19-05: A Fouling and Thermal Performance Test Rig for Cooling Tower Fill Non Oxidizing Biocides

19-05: A Fouling and Thermal Performance Test Rig for Cooling Tower Fill Non Oxidizing BiocidesEskom's coal fired power stations mostly have natural draft wet cooling towers, where excessive fouling results in maintenance and performance issues. Eskom is planning to replace the asbestos fill in selected cooling towers, and needs to evaluate potential replacement fills. A set of four test rigs have been built that simulate conditions within a natural draft wet cooling tower. Water tapped from a cooling tower is used in the test. Both the fouling

Nalco was awarded DOE grant to develop a cost-effective integrated solution (chemical and physical) for the use of impaired water and maximize the cycles of concentration

This paper reviews five problem solving techniques in order to solve the following problem: "Why are copper corrosion rates as measured by coupon so high in recirculating cooling waters

fouling which occurs on the process side is determined more precisely

The technical paper will be about removing sludge and cleaning cooling tower basins while the tower is procedures

ATP-based testing methods offer immediate results and measure the total microbial population

Users should apply these guidelines as part of the decision-making process

The purpose of this paper is to detail the activities which took place before and during the reconstruction of the (2) cooling towers of Unit #3 during the months of October and November of 2005
