Sewage Treatment Plant- What Is It And How It Works?

A sewage treatment plant works by circulating air to boost the progress of bacteria to degrade sewage. The Doctor Fresh STP plant ultimate goal is to make a cleaner and friendly effluent that involves a similar process to a septic tank but has few differences. A sewage treatment plant can treat commercial and domestic waste as its quantity depends on the size of the plant.

The sewage treatment plant includes physical, biological, and chemical processes to eradicate pollutants. It aims to produce safe sewage water as effluent, and solid waste as sludge or biosolids that can be easily disposed of or able to reuse. The reuse is only applicable for agricultural practices or sometimes used as a fuel source. So, there is no water wastage if you have a water treatment plant and it is suitable for the bulk amount of water.

The Stages Involved In A Sewage Treatment?

The basic construction of a sewage treatment plant is like a septic tank where sewage runs from the primary tank and turns towards the first chamber of the sewage treatment plant. The oil, grease, and scum have been separated to the top of the tank and solid particles are settled on the bottom of the tank. Once the process begins, the sewage travels into the further chamber where sewage is treated for the further pollutants.

This chamber is attached to an air pump that circulates air all over the chamber to elevate the growth of aerobic bacteria. The bacteria break down the contaminants present in the water and make it free from all sorts of physical, chemical, and bacterial presence. The last stage of a sewage treatment plant is done in the settlement tank where solids that accumulated in the bottom remain to sink and the effluent is discharged to soak away.

As the treatment process is over and the wastewater has turned safe for use, it can be flushed into the environment. This is another key area where sewage treatment plants can discharge your effluent into natural water bodies straight from the sewage treatment plant.

The Need Of Sewage Treatment Plant And Its Application

When you are planning for a new sewage treatment plant to turn the wastewater into potable water then it proves the most cost-effective and reliable way of dealing with your wastewater. However, the distance from the sewer can make it impossible to treat wastewater directly from the mains sewer. As the sewage treatment plants come in and can operate from anywhere in case of uninterrupted electrical connection.

The main purpose of a sewage treatment plant is to treat the wastewater and make it usable for various purposes. The sewage treatment plant can deal with more waste than a septic tank and completes the process within the lowest time. During the treatment, the sludge can also build up inside the system, so it is necessary to clean the water treatment plant regularly. In case of under service, the plant can lower its performance and be unable to treat wastewater as earlier.

Here Are The Advantages Of Using A Sewage Treatment Plant

  • The sewage treatment plants are reliable and can encounter fewer problems in lower maintenance
  • It can be installed on any challenging sites where there is the secure power supply
  • The wastewater treatment plant lowers the chances of getting diseased as it cuts the harmful microbes present in the water. It filters out the contaminants before the wastewater leaves the tank and prevents spreading diseases
  • The wastewater treatment plant can work continuously for more than a decade in case of proper maintenance. It proves a cost-effective way to treat wastewater and eliminate all unwanted bacteria in a single treatment
  • The wastewater treatment plant consumes less power than any other treatment plant and makes it cost-effective and environment-friendly
  • The new age wastewater treatment plants need low maintenance because of their self-cleaning technology. Only a scheduled checkup is required once in 2-3 years and can be restored in case of any hassle
  • The modern ear wastewater treatment plants can break sludge faster and find less blockage as it effectively breaks the solids. It also needs low desludging that's why it contaminates less of the ground

Wastewater undergoes primary, secondary, and tertiary treatment processes in the sewage treatment plant. In the first step, large solids are removed from the wastewater, and in the second stage, the biological activities take place, which converts organic matter into stable forms. In the final stage, called tertiary treatment, the disinfection process occurs using UV radiation or chlorination and finally brings the contamination-free water.

The 3 main types of sewage treatment plants are

  1. Activated Sludge Plant (ASP)
  2. Submerged Aerated Filter (SAF)
  3. Suspended Media Filter (SMF)

The 4 main stages of sewage treatment are

  • Primary Sewage Treatment
  • Secondary Sewage Treatment
  • Tertiary Sewage Treatment
  • Sledge digestion

These sewage treatment process deals in part per million to part per billion level of contamination and often involve oxidation. These stages deal with the different kinds of contamination present in the water.

A sewage treatment plant is of various types, which are

  • Tricking filter
  • Non-electric filter
  • Suspended Media Filter (SMF)
  • Submerged Aerated Filter (SAF)
  • Rotating Disk System
  • Sequencing Branch Reactor (SBR)
  • Activated Sludge Plant (ASP)

Various types of sewage treatment plants are available in the Indian market, and all of them have their significance depending upon your needs. So contact the Doctor Fresh team and get the appropriate sewage treatment plant (STP) for yourself.
