This article discusses the treated parameters in the Sewage treatment plant (STP). It will also discuss the new guidelines by the Government.
A sewage treatment plant is used to treat the sewage that flows from the household and industries to safely dispose of the harmful chemicals to do not harm the environment and human body. Sewage contains both high inorganic and organic materials. The essential work of a sewage treatment plant is to treat and dispose of these materials so that the water can safely be returned to the environment. It is an eco-friendly process.
A sewage treatment plant works in four phases, i.e. preliminary, primary, secondary, and tertiary. These phases have been discussed in brief as follows:
1. Preliminary phase: This phase removes solid waste like plastic bottles, tree branches, wrappers, coarse objects and materials.
2. Primary phase: This phase of primary treatment is done in the sedimentation tanks. In sedimentation tanks, all the organic matter settles at the bottom, and the inorganic matter such as oil and grease is moved to the skimmers for further cleaning. This phase helps in the removal of at least 60% of the waste.
3. Secondary phase: This secondary treatment phase is done to separate the biological floc from the liquid using aerobic biological processes. The water is cleaned up to 90% in the secondary treatment through the use of secondary clarifiers.
4. Tertiary phase: This is the advanced phase of a sewage treatment plant. In this phase, pathogens, nitrogens, phosphorus and other inorganic materials are cleaned by disinfecting the water chemically.
The treated parameters in STP include:
1. pH.
2. Levels of BOD and COD.
3. Suspended solids and quantity of nitrogen and ammonia nitrogen.
