Nitrogen in wastewater is a common challenge in both industrial and municipal operations. It occurs in various forms, such as total nitrogen (N-tot), nitrate, and nitrite, and can arise from a wide range of sources, including food production, chemical processes, and leachate.
Elevated nitrogen levels can contribute to eutrophication in lakes and coastal waters. This negatively impacts ecosystems and can lead to oxygen depletion. Therefore, nitrogen emissions are regulated through permit conditions and limit values set by municipalities and regulatory authorities.
With INWATECH’s nitrogen reduction solutions, you get safe and effective technology tailored to your operations and requirements.

Nitrogen in the form of ammonium, nitrate, and nitrite affects how biological treatment works in practice. At high or fluctuating concentrations, the process can become unstable, particularly during the nitrification and denitrification stages.
Rapid changes in load can prevent bacterial cultures from adapting in time. This can result in inconsistent readings, reduced treatment efficiency, and, in some cases, the need for emergency operational adjustments.
Nitrogen is often present alongside suspended solids, which can affect the efficiency of biological treatment and how the process should be designed. To maintain a stable and reliable facility, technology is needed that can handle variations in both flow and water profile.
INWATECH tailors solutions to reduce total nitrogen, nitrate, and nitrite based on your specific conditions. The technology is designed according to water flow, load, and current regulatory limits.
The systems can be installed as standalone water treatment plants or integrated into existing systems. We provide support from the preliminary study and analysis through to the final solution, whether your needs are for a mobile or stationary system. The process is always tailored to your business and your environmental requirements.
In addition to the technical challenges, nitrogen is subject to clear environmental requirements. Total nitrogen (N-tot) is often regulated in permits and monitoring programs because high emissions contribute to eutrophication in lakes and coastal waters.
The Swedish Agency for Marine and Water Management explains how nitrogen affects aquatic environments and why reducing emissions is a priority in Sweden.
For many businesses, it is therefore crucial to ensure that total nitrogen levels remain within established limits before the water is discharged into a receiving body of water or the municipal sewer system.
INWATECH’s nitrogen removal technology is designed for facilities where wastewater or process water contains high levels of ammonium and other nitrogen compounds. These solutions are particularly relevant for:
The systems are designed based on flow rate, load, and applicable emission standards. The goal is a stable and reliable nitrogen removal process that meets regulatory requirements even under varying conditions.
