76-13: Electrochemical Destruction of Chromate and Zinc From Cooling Tower #N/A

76-13: Electrochemical Destruction of Chromate and Zinc From Cooling Tower #N/AChromates are generally destroyed to trivalent chromium by addition of chemical reducing hydroxide sludge that can be readily removed from the waste stream. Sulfur dioxide and ferrous sulfate are the reducing agents that are commonly used. Alkalis, such as slaked lime, sodium carbonate, or sodium hydroxide, are commonly used for precipitating trivalent chromium. Other methods reported in the literature for the destruction, removal, recovery, or reuse

such as slaked lime

produces a real hazard

consumption of energy in the

the overhead condenser and a dollar cost which could easily pay for

and nutrient availability

This paper explores a number of new products

A study was recently completed in an effort to answer this question using actual first cost and full load performance data from a variety of chiller

The lab performance evaluation

Along with laboratory data

low maintenance

an adiabatic fluid cooler or refrigerant condenser) is the best solution to balance costs

Recent advances in quartz crystal microbalance technology provide valuable insight into the effects of temperature
