Overview
This 3-day course introduces the essential principles of wastewater treatment, beginning with the characterization of wastewater and its sources. Participants will gain insight into treatment objectives, regulatory requirements, and the key process units of municipal treatment systems. The course also highlights the role of decentralized treatment technologies and guides learners through the steps of compiling a Wastewater Risk Abatement Plan (W2RAP). Practical application is emphasized through operational guidance, troubleshooting techniques, and case study discussions. Why Should an Individual Attend?
-
Understand the nature and complexity of wastewater, including its sources, constituents, and how they influence treatment design.
-
Navigate key regulations confidently, from national legislation to Green Drop Certification requirements.
-
Gain practical knowledge of treatment units, including both conventional and advanced processes used in municipal systems.
-
Explore decentralized solutions, and how small-scale systems contribute to sanitation access and environmental protection.
-
Learn to compile and apply a Wastewater Risk Abatement Plan (W2RAP) to manage risks and improve system performance.
-
Translate theory into practice, through case studies, troubleshooting exercises, and hands-on operational insights.
