What are a sewage treatment plant and its different methods?

A sewage treatment plant is a facility that provides a systematic approach for treating human excreta and Wastewater. They function by reducing biological oxygen demand, removing any sludge, and preventing the release of disease-causing organisms into the environment.

The STP is a facility where Wastewater and sewage can be processed and treated to reduce water pollution. It also helps in the production of fertilizer and biogas. Sewage treatment plants can work by a variety of methods, including:

• 1. In activated sludge plants, the biological oxidation process is carried out in tanks containing aerated liquid containing microorganisms.
• 2. In trickling filter plants, solids are separated from a liquid via gravity or vacuum, which causes the solids to settle on screens or filtration devices.
• 3. In membrane bioreactors (MBRs), solids are removed via microfiltration or ultra filtration membranes while bacteria decompose organic matter in an aerated liquid phase.

How do sewage treatment plants work? 

Wastewater is any water that has been used or came into contact with raw sewage. The treatment of this Wastewater is what differentiates the different types of sewage treatment plants. The STP working can be bifurcated into three types of wastewater treatment plants. These are described here as below: 

1. Primary treatment: Primary plants treat the Wastewater before it becomes polluted. In this plant, mainly the sludge and all the solid particles get settled at the bottom of the tank. The water so filtered is sent to the following processing unit, i.e., the Secondary plant.

2. Secondary treatment: Secondary plants take the primary treated water and further treat it to remove bacteria and other pollutants. In this process, the water is treated so that all the bacteria, viruses etc., get destroyed. 

3. Tertiary treatment: Tertiary plants are what you would find at a water treatment plant where water comes from a well or natural aquifer instead of from a pipe or river. In this process, the water is further treated with disinfectants to make it better in taste and odor. This is a final staged process in which the water is cleaned before it is recycled and reused. 

What is the primary goal of a sewage treatment plant?

The main goal of a sewage treatment plant is to treat the Wastewater and make it safe for human and environmental contact. Physical processes can either treat the Wastewater like solid-liquid separation or biological functions like aerobic digestion.

A sewage treatment plant needs to meet several requirements, including withstanding environmental factors like weather and earthquake zones. It also needs to have the capacity to treat Wastewater, be energy efficient, and produce a minimal amount of waste.

It is a system that is used to clean and purify Wastewater that is discharged into the environment. The main goal of a sewage treatment plant is to protect the environment from water pollution by removing contaminants such as bacteria, nutrients, chemicals and particulates.

Whether it is from a commercial building or industrial site, wastewater needs to be cleaned before it is discharged. A sewage treatment plant can help with this process.
