What Is Sewage Treatment Plant and Why Sewage Treatment Is a Must?

Sewage is a term used to describe wastewater, often from residential, commercial, and industrial sources. It typically includes water used for various purposes, such as toilets, showers, sinks, and industrial processes. Sewage contains a mixture of water, organic and inorganic materials, and various contaminants. It requires treatment to remove impurities before it can be safely discharged into the environment or reused.

What is sewage treatment plant?

Sewage treatment plants are responsible for the treatment and refinement of sewage and wastewater, transforming it into a more environmentally friendly 'effluent' that can be safely reintroduced into the natural environment. These facilities are vital for maintaining the balance of groundwater, curbing the spread of diseases, and preventing environmental degradation and pollution.

In residential areas, the treated water can be utilized for non-potable purposes such as gardening, vehicle cleaning, construction, irrigation, and toilet flushing. Cleaner water would minimize fatalities due to waterborne diseases, there’d be less negative environmental impact from water pollution and from a much narrower point of view, no house would have to pay for water tankers, because there’d be abundance of ground water on macro scales and reusable water at community levels.

Why sewage treatment is a must?

Sewage Treatment is very essential for cleaner and more hygienic environments. It involves the elimination of contaminants from municipal waste, which includes household sewage and industrial wastewater, thus improving overall sanitation.

This a known fact that industries play a big role in adding to the waste produced every day. The waste generated by factories and industries has detrimental effects on the environment. It results in various illnesses and leads to the pollution of both land and water. Eliminating chemical and biological impurities from the waste using common household or industrial techniques is a challenging task. Hence, sewage treatment is required.

The effects of sewage pollutants

As previously said, pollutants can be found in sewage and can have harmful effects on ecosystems and human health:

1. Decaying organic matter and debris can use up the oxygen in water, leaving no chance of survival for aquatic life.

2. Excessive nutrients, such as phosphorus and nitrogen, can create a toxic environment for aquatic organisms: dramatic growth of plant life such as algae, reduced available oxygen, altered spawning grounds, etc., which can ultimately lead to a decline in certain species;

3. Chlorine compounds and inorganic chloramines can be toxic to aquatic invertebrates, algae and fish.

4. Disease-causing bacteria can pollute beaches and waters, leading to restrictions on drinking water consumption and shellfish consumption.

5. Metals, such as mercury, lead, cadmium, chromium and arsenic, can have acute and chronic toxic effects on species.

6. Other substances such as pharmaceuticals, cleaning and personal hygiene products such as cleaning wipes may also jeopardise human health and wildlife.

The stages of water treatment

Several processes are at your disposal for implementing the various preparation stages of water treatment:

1. Physical processes for mechanical preparation such as aeration, sedimentation or thermal influence. This also includes the use of screens, filters and sieves.

2. Biological processes such as anaerobic wastewater treatment, biochemical oxidation or sludge digestion

3. Chemical processes such as neutralisation, disinfection, flocculation and precipitation

4. Membrane processes such as filtration, osmosis and nanofiltration

The highest volume of wastewater to be treated is in municipal wastewater treatment plants, which is why a more diverse combination and more effective procedure is necessary here. The procedures used depend on the type of wastewater treatment plant.

Why Sewage Treatment Plants Are Essential for PG

Sewage treatment plants are indispensable for PG accommodations, serving multifaceted purposes that enhance the overall living experience. Firstly, they are instrumental in upholding hygiene and health standards within the living spaces. The efficient treatment of sewage ensures that wastewater is free from harmful contaminants, mitigating the risk of waterborne diseases and fostering a safe and clean environment for residents.

Beyond the immediate benefits for residents, sewage treatment plants in PGs contribute significantly to environmental conservation. By treating sewage before disposal, these plants play a pivotal role in preventing pollution and safeguarding local ecosystems. Untreated sewage can have detrimental effects on soil and water quality, making sewage treatment an essential component of responsible waste management in PG facilities.
