Sewage Treatment Plant
Introduction
A sewage treatment plant is a crucial facility for processing and purifying wastewater.
Site Selection
Careful consideration of location based on factors like population density and environmental impact.
Inflow and Influent Characteristics
Understanding the nature and volume of incoming sewage.
Primary Treatment Stage
Screening to remove large debris and sedimentation for solids separation.
Secondary Biological Treatment
Activated sludge process or trickling filters for organic matter degradation.
Aeration Systems
Providing oxygen for microbial growth and metabolism.
Clarifiers
Settling tanks to separate treated water from sludge.
Tertiary Treatment Options
Filtration, disinfection, and chemical treatment for enhanced purification.
Sludge Management
Thickening, digestion, and dewatering of sludge for disposal or reuse.
Odor Control
