Nutrient Removal in Wastewater Treatment: Why It’s Important and How We Do It

Nutrient pollution is one of the biggest challenges facing water treatment plants today, and results in needing an effective nutrient removal system in place. Nitrogen and phosphorus are two of the most common pollutants found in wastewater. These nutrients can come from a variety of sources, including sewage, animal waste, and fertilizers.


Excess nutrients can lead to eutrophication, which is when a body of water becomes too rich in nutrients. This can cause algae blooms and other problems for aquatic ecosystems. In addition, nutrient pollution can contribute to the formation of harmful bacteria like hypoxia-causing bacteria. This is why nutrient removal is essential for protecting the environment.

The Importance of Nutrient Removal in Wastewater Treatment

Nutrient removal is important in wastewater treatment because it helps to protect our water resources from nutrient pollution. Excess nutrients in the environment can lead to eutrophication; which is a process that can deplete oxygen levels in bodies of water and leads to killing fish and other aquatic life.


Nutrient pollution can also cause Harmful Algal Blooms (HABs), which are large growths of algae that can block sunlight and oxygen from reaching aquatic plants and animals, also leading to their death. Nutrient removal helps to reduce nutrient pollution by removing harmful nutrients from the wastewater before it is discharged into the environment.


The process of nutrient removal is important because it helps to protect our water resources and the plants and animals that depend on them.


How the Nutrient Removal Process Works

The first step in nutrient removal is removing solid waste from the water through a process called primary wastewater treatment. During the primary wastewater treatment process, large pieces of solid waste are removed from the water through screening and settling.


Screening involves using physical barriers to remove large pieces of debris like sticks or leaves. Settling involves allowing smaller pieces of debris to settle at the bottom of a tank where they can be removed. After the primary wastewater treatment process, the water moves on to the secondary wastewater treatment step, where bacteria is used to eat away at the smaller pieces of organic matter that remain in the water.


The secondary wastewater treatment process usually takes place in large aeration tanks where oxygen is bubbled through the water to help the bacteria thrive. Finally, the wastewater moves on to the tertiary wastewater treatment process; which is a more advanced process that for even further nutrient removal.


The most common tertiary wastewater treatment method is called activated sludge, which uses bacteria and chemicals for the nutrient removal of nitrogen and phosphorous. These are the basic steps in understanding the nutrient removal process and the science behind it.


In-Pipe Technology for Nutrient Removal in Wastewater Treatment

The nutrient removal process is vital to keeping our waterways clean and healthy. When we apply the nutrient removal process to wastewater before it's released back into the environment, we can help protect our ecosystems and create healthier places to live for everyone. In-Pipe Technology offers an innovative natural biological solution to the problem of nutrient removal.


Unlike other treatment processes, In-Pipe’s product starts working the moment waste enters the collection system, turning it into an efficient bioreactor that keeps on working until the end stages of wastewater in-plant treatment. If you’re constantly battling nutrient levels at your plant, the In-Pipe nutrient removal method delivers critical headway against regulatory ceilings.


In-Pipe will continually put highly efficient bacteria in your system well before the wastewater comes into the plant. The collection system will reach its full potential as a large biological reactor, which can lead to additional plant efficiencies.


In-Pipe Technology is a cutting-edge solution to the problem of nutrient removal, and it is sure to revolutionize wastewater treatment in the years to come. For more insights like this, or to learn more about nutrient removal, see our other articles here.
