87-14: Corrosive Water - A Brazilian Reality Mechanical Draft Towers

87-14: Corrosive Water - A Brazilian Reality Mechanical Draft TowersIn Brazil, for the majority of open recirculating systems, make up water contains a low dissolved solids index and its main contaminants are aluminum and iron. The first one derives from raw water clarification process leakage; the latter may have the same origin and or may be a product of equipment and lines corrosion. Iron and aluminum form a compound of low solubility product that may seriously affect the heat transfer. Considering these

It does not set the heat load

This paper explores a number of new products

These systems

By using an electrical braking technique

Cooling towers are not one size fits all and are therefore designed and built to achieve a specific amount of cooling at a predetermined water flow

and steam velocity profile on heat exchanger tube erosion using CFD

chromate-based corrosion inhibitors were widely used in open cooling water recirculating systems

when the testing of the fan is impractical

and changes in fan characteristics

This paper describes a novel

This paper will present the results of laboratory test to study effect of novel chemicals on in vitro cultures of filamentous bacteria

In this paper the author discusses many of the common control/treatment schemes and provides both a theoretical basis for each program and practical guidelines on their performance and imitations
