Guide to Chemical Oxygen Demand (COD) Testing

Chemical oxygen demand (COD) is a critical waste treatment measurement in everything from municipal systems to food manufacturing waste streams. Performing COD testing the right way is important in determining wastewater treatment effectiveness and can help diagnose any problems in treatment. In this blog, we’ll cover what chemical oxygen demand is, how to test it, and how…

Chemical Oxygen Demand (COD) in Caustic Wastewater

Testing the wastewater at any manufacturing site is paramount in ensuring the water released into the waste stream meets the required standards. If the quality of effluent water does not meet predetermined standards, hefty fines can be issued by local, state, or federal regulatory agencies. In food manufacturing, large amounts of organic waste are produced.…

Measuring pH of Construction Site Stormwater

Stormwater is a term for the runoff water resulting from a precipitation event such as rainfall in urban areas. Urban areas tend to have large amounts of impervious surfaces, resulting in large volumes of runoff. As stormwater flows over these impervious surfaces, chemicals, pollutants, debris, and sediment are gathered. This pollutant and nutrient-rich stormwater ultimately…
