TP26-16 Demystifying and Recognition of Direct and Inderect Mic Mechanism and Contribution to Localized Corrosion in Water Systems Water Reuse

TP26-16 Demystifying and Recognition of Direct and Inderect Mic Mechanism and Contribution to Localized Corrosion in Water Systems Water ReuseThe paper will discuss the finger prints associated with direct and indirect microbiological influenced corrosion (MIC); thus, allowing for the assessment for potential MIC activity that has influenced the corrosion rates and type of corrosion detected. All fouling, except inorganic scaling from insitu crystallization, lead to localized corrosion. As a result, many inspections of surface corrosion can be misdiagnosed as to the cause of such corrosion

Results indicate that elemental content in drift water (mineral residue) may not be equivalent to the content in the recirculating cooling water of the tower

A DuPont plant has experienced severe localized corrosion from a complex corrosion phenomenon in its cooling water system

The non-chemical technology was evaluated for control and prevention of corrosion

Water is vital to industry in processing raw materials

Asset preservation is a major priority among utilities and communities

and test methodology used to assure accurate performance predictions

This paper provides insight into key considerations for these large cooling tower installations

These solids can originate in the process

is defined as surface-associated microbial heterogeneous structures comprising different populations of microorganisms surrounded by a self-produced exopolysaccharide matrix that allows their attachment to inert or organic surfaces

are considered critical

Two fans have been selected for qualification together with quiet drive equipment

but few studies have been published on the modeling of corrosion and its inhibition in aerated cooling water systems
