01-01: Water Reuse in refineries, Chemical Plants, and Utilities: ExperiencesWater reuse has been successful and cost effective in cooling water and boiler water systemswhen properly planned and matched with system operation and materials of construction. Specific guidelines are provided for cooling and boiler water systems and treatment requirements. Case histories throughout the USA and Texas illustrated specific experiences and results in system protection.

We have focused on controlling amoeba-amplified forms of Legionella by various biocide regimes commonly used in water treatment and provide proof for a hypothesis that explains the inability of conventional treatments in controlling these hardy and relevant forms

Construction contacts on field erected cooling towers have two major types of cost: fixed and variable

elevating the exposure

It may not only be beneficial but imperative to remove these containments upstream of the cooling tower

Results were recorded and compared over a period of time

Shutdown periods for inspections are costly and often only a short time period is available

This code is similar to the open circuit tower in both form and function except for the fluid circuits

A model for the calculation of drift deposition from salt water cooling towers has been developed

These waters often contain impurities that serve as nutrients for microbiological fouling in cooling systems

Legionella testing is required and chlorine residual control ranges are specified

operation and treatment of open evaporative cooling systems are discussed

these approaches can be used to study corrosion of other metals or to evaluate any other problem
