Nitrogen removal processes
Nitrogen removal techniques
Methods used to remove excess nitrogen from wastewater, such as denitrification, nitrification, and biological nitrogen removal.
Non-flushable items
Items that should not be flushed down the toilet, such as wipes, feminine hygiene products, and paper towels, as they can cause clogs and other problems in septic systems.
Non-point source pollution
Pollution that comes from diffuse sources, such as runoff from agricultural fields or urban areas, rather than from a single point source.
Non-potable water source
Water that is not suitable for drinking, but can be used for other purposes, such as irrigation or flushing toilets.
Nutrient leaching
The process by which excess nutrients, such as nitrogen and phosphorus, move through soil and into groundwater or surface water.
Nutrient management practices
Nutrient overload
The condition in which water bodies receive an excessive amount of nutrients, leading to harmful algal blooms and other negative impacts on aquatic ecosystems.
Nutrient pollution
The presence of excess nutrients, such as nitrogen and phosphorus, in water bodies that can cause harmful algal blooms and other negative impacts on aquatic ecosystems.
