Wastewater Treatment

Wastewater Renewal — 24 Contact Hours

Twenty-four hours across the whole treatment train, from headworks through biosolids.

Course overview

Wastewater Renewal — 24 Contact Hours is a 24-contact-hour refresher for working operators who need focused technical training or documented continuing education. It reviews practical knowledge used in collecting, treating, stabilizing, and returning wastewater to the environment while protecting public health and receiving waters, with clear attention to safe work, dependable service, water quality, and regulatory responsibility.

Major study areas include Characterization of wastewater, Wastewater sampling and flow measurement, Preliminary treatment and screening, Grit removal, Primary treatment and clarifiers, Activated sludge fundamentals, Aeration and dissolved oxygen control, Return and waste activated sludge, Secondary clarification, and Trickling filters, followed by additional grade-specific review and application.

The course revisits wastewater characteristics, sampling, preliminary and primary treatment, biological processes, solids handling, disinfection, laboratory control, safety, regulations, and process mathematics at a pace suited to working professionals. Examples and checks reinforce the connection between routine tasks and decisions such as reading process indicators, correcting treatment problems, balancing biological systems, managing solids, and documenting compliant plant performance.

Training is self-paced and available online during the access period. Your classroom records progress, and a completion certificate is generated after the required lessons and checks are complete. Keep that certificate with your personal renewal documentation.

Contact-hour acceptance, topic limits, and renewal periods vary by credential and agency. Confirm that this course fits the certificate and renewal window you currently hold.
