A-Z of Wastewater Treatment & Chlorine Treatment (Hybrid) - Covington, IN

Course Description

This full-day training provides a comprehensive look at both wastewater treatment operations and chlorine disinfection practices used in water and wastewater systems.

The morning session focuses on wastewater treatment plant types, processes, and operational control. Participants will review the key data that should be routinely collected, how to interpret that data, and why it is critical for maintaining compliance and optimizing plant performance. Core process control calculations—including sludge age, Mean Cell Residence Time (MCRT), pounds of solids, Sludge Volume Index (SVI), and Food-to-Microorganism (F/M) ratios—will be covered, along with the importance of trending data to improve efficiency and stability. The session will also address common causes of process upsets, troubleshooting techniques, and corrective actions.

The afternoon session shifts to chlorine disinfection, providing an in-depth overview of how chlorine works to inactivate pathogens in both water and wastewater systems. Participants will explore chlorine chemistry, key operational parameters (such as pH, temperature, and dosage), and how these factors influence disinfection effectiveness. The course will cover various forms of chlorine (gas, hypochlorite, bleach), associated equipment, disinfection by-products, safety considerations, emergency response procedures, and essential dosing calculations.
