Dr Anant Kumar HOD Department of Chemistry Bakhtiyarpur College of Engineering Patna SPECIFICATION OF WATER i Boilers Zero hardness Hard water a prevents efficient heat transfer by scale formation . In the biological treatment of wastewaters aeration is essential to raise the dissolved oxygen DO level to allow aerobic bacteria to work and reduce the pollution load BOD of the waste and thus to improve water quality The rate of oxygen transfer in Point Source of Polluted Water in Gargas, France.

Introduction. Bob . McIlvane. and his staff posed a set of questions to me that are very important regarding HRSG water/steam chemistry and prevention of corrosion and fouling in steam generators. Even seemingly minor issues have been known to cause failures that cost power producers millions of dollars, and in some cases even claimed lives. This is the ultimate cost..
