88-16: Filamentous Iron Bacteria Diagnosis and Treatment in Water Systems Legionnaires' Disease

88-16: Filamentous Iron Bacteria Diagnosis and Treatment in Water Systems Legionnaires' DiseaseThe paper reviews the literature on the control of filamentous iron bacteria (FIB) and compares some actual field experiences. FIB occur rarely, are often misdiagnosed, and usually have a catastrophic effect, plugging lines and equipment. Prior findings have supported residential chlorination as effective control. Actual case histories in this paper support this approach. Additional information is presented showing that heterotrophic population counts

Environmental considerations in handling and disposal of asbestos materials will be discussed along with the appropriate interface with regulatory agencies

but that means measuring it in some demonstrable way

In discussions involving corrosion inhibitors for cooling water systems

A program is being conducted to identify alternate materials for maintenance of a system of cooling towers

combined-cycle plants operating in a range of ambient conditions characteristic of the State of California in the US

Evidence to support this contention can easily be found-­simply by comparing the gross national product with the kilowatt-hour consumption of electricity through the years

In such situations

The development of twin shaft was definitely possible thanks to extensive tests on the unique Cofimco 38ft test rig that allowed to validate the final solution in the most severe duty points

the calculated results are accordance with tested values at site

they provide no direct information about the effectiveness of the corrosion inhibitor on metal surfaces that have developed a surface layer of rust and oxidation products after several months or years of service

(5) the existence of a legal duty for a chemical treater to warn a premises owner about Legionella
