Role & Importance of Sewage Treatment Plant (STP)

Importance of Sewage Treatment Plants:

Over the past few decades, sewage and sewage treatment research and technology have evolved. The population of the world is expanding fast, and people are looking for natural resources in clean water sources such fresh rivers, wells, and groundwater. Natural resources will eventually become scarcer.

This has caused the emphasis to shift from preventing pollution to reducing its effects. Wastewater cannot now be disposed of in land or water bodies without suitable and efficient treatment procedures.

India has the second-largest population in the world and the highest population density in its Gangetic plains as well as other parts of the country. It also boasts 4% of the total fresh water available on Earth. India must therefore work towards sustainable water use, water recovery, and water re-use in order to satisfy the basic need for water for its citizens.

Maintenance of Sewage Treatment Plants:

Utilising reliable and effective machinery is the first rule of thumb for maintaining these plants in good condition for companies or businesses. Aerators and clarifiers are two examples of crucial machinery that are available in a variety of forms and capacities. However, it is advised to use high-quality sewage treatment plant designs because low-quality aerators and clarifiers can lead to issues like insufficient solid sludge deposition and high energy consumption when used in the activated sludge process. Starch wastewater treatment is occasionally a better option for people.

A team of good quality ensures

• Clarifies should not be clogged with solid waste

• There is no biological growth in your aerators

• The growth of the filaments is zero in the aeration tanks

However, no matter how good the equipment is, you need to call periodically to get service and maintenance on this equipment to last a long time.

Working of Sewage Water Treatment Plant:

Although it is very simple, the recycling of treated sewage requires careful attention to detail and maintenance. Here we have explained the working of the plant.

Sedimentation: In the first step, solid waste is sedimented to leave only liquid waste on the surface. Then, with the aid of the clarity procedure or the devices referred to as clarifiers, this liquid stuff is separated from the solid waste. The fundamental idea behind this method is to remove solid trash and only leave liquid waste for the subsequent stage of sewage treatment.

Aeration: Wastewater or Sewage has a very high BOD, that is, a biological demand for oxygen. This demand is met with the help of aerators. The aerators help increase the oxygen content by quickly mixing the waste with the oxygen generated in the aeration tanks. This leads to a rapid treatment of wastewater. Disinfection: Depending on the waste, there are many processes that help in the treatment of wastewater. But generally, the last process in wastewater treatment is disinfection. This process helps disinfect wastewater and eliminate toxicity so that it can be disposed of in local water tanks.

What is the role of STP Plants in controlling water pollution?

The firm hold that sewage treatment plants provide to maintain the ecosystem’s balance helps to reduce water contamination. Despite being straightforward, the sewage treatment process is rarely used. Diverse media channels must be used to spread awareness of sewage treatment.

In less developed countries, a lack of water is a major factor in the slow rate of population increase, and water pollution is bad for people’s health and hygiene. Only a small portion of the world’s water, which makes up three-fourths of its total volume, is suitable for human consumption. Therefore, it is important to encourage the reuse of water in industry and agriculture. Reuse is impossible without efficient sewage treatment; hence sewage treatment plants are just as important as hydropower plants.
