The invention relates to a carrier insert for accommodating and maintaining the biofilm culture of fluid cleaning structures, which contains a spatial web made of staple fibres using the hosiery method. The characteristic feature of the invention is that the web () has internal textile units () joining each other in intermediate complete nodal points () and situated between the complete nodal points (), and external textile () units situated along the edges () of the web (), where in the case of at least a part of the complete nodal points () there is an even number of internal textile units () guided into the given complete nodal point (), the internal sides () of the external textile units () situated along the edges () of the web () are connected to a complete nodal point () each, and the external sides () of the external textile units () are provided with connection points () for joining the structure (), and via the connection points () the web () is attached to the structure () in a fixed position.

The equipment has a main reaction (I) and an anterior reactor (II), as well as facilities for feeding in untreated sewage, removing cleaned water and sludge and aerating the wastewater entered into the main reactor, and a mixer () situated in the anterior reactor (II), and it is characterized by that between the main reactor (I) and the anterior reactor (II) there is a facility or there are facilitates for the recirculation of wastewater. In the course of the procedure, between the anterior reactor (II) and the main reactor (I) the waste-water aerated in the latter reactor and mechanically stirred in the former reactor is recirculated, and so the transformation of the nitrogen content of the biologically decomposable pollutants by nitrification takes place in the main reactor, while the biological elimination of the nitrates created in the course of the nitrification (denitrification) takes place in the anterior reactor, and as a result of the anaerobic processes biological phosphorus elimination is also ensured ().

Method and apparatus for the biological activated sludge treatment of wastewater

The invention relates to a process for contacting a gas with a liquid, wherein the liquid to be contacted is led in the form of a central liquid jet leaving a nozzle through the space containing the gas to be contacted into the liquid to be contacted. In accordance with the process of the invention, a part of the gas and/or the liquid to be contacted, or the total amount of the gas, or a part of the liquid and the total amount of the gas are led onto the surface of the central liquid jet in the form of gas or liquid jets directed to the surface of the central liquid jet.
