Wet oxidation

Wet oxidation is an effective method for treating heavily contaminated wastewater that is not accessible to conventional processes. In addition to classic wet oxidation, there are further developments such as chemical oxidation and UV-assisted wet oxidation, which are tailored to specific requirements and pollutant profiles. These technologies extend the range of applicable

Caustic soda

Caustic soda, also known as sodium hydroxide solution (NaOH), is one of the most important bases in the chemical industry and is widely used in industrial water and wastewater technology. Due to its strong alkaline properties, caustic soda is used for pH control, neutralization, regeneration of ion exchangers and in cleaning processes. At the same time, the handling of

Nominal diameter

The nominal diameter (DN - "Diamètre Nominal") is a standardized parameter for describing the pipe diameter in piping systems. It plays a central role in the planning, design and installation of systems in industrial water and wastewater technology. From the dimensioning of pipes to the selection of fittings and components

Neutralization system

A neutralization system is a technical system for regulating the pH value of industrial wastewater in order to bring it to the legally prescribed pH value for discharge into bodies of water or municipal wastewater treatment plants. Many industrial processes produce acidic or alkaline wastewater which, if left untreated, pollutes the environment as well as pipelines and sewage treatment plants.

Neutralization precipitation

Neutralization precipitation is a key process in industrial wastewater treatment in which pH regulation is used to convert dissolved compounds into insoluble solids. This technique is often used to remove heavy metals, phosphates and other pollutants from wastewater. Neutralization precipitation ensures that metals and other dissolved substances are effectively removed.

Nipple

Nipples are mechanical connecting elements that are used to securely and tightly connect pipes or fittings in industrial water and wastewater technology. As an essential component of complex piping systems, nipples contribute to the functionality and reliability of systems. They are used in a wide range of processes, from drinking water treatment

Nitrate

Nitrate is a chemical compound and an end product in the biological nitrogen cycle that is produced by the oxidation process of ammonium and nitrite in wastewater. Nitrate plays a central role in industrial wastewater treatment, particularly in nitrogen removal, in order to meet the legal requirements for wastewater discharge into bodies of water. Although nitrate

Nitrification

Nitrification is a key biological process in the nitrogen cycle that plays a decisive role in industrial wastewater treatment. In this process, ammonium (NH₄⁺) is oxidized to nitrate (NO₃-) by special bacteria in two stages. This oxidation is particularly important for the removal of nitrogen from wastewater, as ammonium in

Nitrification

Nitrification is a biological process in which ammonium (NH₄⁺) is converted into nitrite (NO₂-) and then into nitrate (NO₃-). This process is a central part of the nitrogen cycle and plays an important role in industrial wastewater treatment in order to break down nitrogen compounds and prevent them from entering water bodies.

Nitrite

Nitrite is a chemical compound and an important intermediate in the nitrogen cycle. In wastewater and water treatment, nitrite plays a central role as an intermediate in the biological conversion of nitrogen. It is formed during the oxidation of ammonium (NH₄⁺) to nitrate (NO₃-) in the nitrification process. At the same time, it is released during the
