Why do wastewater operators need knowledge of chemistry?

Understanding chemistry is crucial for wastewater operators because it enables them to grasp the chemical processes involved in treating wastewater. This knowledge helps operators manage chemical dosing accurately, which is essential for a number of treatment processes such as coagulation, disinfection, and nutrient removal. For example, knowing how various chemicals interact with wastewater contaminants allows operators to optimize treatment efficiency, ensure compliance with environmental regulations, and ultimately protect public health and the environment.

Chemistry knowledge also assists operators in monitoring and analyzing water quality by understanding the significance of pH, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and other parameters. Being adept in chemistry supports effective troubleshooting and adjustments to treatment processes based on real-time data, enabling the plant to operate smoothly and efficiently.
