Study Notes
Introduction to Environmental Engineering
- Environmental engineering applies science and engineering principles to mitigate adverse human impacts on the environment.
- Key differences exist between environmental science—which studies environmental processes and sets standards—and environmental engineering, which focuses on practical design and control systems.
Environmental Science
- Involves the study of interactions between water, air, soil, and organisms to ensure a clean, healthy environment.
- Quantitative environmental science employs mathematical theories to analyze environmental relationships.
Environmental Pollution
- Defined as contamination of the environment by harmful substances.
- Pollution resolution includes identifying adverse effects, determining pollutant sources, and controlling emissions to safe levels.
Environmental Engineering Approach
- Focused on problem-solving, it encompasses remediation, effluent treatment, pollution prevention, and sustainability for future generations.
- Involves social, political, economic, and legal considerations.
Environmental Systems Overview
- Major environmental systems include:
- Atmosphere (air)
- Biosphere (living organisms)
- Hydrosphere (water)
- Cryosphere (ice)
- Pedosphere (soil)
- Lithosphere (rock)
Pollution Management Systems
- Water Resource Management: Includes water supply and wastewater disposal subsystems.
- Air Resource Management: Focuses on air quality management to prevent deterioration.
- Solid Waste Management: Encompasses handling and disposal of solid waste.
Ecology
- The study of organism distribution, abundance, and their interactions with the environment.
- Not synonymous with environment or environmental science but relates closely to physiology, evolution, and behavior.
Ecosystem
- Comprises living organisms interacting with nonliving components, forming an intricate system.
Pollution Classification
- By Medium: Air, water, and soil pollution.
-
By Source:
- Anthropic pollution: Caused by human activities.
- Natural pollution: Occurs from natural sources.
-
By Location:
- Point source: Emissions from specific locations (e.g., factories).
- Non-point source: Diffused emissions from various sources.
-
By Chemical Transformations:
- Primary pollutants: Directly emitted.
- Secondary pollutants: Result from transformations of primary pollutants.
