The Basics of Sewage Treatment 1- Background: sewage and pollution - Definition of sewage; - Main characterization variables: - pH, temperature, COD, BOD, nitrogen series, phosphorus, solids series; - Main impacts caused: - Decrease in the concentration of dissolved oxygen in the water; - Eutrophication; - Siltation; - Transmission of diseases. 2- Sewage Treatment Plant - Sewage treatment levels; - Types of treatment: - Biological: - Aerobic; - Anaerobic; 3- Main biological treatment processes - Activated sludge; - Aerated biological filter; - Mechanically aerated lagoon; - Stabilization lagoons; - Anaerobic filters; - UASB. The Basics of Water Treatment 1- Contextualization: Water in Nature - Hydrological cycle and water availability; - Main characterization variables: - pH, temperature, turbidity, hardness, alkalinity, color, solids, - Water quality; - Pollution; - Eutrophication; - Legal aspects: Ordinance 888 2- Water treatment plant - Definition of drinking water; - Types of sources: - Surface; - Underground; - Treatment processes: - Conceptualization of coagulation and flocculation; - Sedimentation; - Filtration; - Disinfection. The Basics of ETE Sludge Management and Treatment 1- Contextualization – ETE Sludge: - Characterization of a residue considering NBR 10.004, from the Brazilian Association of Technical Standards (ABNT). - Waste generated in a WWTP: - Preliminary treatment; - Primary sludge; - Secondary sludge; - Need for treatment: - Sludge characteristics; - Transportation and disposal; - Stages of WWTP sludge treatment: - Thickening; - Digestion: - Aerobic; - Anaerobic; - Dehydration: - Natural; - Mechanized; - Disposal.
