Process control is an important part of wastewater treatment. Operational parameters and design standards normally used for process control and troubleshooting will be discussed, along with how they are used to evaluate and monitor treatment units and processes. Participants will be given worksheets for calculating pounds per day loadings, food to microorganism ratio, sludge age, and mean cell resident time along with several process control examples to complete in class. Participants will be divided into teams to complete at least two process control assignments using the tools and skills taught earlier in the class. Nutrient removal will be discussed, but the focus will be on utilizing operational parameters and design standards for process control. The course will cover flow-through and batch processing activated sludge treatment. This training is to prepare individuals for certification and licensure as well as renewal of licenses and certification in the water and wastewater industry.
