A New Award-Winning Bio-Control Approach Cleans Cooling Tower of Biofouling at a Fraction of the Cost of Bulk Hypochlorite
MIOX Corporation, the technology leader in on-site chemical generation, announced recently that a unique bio-control approach developed by exclusive distributor New Technology Systems, Inc. (NTS) has not only achieved significant savings compared to bulk hypochlorite usage, but also increased the production output by more than 7%, or 40 MW at one of Puerto Rico’s main suppliers of energy, the 590 MW Palo Seco Power Plant. Since the 2010 installation of a MIOX system, the Plant has experienced significant improvements in water quality and energy efficiency resulting in dramatic savings in water, chemical and energy usage.
In 2010, the Puerto Rico Electric Power Authority (PREPA) encountered a biofouling emergency at the Palo Seco Power Plant. The heat exchangers were plugged and temperatures rose well above manufacturer specification due to serious biofouling in the plant’s cooling tower system. Through collaboration with NTS, PREPA decided to seek an effective, less costly, greener and safer solution for cooling water disinfection. This led them to change their cooling water disinfection from bulk hypochlorite to using MIOX Mixed Oxidant Solution chemistry.
“Once MIOX was introduced into the system, results were seen immediately and the energy load of the plant increased,” said Carlos Eli Torres, Senior Chemist at Palo Seco Power Plant. “The efficiencies gained from increased load production, reduced chemical and water usage, and lower operations and maintenance costs added up to over $34 million per year in savings. The operation cost of the MIOX unit was roughly a quarter of the bulk hypochlorite price. The switch to MIOX was a no brainer.”
“Not only the cost advantage, but also the effectiveness of the MIOX unit was quite visible and it was another testament of how effective the Mixed Oxidant Solution was removing biofilm,” said Tom Muilenberg, MIOX Director of Commercial Operations. ”Cleaner condenser tubing resulted in increased heat transfer, allowing them to operate their turbines at a higher load at a fraction of bulk Hypochlorite cost.”
Palo Seco Power Plant was awarded the “Innovative Project of the Year,” recognizing the project for successes in Water Conservation and Energy Conservation by The 2012 Environmental Congress sponsored by the Puerto Rico Manufacturers Association. MIOX is now treating all of the 9 PREPA power plants summing up to approximately 5,200 megawatts of output.
