10-18: Oil-In-Water UV Fluorescence Sensor In Cooling Tower And OtherIn order to simplify and accelerate the analyses of oil and grease in industrial waters, particularly used in cooling water in heat exchangers, a UV fluorescent sensor sensitive to polycyclic aromatic hydrocarbons (PAH) being part of refined oil products was tested. The testing was also conducted in several applications involving wastewater treatment and confirmed a relationship between oil in water concentration and content of the PAH. While

Depending on the elements to be surveyed

Chromates are generally destroyed to trivalent chromium by addition of chemical reducing hydroxide sludge that can be readily removed from the waste stream

Such data are helpful in evaluating the economic trade-off between improved tower performance and increased costs of a more efficient air movement system

EDF decided to run two campaigns of tests: the first one focused on the effect of the mechanical deterioration of drift eliminators

Unlike the cooling tower flow

and significant scatter in results have been reported

The resulting data have allowed us to develop a simple kinetic model comparing performance of the additives under various conditions and these results have provided us with direction for potential process improvements with reduction in scale formation

reduced heat transfer

Microbiological growth on cooling towers

but theses recommendations can also be modified for seasonal storage

Through contact with water

The consumptive use of water is of concern to us -- for plants that use cooling towers (the practical alternate method to using stream or reservoir water) use more (consumptive) water per kilowatt hour generated than do plants which are able to circulate their cooling water in lakes
