Oxygen Demand: Distinguishing COD and BOD Methods of Analysis

Introduction Oxygen demand measurements are used to estimate water pollution levels entering and leaving wastewater treatment and industrial facilities. Particularly close attention is paid to effluents as high oxygen demand levels indicate a danger to aquatic life. Since treatment facilities are considered point sources, they are regulated under the Clean Water Act (CWA) which in…

Film Forming Amines and their Applications in the Power Plant Industry

Introduction Use of Film Forming Amines (FFA) or Film Forming Amine Product (FFAP) is a growing trend in the power industry for maintenance of boiler systems. Case study literature suggests FFAPs offer protection from corrosion, reduce corrosion product transport, provide smooth heat transfer surfaces, and protect equipment during shutdown or layups. FFAPs can be used…
