2nd-year environmental science students joined with Dr. Chamila Pathirana for a field visit to a wastewater treatment facility. Key highlights included primary/secondary treatment processes, biological nutrient removal, and effluent monitoring. Dr. Pathirana demonstrated activated sludge systems, disinfection techniques, and sustainable reuse strategies, linking theory to Sri Lanka’s urban challenges. Students tested water quality parameters and explored innovations like constructed wetlands, gaining practical insights for conservation and land use planning.
