06-14: Copper Removal from Cooling Tower Blowdowns Cooling Tower ConversionCooling tower blowdown discharge limits for inorganic metals are being lowered more and more. This paper will document a case of a large cooling tower application in the Gulf Coast that had a 17 parts per billion (ppb) discharge limit placed on it and how ultrafiltration membrane technology was used successfully to lower the cooling tower blowdown copper concentration from 400 ppb to less than 17 ppb.

after 18 years of intense development and production

cooling the water before entering the basin

Performance tests on these two towers are scheduled for the southern hemisphere summer 2004/2005

and safety issues are presented

This paper discusses the effect of elevated water temperatures in these systems and improved methods of treatment

Liquid biocides continue to be a popular choice for control of microorganisms in industrial water systems and numerous treatment options exist in both oxidizing and non-oxidizing biocide categories

These alternate tube designs were analyzed under a variety of flow conditions in controlled settings

Freezing ice on coils is a slow and transient process that hinders the deployment of ice thermal energy storage systems for large commercial buildings

Samples of the cooling water were collected

Also included are observations and experiences for maintaining trouble free operation
