The Ozone solution for the removal of Micropollutants. Our new ozone transfer system for the elimination of micropollutants, such as pharmaceuticals, from wastewater, lowers the ozone consumption and reduces the required reaction time to almost zero. The heart of ELOZONIQ is the gas transfer system, the Roturi®. The Roturi distributes ozone finely and evenly to the aqeous soluion. This creates a large reaction surface for gas exchange.

ELOZONIQ Roturi – gas transfer of efficient Ozonation to avoid emerging conatiminants


Small Footprint

Due to the highly efficient ozone transfer, the contact time for the elimination of trace substances and micropollutants is very short, between 3-5 minutes. This reduces the tank size for ozonation using ELOZONIQ by a factor of 3-6 compared to conventional ozonation. In addition, there is no minimum height for the tank.

Compact and flexible - ELOZONIQ Roturi ozonation micropollutant removal
Low construction costs and short construction times

Due to the compact design, the construction time for an ELOZONIQ plant is short and the construction costs are low as large and expensive concrete basins as a reaction volume for the ozone with the pollutants are not required. All system components can be pre-assembled on frames in the factory, which reduces assembly time on site to a minimum.

ELOZONIQ - compact ozonation for the degradation of micropollutants with Roturi
Compact design and mobil

Due to the compact and modular design, the ozone entry system is also ideally suited as a supplement to existing activated carbon systems for the fourth cleaning stage.
The smaller tanks can be built without a minimum height, compared to conventional ozonation due to short contact time. The modular concept allows capacity to be expanded in the future.

Due to its compact design, it is possible to install the ELOZONIQ system in a container. As a result, we can offer you new concepts for the fourth cleaning stage with ozone. This includes systems for rent as well as mobile systems.


The efficiency of the gas transfer and thus the degradation of micropollutants is almost independent of the flow. In contrast to other gas transfer systems such as Venturis, no minimum throughput of water or ozone is required for efficient ozone input. This makes ELOZONIQ flexible in terms of flow capacity.

Efficient and safe

The ELOZONIQ process is operated at ambient pressure and temperature. It is a fully monitored and automated process. Due to the efficient ozone transfer, a lower use of ozone is sufficient to achieve very good degradation efficiencies.

Operating Principle

  1. Operating Principle Wastewater is fed to the ELOZONIQ plant.
  2. The Roturi® enables a highly efficient and immediate gas dissolution. With in-line operation, a specially shaped rotor creates a large reaction surface for gas exchange - without significant pressure drop. The result is a low energy consumption with a wide operating range in terms of water flow rate and ozone input.
  3. Post reaction, the treated wastewater is fed to a stabilisation tank. Due to the efficient dissolution of the ozone via the Roturi®, a contact time of only 3 to 5 minutes is sufficient. Therefore, there is no need for large reaction tanks or chambers. This makes ELOZONIQ very compact compared to conventional state-of-the art ozonation.
  4. Depending on local requirements, a post-treatment step (sand filtration, activated carbon) to eliminate possible by-products is applied before the cleaned water is discharged to the environment
