77-19: The Reduction of Chromate by Amine Phosphonates at a Low pH Legionella

77-19: The Reduction of Chromate by Amine Phosphonates at a Low pH LegionellaDuring the last ten to fifteen years, major advances have ocurred in the technology of cooling water scale and corrosion inhibitors. One of the most significant advances started during the middle 1960's when the organophosphates were introduced commercially. These materials won rapid acceptance in industry because of their strong threshold effect and their high level of hydrolytic stability.

A summary of these events will be discussed in this paper along with the probable reasons and actions AEP is taking to prevent a reoccurrence

and/or economic benefits (reduced operating costs)

its proper application has several hidden pitfalls that must be considered when specifying the motor control and mechanical components in the system

reduced energy

There is no doubt that a need exists for a simple

both laboratory and field performance data will be presented

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

The reports come from various sources: end users

The simplified awl penetration test commonly used by contractors during inspections of wood cooling towers would be more reliable if penetration data were correlated to mechanical properties

An additional spray nozzle will be presented here to extend the working range of full cone nozzles

we speak on the subject of building a maintenance program for your FRP blades for cooling towers
