Dagua, ozone generators, ozone, ozone production Dagua offers a unique value proposition for local and international communities with large-scale drinking water treatment projects (from 5,000 to 500,000 m3/day). Delivering highly effective water purification and disinfection, Dagua’s ozone-membrane process occupies up to 40% less space than conventional coagulation systems. With coagulation eliminated from the treatment process, the DaguaFlo solution has a clear edge over the competition! To meet the needs of small- and medium-sized communities (500 to 5,000 m3/day), Dagua designs and manufactures prefabricated treatment plants that purify water to the most stringent quality standards. Available with or without housing, they are installed as a single unit between the source of the water to be treated and the distribution network. The plants are designed according to the specific parameters of a project and allow for an anticipated increase in water flow. Dagua also offers ozone generators for municipal and corporate applications such as the treatment of effluent, cleaning and the disinfection of industrial processes. Dagua's ozone generators represent an innovative solution for the replacement of chemical cleaners. Dagua also manufactures turnkey ozonation systems, with housing, measuring instruments and air and oxygen generation included. Our ultra-compact systems include a PLC for remote operation and monitoring. Drawing on years of R&D experience, Dagua has developed a patented process for the cleaning of ultrafiltration membranes using ozone microbubble technology. Ozone microbubbles are finely diluted in water to deeply clean capillaries and prevent membrane fouling. Dislodging accumulated solids without chemical cleansers, this process delivers significant cost savings. With this innovative technology, frequent downtimes for chemical cleanings are a thing of the past as well.

Dagua's ozone generators

Ozone generators



Dagua now offers municipal and private sector customers its high-efficiency ozone generators for tertiary wastewater treatment.


Dagua's ozone generators use ceramic plate technology to provide greater wear performance, durability and ease of service than corona discharge systems.


This ultra-compact solution also has a footprint up to 4 times smaller than that of corona discharge systems with similar capacities.


The system uses a programmable logic controller for ease of operation and monitoring. Dagua's highly flexible ozone generators have the added benefit of modular design, meaning that additional units can be connected in parallel to increase production capacity.

Properties of Ozone


Ozone is a natural gas that is produced when oxygen is exposed to an electrical field. Widely used by municipalities in Europe and North America (e.g., Los Angeles, Montréal, Nice) for almost a century, ozone is considered to be the most powerful oxidizer available for safe water treatment and requires only a short contact time.


Ozone has a number of exceptional properties, including the following:


1. Disinfection, including the elimination of viruses, bacteria and coliforms in water


2. Reduction of metals (e.g., iron, manganese, cyanide) into precipitable form


3. Odour elimination


4. Colour reduction


5. Oxygenation and revitalisation of water


6. Elimination of algae


7. Reduction of pharmaceuticals in water
