The Positive Impact Of Waste Water Treatment On Our Environment

The Positive Impact Of Waste Water Treatment On Our Environment
08 Jun 2022

Although the Earth is covered with 70% water, there is only 1% water that is drinkable. When wastewater is discharged into water bodies it degrades the quality of fresh water for human consumption. Thus, without the assistance of wastewater treatment facilities, the volume of untreated wastewater will devastate the environment and lead to a scarcity of safe drinking water. Nations with water treatment facilities utilise a variety of ways to achieve one common goal: treat as of little water as possible and let it evaporate back into the environment. This is mostly done to keep the human race alive and the world green and prospering.

How Does Waste Water Treatment Help Environment?

One of the biggest reasons behind the growth of wastewater treatment facilities is to aid and revive the marine life that will otherwise extinguish under a layer of chemicals. When the treated water is discharged back to the environment through the process of evaporation, the water vapour forms uncontaminated could that descends upon the Earth. This process prevents the process of acid rain, which is not just harmful to humans but also to crops. Additionally, the treated water also helps reduce the risk of potentially deadly water-borne diseases.

Wastewater Treatment Protects Human Health and Nature:

When dangerous chemicals like phosphates and nitrogen enter water bodies, they encourage plant growth, which releases deadly pollutants into the water. Toxins deplete oxygen levels and create dead zones in bodies of water, causing marine life to choke and perish. Thus, the impact of wastewater is not only confined to human suffrage but also to others. Wastewater treatment facilities purify water by a variety of techniques such as industrial wastewater treatment, carbon filter treatment, pressure sand filter, greywater treatment, sewage water treatment, and others.

Why freshwater bodies are toxin ridden:

Even while nature is endowed with healing capabilities, such properties have limitations. Since the world population has grown in the past few years and continually booming, addressing wastewater issues are quickly becoming a necessity. The following are common causes of natural water treatment overload:

  • Toxic waste and wastewater are discharged into bodies of water by companies and homes.

  • Constant rubbish dumping into rivers and sewer systems

  • Massive cargo ship oil leaks

  • Laundry and animal washing in the river

Correct Method To Discharge Waste Water:

Wastewater treatment plants are meant to filter and sanitise contaminated water to remove pollutants, hazardous chemicals, pathogens, and other germs and bacteria. The remediation of polluted water takes place in phases.

The first stage of industrial water treatment cleans the water of solid particles such as metal, plastic, paper, and other waste items. This procedure is carried out in a sedimentation tank.

In the secondary stage, following that, the partially cleaned water is subjected to a biological process in sedimentation tanks that employs naturally existing microbes to decompose suspended organic contaminants.

The tertiary treatment stage is the third and last stage of water treatment. At this stage, the water is filtered using carbon and sand filters to eliminate biological germs that are detrimental to human health. If the cleaned water is intended for human consumption, the purification procedure might be repeated numerous times depending on the proportion of pollutants. Otherwise, the cleansed water might be used to irrigate crops or discharged into rivers or streams.

Passing through the stages of water treatment the wastewater is purified before releasing it back into the environment. For the sustenance and thriving of human life, wastewater treatment plays a key role in minimizing water pollution and satisfying the growing demand of fresh water.
