Understanding Nutrient Removal from Wastewater
Every day, millions of gallons of wastewater flow from our homes and industrial facilities into sewers that direct them to treatment plants where the wastewater is treated and converted to effluent that can be safely released into our natural water systems.
Nutrient removal from wastewater involves multiple processes. Nutrients, including nitrogen and phosphorus, facilitate the growth of algae in natural water bodies and can lead to increased levels of toxins, deplete oxygen levels leading to fish kills, and alter the balance of aquatic ecosystems. Let's delve into deeper into nutrient removal from wastewater and discuss the importance of these efforts to the environment.
1. Understanding Nutrient Removal From Wastewater-
There are different methods for nutrient removal from wastewater, with advanced treatment methods being most effective. Some of those advanced methods include absorption filters, sequencing batch reactors, and membrane bioreactors.
These treatment methods have shown to be successful since they eliminate up to 95 percent of the nutrients in wastewater. Absorption filters work in a similar way to activated carbon filters; in this case, the filter material uses microbes for proper nutrient removal from wastewater.
2. The Importance of Nutrient Removal From Wastewater-
Nitrogen and phosphorus are two of the nutrients in wastewater, which contribute to algal bloom, among other negative impacts to the ecosystem. The presence of algae makes water appear cloudy and greenish, blocking sunlight from reaching other aquatic plants and causing oxygen depletion in natural water bodies.
The growth of algae can also cause health hazards to humans by releasing toxins. By removing excess nutrients before wastewater is released to the environment, we can prevent these negative effects and preserve the health of our waterways with the proper treatments for nutrient removal from wastewater.
3. Impact on the Environment-
Without nutrient removal from wastewater before it is discharged into water bodies, aquatic life is adversely affected. Algal blooms can block sunlight from sunlight-dependent aquatic plants, which in return reduces oxygen levels for fish and other aquatic animals. As they die and decay, they accumulate waste, consuming available oxygen in the water to levels that cannot support normal biological activities in aquatic life.
4. Nutrient Removal from Wastewater and our Health-
In an indirect effect, nutrient removal from wastewater has a positive impact on our health. Nutrients, especially nitrogen and phosphorus, contribute to the growth and development of wetland plants that form a natural barrier against erosion and water pollution. Removal of the nutrients from wastewater promotes the growth of these pants, which in return ensures the health and wellbeing of humans.
5. Importance of Proper Wastewater Treatment-
By implementing advanced treatment processes for nutrient removal from wastewater, we can prevent negative impacts on the ecosystem and enhance the health and wellbeing of humans. Proper sewage treatment is a basic right, not just for the environment and the responsible use of the earth's resources but also for the protection of public health.
Nutrient removal from wastewater is an essential part of wastewater treatment. Excessive nutrients in natural water bodies caused by untreated wastewater can affect aquatic life and humans' health. Therefore, it’s crucial that we develop advanced wastewater treatment processes that avoid nutrient disruption in our water systems and protect public health.
Whether you're a developer, homeowner, environmentalist, or city planner, it’s your responsibility to support sustainable wastewater treatment and do your part to reduce the discharge of harmful pollutants into the natural environment.
