Study Notes
Oxidation Ponds and Aerated Lagoons
- Natural systems for treating wastewater.
- Minimize infrastructure needs.
Treatment and Disposal of Sludge
- Digestion of sludge involves biological breakdown of solid waste.
- Disposal methods include safe reuse or proper disposal.
Septic Tanks
- Septic systems are used for wastewater treatment in areas lacking centralized sewer systems.
- Design considerations include tank size and leach field capacity.
Disposal of Septic Tank Effluent
- Effluent can be disposed of on land or into streams.
- Methods include soil absorption and discharge to surface waters.
- Regulations govern effluent disposal to protect water resources.
Effluent Standards
- Standards regulate the quality of wastewater discharged into sewers, land, or streams.
- Standards vary based on receiving water body and intended use.
MINAS
- Management of Industrial Waste and Standards (MINAS) regulates industrial wastewater management.
- Enforces regulations on industrial discharge to protect the environment.
Self-Purification Capacity of Streams
- Natural processes in streams can improve water quality.
- These processes include dilution, oxidation, and biological degradation.
