15-18: Alternative to Bromine Improves Cooling Water Microbial Control andAmmonia in the cooling loop poses an additional challenge for Hypochlorite or oxidizing biocides in controlling the microbiological activity since monochloramines are not effective biocides. Historically Bromine based non oxidizing biocides have been an industry standard with occasional Isothiazolin or Gluteraldhyde dosage. This paper discusses how mixed oxidants, as a combination of hypochlorite and peroxide, generated on site replaced non oxidizing

Most corrosion engineers prefer to give the cooling towers

drift eliminators

Several aspects of sustainability apply to cooling systems

regulatory

This has called for converting to surface water supplies and discontinuing the use of ground water

(b) Design Issues

An important distinction between drift and the normally visible condensing plume is that the drift contains the same chemicals and solids present in the circulating water

Drift eliminators are commonly incorporated in wet cooling towers to reduce the amount of water droplet losses

A numerical study was conducted to evaluate design alternatives to alleviate ice accumulation at the river intake

High cycle operation

A code to develop standardized test procedures and evaluation techniques also designed to provide a uniform method to compare relative water treatment program performance in a cooling water system

A sequential study was conducted comparing water treatment performance of traditional chemical water treatment and Dolphin "pulsed power" water treatment
