05-16: Control of Resistant Bacteria in Recirculating Water SystemsBacteria are everywhere in recirculating cooling water systems. Controlling bacterial populations in the bulk water and on cooling system surfaces is necessary to maintain and operate the cooling system properly. Control of micro organisms in the field requires successful application of biocide agents. However, bacterial resistance to biocides is inevitable and irreversible, a natural consequence of bacterial adaptation to exposure to anti microbials.

especially with ammonia applications in the U

elevated temperature capability

water consumption but are susceptible to adverse wind conditions

performance can be engineered through a combination of cooling tower component sizing and heat recovery effectiveness

Non-Chemical Devices (NCDs) have great appeal when talking of the impact of treatment chemicals

as well as by the droplet size distribution

In cooling systems

Four of these modules

A graphic technique is used to show that the amount of calcium carbonite kept in solution by an HEDP phosphonate is a constant

The paper discusses the development and the results

An objective evaluation of common structural materials used in the construction of industrial cooling towers is made
