How Does a Domestic Sewage Water Treatment Plant Function?

A Sewage water treatment plant can be used in leading industries along with residential properties of the micro-level as well. The plants are put up at urban estates that include only a small number of people and thus known as Domestic Sewage Water Treatment Plant. These plants are positioned to stop water lack in areas or properties presently facing one. Domestic sewage considerably includes the waste in the form of paper, food, wastewater of bathroom and sink, human waste etc. It is mandatory to remove all this waste before allowing the wastewater to move out in the environment. The cleaned water will be fit to reuse. This will enable to develop a feasible and eco-friendly environment and will help to save water for our future generations.

Sewage water treatment plant can eliminate all major contaminations from water irrespective of its solid or tiny state. Hence, the domestic plant follows a process to achieve standard treated water.

1. Sedimentation

This is the primary stage of the water treatment process. In this stage, the water is released in the tanks for some period of time, allowing the solid waste to decompose at the bottom of the tank. This will result in a sludge that can be scraped off or pumped out into a separate facility, to be treated further. The tank will have oils and grease as residue, floating on top of the surface which can be easily removed.

2. Decontaminating from the contaminants

The next stage after sedimentation involves breaking down of the contaminants. This is done by exposing the sludge to oxygen. This is a crucial biological process as it allows the bacteria to break down the contaminants. This may result in remains in solid nature. These can be assorted into two types of systems:

  • • Fixed Film Filtration- It uses a mix of filtrations and collects the remains on a growth medium.
  • • Suspended Growth Systems- It blends the sludge with the microbes so that the waste can be transformed into a solid-state.

3. Enhance the standard of water through Sand Filtration

The third stage evolves refining the quality of water through sand filtration. This achieved through a mix of techniques along with sand filtration. A distinct step in this method lets the aquatic plant grow inside these waters, in order to remove remaining particles and overabundant phosphorus and nitrogen.

4. Disinfection

This is the last stage of a domestic sewage water treatment plant. In this stage, many sterilized substances are added into the water in order to remove the remaining microorganisms. This step uses methods like chlorine light, ozone light, ultraviolet light, making the water ready to be returned into the environment.

Methods of Disinfection:


  • • Chlorine- Despite being the most common method to get implemented extensively, Chlorine poses a threat to our health.
  • • Ultraviolet- It is immensely efficient in killing the bacteria but they might still remain in the water due to the presence of solids.
  • • Ozone- Ozone is the safest option but not many opt for it as it is expensive.

After this step, the sludge will be heated in this stage. This will make the water fit for agricultural purposes by killing the remaining pathogens in the water.

Our wastewater includes different dangerous infectious organisms that cause some serious damage to our eco-system around us will be hazardous to us as well. Remove them all before they pollute the environment near you with a domestic sewage water treatment plant offered by Genex utility.
