Sewage Cleanup Service: The Process of Sewage Treatment

Wastewater treatment is a multi-step process that involves the removal of contaminants from wastewater. The process is designed to protect public health and the environment. The first step in wastewater treatment is screening, which removes large objects like rags, sticks, and rocks. The wastewater is then passed through a grit chamber, which removes sand and gravel. The wastewater is then pumped to a primary clarifier, which allows the solids to settle out. The settled solids are removed and sent to a landfill. The clarified wastewater is then sent to a secondary clarifier, which removes additional solids. The clarified wastewater is then disinfected and discharged to a receiving water body.

Subtopic: How Clean is Water After Sewage Treatment?

The cleanliness of water after sewage treatment depends on the type of treatment process used. Primary treatment removes about 60% of the contaminants from wastewater. Secondary treatment removes about 90% of the contaminants from wastewater. Tertiary treatment removes about 99% of the contaminants from wastewater. The type of treatment process used is determined by the quality of the receiving water body.

Primary treatment is the most basic type of wastewater treatment. It involves screening, grit removal, and primary clarification. Primary treatment removes about 60% of the contaminants from wastewater. The treated wastewater is then disinfected and discharged to a receiving water body.

Secondary treatment is a more advanced type of wastewater treatment. It involves screening, grit removal, primary clarification, and secondary clarification. Secondary treatment removes about 90% of the contaminants from wastewater. The treated wastewater is then disinfected and discharged to a receiving water body.

Tertiary treatment is the most advanced type of wastewater treatment. It involves screening, grit removal, primary clarification, secondary clarification, and tertiary treatment. Tertiary treatment removes about 99% of the contaminants from wastewater. The treated wastewater is then disinfected and discharged to a receiving water body.
