Two large natural gas-fired, combined-cycle power plants, 800 and 500 megawatts respectively, using recycled water with high ammonia contents for cooling water make-up adopted a new economical stabilized halogen technology to solve bio-treatment problems. The new treatment method resolved biological fouling issues and eliminated the need for shot feeds of a tanker truck load of bleach (~5000 gallons) every one to two weeks and the need for normal continuous dosing of chlorine and sodium bromide. The alternative approach reduced treatment costs by 30%.
