concerns have been expressed regarding the possible toxicity effect to aquatic life from copper in once-through cooling water discharge and the blowdown from recirculating cooling systems
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
The amounts of water required for cooling depend on the temperature of the cooling water and the particular use
Additionally updraft air velocity and waterflow measurement results are provided
Proper attention to cooling water systems operating and control parameters
Case histories of actual cooling water applications are discussed which show when and where molybdate-based products have outperformed other
