Which is best Septic tank or Wastewater Treatment systems?
Now, the answer to this question depends on many factors and varies from person to person.
Some facilities have septic tanks, while others have sewage treatment systems. Basically, both systems have the same functionality. It is to effectively, efficiently and safely remove and dispose of waste from your property.
However, there are some notable differences between them, which are mainly based on how they decompose and dispose of waste.
Let's take a look at some of the differences between septic tanks and wastewater treatment systems to help you decide which system is best for you.
1. Degradation process
The disassembly process used in each system makes the biggest difference between them. In septic tanks, wastewater enters the tank; solids sink to the bottom, and anything that floats rises to form a layer of foam. Between these two layers is a fairly clear body of water containing bacteria and chemicals. Most of the waste is broken down by natural and biological processes.
In Wastewater treatment plant, wastewater is mechanically decomposed using a series of rotating disks designed to activate the decomposition of waste by aerobic bacteria. This process produces harmless wastewater, which can generally be discharged without further treatment.
2. Sewage
With the help of self-forming bacteria, septic tanks break down the disposedsolids. However, this process produces wastewater that is only about 70% clean. That is, it needs to be further processed before being released to the environment.
In the wastewater or sewage system, the aerobic decomposition of solids is much more complex, so the resulting wastewater is 95% clean and can be discharged directly into the environment for infiltration.
3. Servicing
As the septic tank works on the basis of a natural process and utilises the forces of gravity to carry out its function, there is no need for any servicing of the system.
With a wastewater treatment system, the many mechanical components do require regular servicing to keep them in good condition and working effectively.
4. Emptying
As mentioned, a septic tank allows solids to fall to the bottom of the tank while anything that floats will automatically rise to the top. Therefore, after long-term use, the layer of solids at the bottom will increase significantly and the septic tank should be emptied. The frequency with which septic tanks need to be emptied depends on the usage, but usually septic tanks should be emptied at least once a year.
Aerobic decomposition of solids is much faster, so clogging is less of an issue, reducing the need to empty the wastewater treatment system.
5: Disposal
Disposal of wastewater in your property is an important aspect. To get the most out of your system, it is important to understand the differences between the two types of systems before deciding which options to install.
What happens to the waste?
The treated wastewater is not environmentally friendly and will eventually be placed in a collection tank.
Sewage pipelines at sewage treatment plants carry waste to the treatment plants.
Therefore, it is advisable to analyze the requirements along with their strengths and weaknesses before drawing any conclusions.
Conclusion
In India your decision to choose septic tank or municipal wastewater treatment system depends upon the municipality in which you live. Either it has a sewerage system or a septic tank.
As India is progressing towards WASH and looking forward to constructing many STPs, it is safe to say for those areas you need septic tank.
