Listen to episode #178 of the Words on Water podcast to hear CHEMetrics R&D Director Joanne Carpenter and Katie Bell of Brown and Caldwell discuss the rise of peracetic acid and how it has become a disinfection alternative to UV and chlorine at water resource recovery facilities. Thanks to the Water Environment Federation (WEF) for producing…
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…
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 that filming amines can serve as corrosion inhibitors, reduce corrosion product transport, provide smooth heat transfer surfaces, and protect equipment during shutdown or layups. FFAPs…
Turbidity is haze or cloudiness in water caused by suspended matter. Turbid water is commonly described as hazy, milky, cloudy or dirty. High levels of turbidity usually indicate low water quality. A common field test to check for turbidity is to hold a flashlight up to the water sample. If the light makes the…
As water-based industries continue to expand and evolve, the need for water analysis grows with them. New regulations and market dynamics shift the testing needs to lower cost, more precise readings, and faster reporting. Companies look to high-tech advancements like smart meters and on-line analyzers for efficiency and accuracy but continue to rely on proven…
Congratulations to researchers at China’s Dalian Polytechnic University and the School of Environmental Science and Engineering at Shandong University. Utilizing CHEMetrics COD water analysis test kits, they recently determined nanogels may be applied to treat pulp bleaching water in a way that makes current wastewater treatments more efficient and environmentally sustainable. Thanks to…
MIDLAND, VA – The PAA residual analysis method is now available as a Standard Method thanks in part to the work of CHEMetrics Research and Development Director Joanne Carpenter. In collaboration with colleagues from across the wastewater analysis industry and related regulatory agencies, Carpenter led the Standard Methods Joint Task Group to validate a legacy…
Portable DO Test Kits Detect Trace Levels Application Note Many power plants use fossil fuels or nuclear power as sources of heat to boil purified water for the production of steam. The pressurized steam drives turbines to produce electricity. The quality of boiler feedwater must be carefully controlled throughout operations to optimize system performance. Proper…
