Increasing power plant output using a new methodology for cooling loop maintenance
Tom Muilenberg, MIOX director of commercial operations, and Cem Candir, MIOX vice presidents of sales and marketing will present the technical paper, “How Stripping Biofilm From the Cooling Water Loop Impacts Power Plant Production Output” at the Cooling Tower Institute (CTI) Conference in Corpus Christi, Texas, on Feb. 4, 2013.
In the April 2001 issue of Water Quality Products,associates of TCET presented a new method using ozone to treat cooling tower water. Cooling Treatment Systems, Inc. (CTS) of Englewood, Colo., has adapted this method to produce a water treatment system it now is marketing for cooling towers. CTS submitted this new technology to TCET for testing. The results of these tests are presented here.
Testing of the CTS Treatment System Proves Reliable for Cooling Tower Water
The objective of ozone use with cooling towers is to maintain the highest purity of water with the least amount of water waste and chemical use. Chemical use in cooling towers leads to ever-increasing total dissolved solids (TDS), which must be reduced by eliminating water (blow down/bleed off) and then refilling with raw/lower TDS water. This is a vicious circle that will never end unless one of the TDS-increasing culprits (a.k.a. chemicals) is eliminated or reduced.
By explaining some tips and tricks, maybe more water treatment dealers can understand these technologies and use them in their arsenal of treatment methods. Filtration, ozonation, copper ionization and UV light may not be an option on some water supplies or applications, but their usefulness and alternatives to chemical dosing should be considered as an option.
The Diablo Canyon Power Plant at Avila Beach in California utilizes seawater for both cooling water and makeup water for steam generation. Ionics, Inc., Watertown, Mass., designed and built and now operates a complete water treatment system serving the high-purity water needs of this power plant. Over the past eight years, the seawater treatment section has demonstrated excellent long-term performance as a result of strong design, consistent maintenance and qualified operators.
