Wastewater Treatment Design- Training Webinar


The training webinar is presented over 3-days, focused on teaching the principles of designing biological wastewater treatment. The first day covers microbial metabolism and wastewater characterization, followed by topics such as organic matter, nitrogen, phosphorous, and pathogen removal. The webinar also covers various aspects, including aeration and mixing, toxicity, bulking sludge, and final settling. Additionally, attendees will learn about membrane bio-reactors, anaerobic digestion, and biofilm reactors. Process control of these systems will also be discussed during the webinar.

Throughout the event, participants will be presented with case studies to further their understanding. At the end of the webinar, attendees will have the opportunity to test their knowledge and provide feedback on the course.

About The Trainer: Brett Keyser (Pr.PC Water) (PGDip ( ProjMan )

Brett has been passionate about water since starting his first job as a Chemist at Midrand Municipality. Since then his career has always had a connection with water and wastewater; from water laboratory services, management of municipal water and wastewater treatment works, design and installation of industrial effluent treatment plants, instant lawn farming as a means of utilizing wastewater sludge, sales, and supply of water chemicals, facilitation of training workshops, design and installation of irrigation systems, regulatory compliance and managing water and wastewater infrastructure projects.

As a water and wastewater treatment specialist he is always seeking business opportunities at municipalities, water utility companies, engineering consultants, and private business to assess water and wastewater systems, conduct risk assessments of these systems and implement control measures, whether it be infrastructure projects, improved management systems, or training of operational and supervisory staff. By playing a small part, he fulfills his desire to ensure that water and wastewater in South Africa and Africa are managed professionally and sustainably.
