Biological nutrient removal is the process of removing the hazardous contents of wastewaters that are used for fertilization and keeping them out of groundwater supplies. There are several options for the removal of biological nutrients from wastewater, which include chemical, mechanical and anaerobic processing. The following biological nutrient removal steps will help you understand this process and how it can be used for your wastewater treatment needs:
1. The Anaerobic Tank System Needs to Store Wastewaters in Low Oxygen Conditions
The first step in treating wastewater to remove the biological nutrients is to store it in a tank that has lower oxygen and nitrogen gas levels. This is done by pumping the wastewater into a sealed tank, where these conditions will help to promote the growth of bacteria that will later breakdown the biological nutrients in the waste.
2. Natural Bacteria Are Used When the Wastewater Leaves the First Tank to Be Broken Down in The Next Tank in The System
After the conditions in the first tank have promoted the growth of the right bacteria, the wastewater will move to the next step in the process. Here the conditions of the tank will be ideal to help promote further growth of the bacteria that breaks down the biological nutrients, and aeration may be integrated into this step in the waste treatment system to speed up the process.
3. Often, The Bacteria Levels Are Kept at An Ideal Level to Break Down the Biological Nutrients in Waste
Sometimes, the bacteria levels need to be raised artificially by adding agents that help promote their growth. If the levels of bacteria get to low to break down the biological nutrients, they will be raised by treating the wastewater. Usually, this step is not needed if the conditions are kept correctly for all the tanks in the waste treatment system.
4. Once the Biological Nutrient Removal Process Has Finished, The Wastewater Is Safe to Be Spread on Soils
Once the biological nutrient removal process has been completed, the wastewater fluids can then be stored, used for certain irrigation needs or spread over open soils. These soils are free of the hazardous biological nutrients that can contaminate groundwater supplies.
These are some of the facts that you will want to know about biological nutrient removal and how it can be used for your wastewater treatment needs.
