76-09: Environmental Impact of Chemicals Washed From Preservative-Treated Wood Testing

76-09: Environmental Impact of Chemicals Washed From Preservative-Treated Wood TestingTable 1 lists the chemicals and their respective limits that have been set by the Environmental Protection Agency (EPA) and the State of Tennessee for plant discharge. These limits place an impact on the type of water treatment used in the majority of cooling tower water systems. Blowdown from water systems using the chromate or chromate zinc based water treatments must be treated to prevent chromate and zinc from entering effluent.

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

using design data and historical data for the related analysis

Feedwater for the tower was Boulder city water

The new program utilizes new chemistry that is completely halogen stable and provides performance far superior to that obtained with the industry-standard phosphonate and azole (tolyl triazole)

The significant increase in heat load in cooling water systems in distilleries

products is similar to the order of solubility of the metal hydroxides

and interface with an operational nuclear plant

The ability to efficiently and economically remove suspended solids and nutrients in a single step is realized by using a gravity driven

due to this stream's high salinity

The composite spacers have proven their effectiveness through two years of service

" State-of-the-art retrofit will be discussed

This project represents a progressive and proactive approach to current and future environmental impacts associated with the thermal circulating water system discharge at the power station
