What are the 5 Basic Principles of Wastewater Treatment?

Wastewater treatment is a crucial process that is necessary to protect the environment and public health. The five basic principles of wastewater treatment are physical, chemical, biological, tertiary, and disinfection.

Physical Treatment

Physical treatment involves the removal of solid particles from wastewater through physical processes such as screening, sedimentation, and filtration. During the screening process, large solids such as sticks, rags, and plastic are removed from the wastewater using screens. After screening, sedimentation removes smaller particles such as sand and silt by allowing the wastewater to sit in a basin until the particles settle to the bottom. Filtration is then used to remove the remaining small particles from the wastewater.

Chemical Treatment

Chemical treatment involves the use of chemicals to remove contaminants from wastewater. This process involves adding chemicals to the wastewater to coagulate or precipitate impurities so that they can be removed through sedimentation or filtration. Chemical treatment is often used in conjunction with physical treatment to achieve optimal results.

Biological Treatment

Biological treatment is used to remove organic matter from wastewater. This process involves the use of microorganisms such as bacteria, fungi, and algae to break down organic matter into simpler, more stable compounds. This process occurs naturally in rivers and lakes, but in wastewater treatment plants, it is artificially accelerated by controlling the conditions in which the microorganisms grow, such as temperature and pH levels.

Tertiary Treatment

Tertiary treatment is the final stage of the treatment process, where the water is treated to a high standard before being released back into the environment. This process involves the removal of dissolved solids and other contaminants that have not been removed during the previous stages of treatment. Tertiary treatment may include processes such as reverse osmosis, activated carbon adsorption, and membrane filtration.


Disinfection is the final stage of the wastewater treatment process, where any remaining pathogens, bacteria, or viruses are destroyed to ensure that the water is safe for release into the environment. Disinfection methods may include chlorine, ultraviolet radiation, and ozone.

Advantages of the 5 Basic Principles of Wastewater Treatment

Protection of Public Health

Wastewater treatment is essential to protect public health by ensuring that wastewater is treated to a high standard before being released into the environment. Wastewater can contain pathogens, bacteria, and viruses that can be harmful to human health, so effective wastewater treatment is necessary to protect public health.

Protection of the Environment

Wastewater treatment is essential to protect the environment by removing contaminants and pollutants from wastewater before it is released into the environment. Wastewater can contain nutrients, heavy metals, and other pollutants that can be harmful to aquatic life and ecosystems. Effective wastewater treatment can help to protect the environment and promote healthy ecosystems.

Water Conservation

Wastewater treatment can help to conserve water by treating wastewater to a high standard before it is released back into the environment. This treated wastewater can then be reused for non-potable purposes such as irrigation, landscaping, and industrial uses, reducing the demand for freshwater resources.

Energy Conservation

Wastewater treatment can also contribute to energy conservation. For example, anaerobic digestion can be used to treat wastewater, which produces biogas that can be used as a renewable energy source. Additionally, energy-efficient equipment and processes can be used to reduce energy consumption during the treatment process.

Economic Benefits

Effective wastewater treatment can also provide economic benefits. Reusing treated wastewater for non-potable purposes can reduce the demand for freshwater resources, which can result in cost savings for water utilities and industrial users. Additionally, recovering resources such as biogas and nutrients from wastewater can create new revenue streams and reduce operating costs.
