The stage in which the biological processes is used to purify water in a waste-water treatment plants is called secondary sewage treatment

Answer 1

Answer:

The stage in which the biological processes is used to purify water in a waste-water treatment plants is called secondary sewage treatment.

Explanation:

Physical phase separation and a biological procedure are both used in the waste water management technique known as secondary treatment. The stage in which the biological processes is used to purify water in a waste-water treatment plants.

Organic matter is eliminated using biological processes:

• The removal of biodegradable organic matter (in solution or suspension) from sewage or other similar types of wastewater is known as secondary treatment.
• In a sewage treatment plant, the goal is to reach a level of effluent quality that is appropriate for the intended disposal or reuse option.

• As an illustration, bacteria and protozoa eat biodegradable soluble organic pollutants. Solids are removed from wastewater in the primary stage by allowing them to settle.
• The secondary stage further cleans wastewater using biological procedures. These steps are occasionally combined into a single procedure.

Answer 2

The secondary stage further cleans wastewater using biological procedures.

About Wastewater treatment:

• A technique called wastewater treatment is used to clean up impurities from wastewater and turn it into an effluent that can be reintroduced to the water cycle.
• The wastewater is reused or has an acceptable impact on the environment after it is added back into the water cycle (called water reclamation).
• A wastewater treatment facility is where the treatment takes place.
• At the right sort of wastewater treatment plant, a variety of wastewater types are treated.
• Sewage treatment plants are those that handle household wastewater.
• Either a separate industrial wastewater treatment facility or a sewage treatment plant is used to treat industrial wastewater.

What are the three processes in the treatment of wastewater?

• Primary, secondary, and tertiary are the three phases of wastewater treatment.
• Each step improves the quality of water purification. Some applications just require one or two phases.
• Depending on how the water will be used and the ecosystem it will be released into, different levels of treatment may be required.
