The highly efficient bioreactor DVZ-JZR (Jet-Zone-Reactor) represents an innovative aeration technology for sewage treatment and operates according to the injector principle.
Due to the high throughput performance and the very compact construction of the reactor this treatment technology has very low space requirements. Up to 75 % of the space requirements of a conventional sewage treatment plant can be saved by using the DVZ-JZR technology.
Its special construction without moving parts ensures zero maintenance and high operational safety.
The reactor is divided into two parts: the jet zone and the reaction zone, which also determines the dwell time.
The sewage to be treated is introduced together with activated sludge via a special two-substance nozzle system with integrated aeration into the lower part of the jet zone. The bacteria contained in the waste water and the biological sewage substrate are intensively mixed with very fine air bubbles.
The multiple deflection of the medium creates a loop flow in the jet zone, resulting in optimal loading of the biomass with substrates. Part of the three-substance mixture flows from a baffle plate into the upper reactor zone (reaction zone), where the bacteria form larger floc agglomerates and react until they are exhausted.
The membranes of the Biomass Separation Unit “DVZ-BMSU”, which are made of a special titanium alloy, can rightly be described as almost indestructible. Due to its 100 % stainless steel construction and the deliberate avoidance of materials such as plastics and ceramics, this unique membrane technology is insensitive to high pressures and temperatures, as well as critical pH ranges. A key feature that also makes the modules of the “DVZ-BMSU” unique is “CIP” (Clean-in-Place). Here, the modules are individually decoupled from the treatment process and run through a cleaning process. During this, the sewage treatment plant remains in operation (min. two membranes).
The membrane modules are arranged outside the reactor chamber or tanks so that they are always easily accessible, easy to maintain and can be quickly replaced in exceptional cases thanks to a special quick coupling system. It is never necessary to open the treatment plant, as it is the case with submerged membranes, for example.
Due to the possibility of returning the membrane modules to “new delivered condition” through this cleaning process, an extremely long service life is realised (>20 years achievable) and the necessity of continuously changing the membranes is eliminated.
By using the “DVZ-BMSU”, which operates on the basis of the cross-flow principle, we achieve a continuous permeate quality where we consciously speak of clear water instead of “just” clean water!
The addition of disinfectants for final treatment, such as chlorine and even UV treatment, is not necessary in any case.
