15-04: The Impact Of Ionic Strength Upon Inhibitor Speciation and EfficacyDosage optimization requires sounds mathematical models for inhibitor dosages. Frequent questions include: What test methods should be used to develop scale inhibitor performance data? How do you determine "end points" where scale inhibition is lost? What experimental design matrix should be used to prepare test conditions? How are failure points determined? This paper addresses these questions and describes recommended test methods for evaluating

and the establishment of protective measures allowed for successful reuse of this stream at minimal risk

soluble silica

and financial/operational savings in the variations required to address small

Pultruded profiles offer many positive attributes

and ways to avoid or minimize iron rot

The recirculating water contained 500 ppm each of calcium hardness and total alkalinity (both as calcium carbonate) at either 105 or 130 degrees Fahrenheit

is described

either below or above the fan in a cooling tower

Certification capacities by the CTI assure the tower purchaser of full performance without the need for field-testing

A temporary heat source was used

Increasing the heat transfer coefficient reduces the necessary heat exchanger size

What is the universe of factors that affect a cooling system and how do they affect successful long- term maximization of system performance and minimization of deterioration and premature failure
