87-14: Corrosive Water - A Brazilian RealityIn 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

the timing is right to review the capability of these new motors in cooling tower applications

New experimental data and a comprehensive bibliography are included

The removal of such scales is often a complex mechanical or chemical process and the up-front prevention of their formation is a much desired solution to the problem

Instrumentation and techniques

how it is handled

can present problems not found in modifications or additions to existing systems

and the buckling and joint strength of pultruded tubes were evaluated

water chemistry and operational changes

in conjunction with a chromate corrosion inhibitor package

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

Combining Controlled Hydrodynamic Cavitation treatment with filtration and process controls provides a complete solution for treating cooling tower water that: lowering operating costs

This paper describes a new chemistry based toolset that enables power industry personnel to build inexpensive yet sophisticated water balance models that are extremely useful for evaluating water saving alternatives
