85-13: Advances in Alkaline Cooling Water Treatment Technology: An UpdateOrganic zinc and Chromate zinc programs specifically designed for alkaline pH cooling waters have been developed. The treatment provides excellent corrosion and scale control over a broad range of water chemistries and is applicable to high conductivity and iron contaminated waters. Low levels of zinc are used to reduce the dependency on alkalinity and calcium carbonate super saturation for corrosion control. The precipitation and fouling problems

This paper will present the current challenges in power plant cooling loop treatment and case evidence where biofilm removal improved heat transfer efficiency resulting in increased power plant’s production load

Pollution problems originate

in floe form

in certain situations

particle diameter

Multiple case histories covering the following cooling tower waters are included: 1) Unsoftened surface or well water makeup

This paper presents Vermont Yankee Nuclear Power Station's efforts to prevent water side cooling problems from becoming a limiting factor in maintaining full electrical power output during hot summer months

ranging from desalination to power generation

This design which may be back-fitted to existing natural draft cooling towers reduces the water loading and increases the air flow

droplet size distribution and gas speed

The system design uses conventional techniques in a patented process to achieve 350 concentration cycles of incoming water
