TP87-06: Methods for Evaluating the Efficacy of Biocides Against Sessile Bacteria Wood Attack

TP87-06: Methods for Evaluating the Efficacy of Biocides Against Sessile Bacteria Wood AttackDual pilot plant cooling towers were designed and constructed to conduct comparative evaluations of biocides in water systems. The towers were built with instrumentation used to control and monitor environmental parameters. The control of parameters such as pH and conductivity can be used to determine the impact of environmental conditions on biocidal activities. In this paper, we describe the cooling towers and give examples of methods that we have

This list will periodically be updated as new contributions to the literature are made on this topic

an alternative approach was followed

The resistance increases by a factor up to 25 if stagnant film temperature and pressure allows gas evolution to be trapped in the film

Total plant water usage averages 700 GPM

patent-pending

A recurring problem of industrial cooling systems is deposition of particulates brought into the cooling system from outside the unit and those particulates generated within the system

Torque and inertia acceleration capability are also of major concern

This paper compares several methods of connecting fiberglass reinforced pultruded plastic (FRP) structural members to tubular sections using bolted designs that are commonly used in the cooling tower industry

Where to look for

This paper attempts to discuss the proper automatic equipment for controlling the chemical feed and bleed-off of a cooling tower water system

The department tested alternative biocides and is now using an effective low cost biocide

This paper provides guidance for equipment designers to match the water quality with the compatible materials of construction
