Moreover, due to the harmful toxins present, some of this waste can be so harmful that if left untreated, it can contaminate land and water and spread multiple malignant diseases. That being said, most industries find it extremely difficult to treat sewage water as it is not an easy feat to remove chemical and biological contaminants from liquid wastes.

However, if companies ignore treating the sewage water before dumping it, it could lead to the organization facing multiple fines and lawsuits and pose a potential threat to public health. In this article, we will cover the most common type of pollutants that contaminate wastewater and how industries and efficiently treat the waste before dumping it.

Types of Pollutants Commonly Found in Sewage Water
Biochemical Oxygen Demand

High levels of biochemical oxygen demand, commonly known as BOD, indicate that there is an elevated amount of biodegradable material present in the sewage water, which can cause the presence of harmful pollutants like fecal waste or fertilizer runoff. Industrial or domestic organic waste can also result in high levels of BOD. If wastewater with a high level of BOD is disposed of in a water body, it could lead to depletion of oxygen, which is needed for the survival of aquatic organisms. Hence, it could lead to algal blooms, the death of fishes, and threatening changes in the marine ecosystems.
Nitrates & Phosphates

A high volume of nitrates and phosphates can result in an increase of BOD, weed growth, algae, and phytoplankton if the wastewater is released in a water body. Moreover, this can also lead to eutrophication and reduction of the oxygen levels in the water, which will lead to the extinction of various organisms in the water and eventually hypoxia or environmental dead zones.
Pathogens

The term pathogens are commonly used for bacteria, viruses, fungi, and any other organisms that, when present in wastewater can lead to various types of health issues like cholera, dysentery, salmonellosis, hepatitis A, botulism, severe digestive problems, or even death.

Why Companies Need A Sewage Treatment Plant

As mentioned above, untreated sewage water can lead to multiple catastrophes if released into the environment. Hence, here are some of the most prominent reasons why companies should consider using a sewage water treatment plant:
Fisheries

It is crucial for plants and animals living in water bodies to receive clean water. If freshwater is not provided, it could lead to a mass extinction of living organisms in these waters. Not only does this severely hamper the aquatic ecosystem, but it can also have negative impacts on the fishing industry, sport fishing enthusiasts, and future generations.
Wildlife Habitats

As multiple rivers and ocean water flow through forests and beaches, the lives living on the shoreline and marshes are dependent on these waters. Hence, if the water is polluted, it can directly lead to the death of wildlife habitats living near the water bodies, including waterbirds that use the area for resting and feeding.
Recycle & Reuse

With a shortage of clean water all over the globe, treating wastewater to reuse and recycle is more critical than ever before. Moreover, in addition to helping the environment, this technique can help your factory save on connection fees that can be extremely high due to water shortages.


These are just a few reasons why companies must partner with a sewage treatment plant for cleansing their waste. Companies like Thermax provide excellent options that can be customized based on the need of the factory.
