We’re proud to be exhibiting at this week’s big Aquaculture America 2021, presented by the World Aquaculture Society, in San Antonio from August 11-14, 2021. Swing by the CHEMetrics booth (#316) so we can give you a product demo and show you first-hand how our colorimetric test kits can meet your water analysis needs. See you by…
CHEMetrics is honored to be a part of the debut ‘Stand Ready’ webinar created and hosted by our colleagues at Sentry Equipment. The first topic is one of the most important: Monitoring and control of dissolved oxygen is critical for boiler operators since even low concentrations can be destructive, causing localized corrosion and pitting. Watch…
Significance of Dissolved Oxygen in Aquatic Environments Measuring the concentration of dissolved oxygen (DO) in natural waters is vital in assessing the overall health of aquatic environments. While every ecosystem is different, water bodies need approximately 6 – 10 mg/L (ppm) DO to support aquatic life. Low dissolved oxygen concentration is a strong indicator that…
Welcome to newly renovated CHEMetrics Newsroom! We have reworked this space to make it easier for you to find our latest articles and announcements. Don’t worry, your favorite articles are still here, just organized into new categories that you see on the right. Check back regularly to find the latest news and insightful articles from…
What is DEHA? Dissolved oxygen in boiler system water causes corrosion and pitting of metal surfaces, which can lead to boiler inefficiency, equipment failure, and system downtime. N,N-Diethylhydroxylamine (C2H5)2NOH, or DEHA, is a volatile amine commonly used for oxygen scavenging in a variety of boiler systems. Hydrazine was once in widespread use as a boiler…
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…
