Description
Water and wastewater treatment are essential for maintaining environmental health and sustainable industrial operations. This course explores the chemical and biological processes used to remove contaminants from water and wastewater, which are crucial for preserving natural water bodies and supporting industrial activities. Understanding these processes is vital for environmental engineering, industrial operations, and municipal planning, as effective treatment protects ecosystems, enhances public health, and ensures regulatory compliance.

This course will teach the principles behind various treatment processes, including coagulation and flocculation, oxidation-reduction, chemical precipitation and suspended and attached-growth biological processes. You will explore technologies such as water softening, ion exchange, activated sludge, trickling filters, rotating biological contactors, moving-bed biofilm reactors and lagoons.  The insights into the design and operational aspects of these processes will enhance your ability to apply them in real-world scenarios, ensuring efficient and effective treatment solutions.

Additionally, you will analyze case studies to observe practical implementations and outcomes, enriching your knowledge and problem-solving skills. This course equips you with the knowledge and practical skills needed to undertake water and wastewater treatment challenges effectively, significantly impacting both environmental and industrial fronts.

Who Should Attend
This course is designed for environmental engineers, consulting engineers, environmental educators, and industrial staff looking to enhance their water and wastewater treatment expertise.

Technicians, technologists, municipal planners, plant managers, and operating personnel will also find this course invaluable for deepening their knowledge and practical skills in managing and improving treatment operations.

Government regulators, environmental consultants, researchers, and students pursuing studies in environmental science or engineering will benefit greatly from the insights and practical knowledge offered in this course.
