Nitrogen reduction refers to the targeted removal of nitrogen-containing compounds from water or wastewater in order to avoid environmental damage such as eutrophication and to comply with legal requirements. The reduction of nitrogen compounds, in particular ammonium, nitrite, nitrate and organic nitrogen, is of central importance in industrial and municipal wastewater treatment. Nitrogen compounds and their environmental impact Ammonium
Sulphide precipitation is a specialized process in industrial wastewater treatment in which dissolved heavy metal ions are converted into insoluble metal sulphides by adding sulphides. This technique is particularly efficient for the removal of toxic metals such as copper, zinc, lead or cadmium, as metal sulphides have a very low solubility and can be removed by the addition of sulphides.
Sweet whey is a by-product of cheese production that is produced during the rennet coagulation of milk. In contrast to acid whey, sweet whey has a higher pH value (6.0-7.0) and a different chemical composition, which makes it a versatile but challenging material flow in industrial wastewater treatment. Due to its high organic
The cleaning of tanks and tank trucks is an essential part of industrial processes, especially in the chemical, food and water treatment industries. These cleaning processes produce highly contaminated wastewater that must undergo comprehensive treatment before being discharged into the sewer system or reused. In wastewater technology, the focus is on
Tank truck cleaning and, in particular, tank truck interior cleaning are essential components of industrial processes, especially in the chemical, food and water treatment industries. These cleaning processes produce highly contaminated wastewater which, due to its specific composition, must be carefully treated before being discharged into the sewer system or reused. The focus in wastewater technology
The submersible motor pump is an essential component in industrial water and waste water technology. It belongs to the group of centrifugal pumps and is characterized by the fact that it is completely immersed in the medium to be pumped during operation. This enables reliable and efficient pumping of water, waste water, sludge
Surfactants (short for "tensioactive substances") are chemical compounds that reduce the surface tension of liquids, especially water. They enable the mixing of hydrophilic (water-loving) and hydrophobic (water-repellent) substances, which makes them indispensable components in cleaning agents, emulsifiers and defoamers. Due to these properties, surfactants play a decisive role
The term TOC (Total Organic Carbon) refers to the total concentration of organically bound carbon in a water sample. The TOC value is a key parameter in water analysis, which is of great importance for both industrial water treatment and wastewater treatment. It serves as an indicator for the organic
The dry substance content (DS) is a key parameter in water and wastewater technology and describes the proportion of solids in a medium in relation to the total weight. It is given as a percentage (%) or in grams per kilogram (g/kg) and describes the mass of solids remaining after the water has been treated.
A drum screen is a mechanical filter system used in water and wastewater treatment to separate solids from liquid streams. The name is derived from the cylindrical, rotating drum, which is fitted with a screen mesh or perforated plate. The main function of the drum screen is to remove suspended solids, coarse
