Wastewater Treatment: An Overview!

 With the ephemeral boost in population comes an increase in water consumption and pollution. Therefore, the challenge is to build wastewater treatment technologies that are accessible and efficient so that no polluted water is discharged into the environment.

Firstly, it is essential to know what wastewater is and how you recognize it as waste. It includes water from businesses and homes and runoff from outdoor activities.

This post highlights different steps and methods used to treat wastewater and characteristics taken into account while choosing the right wastewater treatment system.

Read on to learn about the wastewater treatment system:

Importance of Wastewater Treatment

Wastewater consists of different types of pollutants. They are physical, biological, and chemical. It is vital to ensure that water released into the environment is clean and is useful for agricultural purposes like soil irrigation. The objective is to preserve nature while saving energy and costs.

Different Phases of Wastewater Treatment

Step 1: Primary Decantation

Wastewater treatment occurs in several phases. Different method is used at each stage. An individual must be reassured that the first two treatment stages are sufficient for domestic wastewater treatment without using any chemical products. Isn't it good?

The first phase of wastewater clarifier or treatment utilizes a physical approach to remove the impurities from the water, which is termed a physical method.

The primary decantation or physical method is performed in a tank, known as the "Primary Tank." All solids heavier than water by the force of gravity fall to the tank's bottom, and oily materials float to the surface. The pre-treated water passes through a pre-filter that looks like a large brush before releasing in the treatment tank.

Step 2: Secondary Treatment

The second phase comes after the decanting stage and uses the biological method. This biological treatment includes the use of micro-bacteria and involves the use of micro-bacteria. It includes two processes. They are aerobic procedure and fermentation.

Aerobic Process: Bacteria crave the organic waste present in the wastewater and convert then into Carbon-dioxide. Circulation of oxygen is important in the tank.

Fermentation: It requires no air. Water ferments at a certain temperature.

Right Method for Wastewater Treatment

Consider several characteristics to choose the right method for your needs- The bacteria present in the water, wastewater type for treatment, and water destination after its treatment.

Therefore, humans should value the importance of wastewater treatment and choose the method accordingly.
