04-08: Update on the Impact of Water Immersion for Pultruded FRPThe development of CTI Standard 137 generated some questions regarding the performance of pultruded structural shapes in a water immersion environment. No data existed for pultruded Fiberglass Reinforced Plastic (FRP), but there was some concern regarding a reduction of properties. Three pultruders who supply the Cooling Tower Industry with structural shapes submitted samples for a water immersion analysis that has been underway with periodic testing

The demand for high-quality water

Dosage optimization requires sounds mathematical models for inhibitor dosages

In those cases where the cooling tower section and impeller is too big for testing it’s suggested to test a scaled down replica or do in situ testing

if it does not cool the water to the specified conditions

The results of weight gain

Hydrocarbon ingress to the cooling water requires novel approaches to control microbiological fouling

Complying with increasingly stringent water discharge limitations has forced a re-examination of current cooling water treatment practices

This could become a Pandora’s box if we are not careful

But how many of us realize what goes on behind that faucet handle

My subject is Review of Thermal Pollution Problems

This paper addresses these questions provides cost justifications

Pitting corrosion of pumps
