Details: Idaho wastewater operators and other water professionals are invited to attend. Each class in this series will provide current operational staff with complete knowledge of wastewater fundamentals. This class can help prep for the wastewater treatment examinations. The online wastewater school provides operators with a review of the current practice for each topic in wastewater treatment. This class reviews wastewater characteristics and composition. We will define BOD, COD, TOC, solids, alkalinity, hardness, pH, and nitrogen and phosphorus species and explore what these terms mean. Domestic wastewater is fairly consistent in composition from the treatment plant to the treatment plant. Unless there are large industrial contributions, domestic wastewater can be expected to adhere to some basic principles. For example, influent BOD should be between 80 and 120% of the influent TSS. Influent TKN should be around 10 or 20 percent of the influent BOD. We’ll look at why these ratios hold true and how they can be used to determine if laboratory data is internally consistent. Knowing typical wastewater characteristics can be extraordinarily helpful in deciding whether sample results are representative. Look at your lab data in a whole new light!
