The Most Widely Used & Dependable Treatment Methods

Despite the evolution of wastewater technologies, Conventional Activated Sludge (CAS) systems remain one of the most widely used and dependable biological treatment methods in the world. 

At Alveo Water, we design and optimize CAS systems that reflect decades of proven performance—now enhanced by modern control systems and energy-efficient processes to meet the environmental standards.

Originally refined for local conditions in South Africa, CAS continues to offer a cost-effective and robust solution for treating municipal and industrial organic effluents. The process follows a carefully engineered sequence of anaerobic, anoxic, and aerobic zones, allowing for efficient nutrient removal. Final clarification stages then separate treated water from biological solids.
