How Does Effluent Treatment Plant Work?

Water, after all, is an unavoidable aspect of our lives. It is that essential element that is important in our day-to-day life.  Without it, our very existence will be jeopardized.  Polluted water can be very much harmful not only to the environment but also to human health.

Process of Effluent Water Treatment Plant

Water treatment is extremely essential in order to ensure cleaner and safer water. In this article, you shall know about the process of the Effluent Treatment Plant.

The process of effluent water treatment plants is a bit complex. Let us know what the process is:

Preliminary Treatment

The goal of this step is to physically separate big pollutants and solid materials. Fabric, paper, polymers, and wood planks, for example. This level/process includes the following:

Screening

The first unit activity in a wastewater treatment plant is screening. The objective of a screen is to remove big floating solids by having regular apertures.  It removes the big solids from water for collecting the required amount of water easily.

Sedimentation

In this process, water moves slowly, forcing heavy particles to settle to the bottom. The particles that are settled at the bottom of a container are referred to as sludge. This helps to provide cleaner water as the contaminants or dust particles settle at the bottom of the container.

Clarifiers

Clarifiers are tanks with mechanical mechanisms for continuously removing sediments that have been accumulated due to sedimentation before biological treatment.

Primary Treatment

Its main goal is to remove floating and settleable elements such as scattered solids, organic and inorganic compounds from the water. Physical and chemical procedures are used in this treatment. It contains the following items:

Coagulation

Coagulation is a process that involves mixing untreated water with liquid aluminum sulfate. After mixing, small dirt particles cling together as a result of this. This assemblage of particles combines to form larger, relatively high numbers of particles that are easily removed via settling and filtration.

Flocculation

Flocculation is a process that does not result in the neutralization of charge. It entails aggregating destabilized particles into big aggregates so that they may be easily removed from the water.

 pH Control

The pH of the effluent should be between 5.5 and 9.0. To change the pH of wastewater, pH neutralization is utilized.

Acidic waste (low pH): Bases are used to change the pH of a solution. Acids are used to change the pH of a solution in the event of alkali waste (high pH).

Primary Clarifiers

It is used to restrict the flow of water to the point where organic materials sink to the bottom of the tank, and they also contain equipment for removing drifting solids and lubricates from the surface.

Secondary or Biological Treatment:

The goal of this treatment is to remove suspended particles and leftover organic pollutants from the effluent from the first treatment. Biological and chemical mechanisms are involved in this stage.

Aerated Lagoons

It is a treatment pond with artificial aeration to promote wastewater biological oxidation.

Activated Sludge Process

The Activated Sludge Process uses air and a biological liquid droplet made up of bacteria to clean industrial wastewater. It ensures germ-free water.

Trickling Filters

Also known as sprinkling filters, trickling filters are extensively used for the biological treatment of home sewage and industrial wastewater.

Tertiary treatment

The purpose of tertiary treatment is to provide a final treatment stage to raise the effluent quality to the desired level before it is reused, recycled, or discharged to the environment.

Equalization

The main objective of the equalization tank is to equalize the raw effluent from various processing units. The wastewater is deposited in a mixed effluent tank and sent to an aeration tank that also serves as an equalization tank. The effluent is homogenized in the floating aerator before being pumped to the neutralization tank for further treatment.

Disinfection

Water is disinfected before entering the distribution system. Water is disinfected and decontaminated with chlorine. This process ensures germ-free and pure water and also ensures the good health of the people.

Filtration

Filtration is the technique of removing particles from water by passing them through a filter. The filters are built up of layers of sand and gravel. It is a very important technique in order to ensure cleaner water. Cleaning these filters on a regular basis necessitates water application.

Importance of an Effluent Treatment Plant

Effluent Treatment Plant ensures that toxic and contaminated industrial water is treated and made reusable before being released back into the environment. People will be unable to acquire clean, usable water for household or other purposes without this treatment. This treatment lets people use water which is germ free, clean and safe.

It is necessary for ensuring a healthier environment and good health for the people. This helps to get rid of harmful chemicals and potential diseases. It helps to protect the ecological balance of the environment by disposing wastewater used in the industries or factories by making them pollutant free making it less prone to any sort of harmful diseases.
