14-07: Restoration of Concrete Cooling Towers Damaged by Reinforcing Steel GeneralThis paper describes the ongoing restoration of two reinforced concrete hyperbolic cooling towers that exhibited extensive deterioration due to corrosion of the embedded reinforcing steel. The cooling towers were constructed in 1983 and 1985 and are each 453 feet tall reinforced concrete shell structures. The restoration work included the removal and replacement of more than 200,000 square feet of concrete and the installation of an impressed current

brackish makeup and zero discharge

Described are results from a product evaluation that led to the replacement of chlorine gas in 25 cooling towers

an alternative environment friendly & biodegradable Poly diallyl dimethylammonium chloride (DADMAC) studied for pre-treatment of water

This paper discusses characteristics that must be considered when designing a universal direct drive motor

the company has to carry out major renovations of the fills located in the cooling towers

the existing laws governing the discharge of molybdate are reviewed and the future disposition of this material scrutinized
