Drinking water treatment plants: high flow rates

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!

Drinking water treatment plants: small and medium flow rates

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.

Microbubble-based membrane cleaning process

Drawing on years of R&D experience, Dagua has developed a patented process for the cleaning of ultrafiltration membranes using microbubble technology. 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.

DaguaFlo Technology

Dagua’s unique patented treatment process involves an innovative combination of ozonation and membrane filtration. Conventional membrane filtration often presents significant technological challenges, including the excessive fouling of membranes, frequent chemical cleaning and unnecessary water loss through the regular maintenance of system components. The DaguaFlo solution lets you avoid all problems arising from the complex management of chemical products.

Dagua’s certified process requires no chemicals for its operation and regular maintenance, and uses only a small quantity of water (5 to 10 times less than some membrane alternatives) to clean plant components.


This video presents the operation of DaguaFlo technology in the treatment of surface waters and production of drinking water without using chemicals that are commonly used in conventional technologies.

The superior performance of the DaguaFlo technology lies in the combined use of ozonation and ultrafiltration membrane processes for effective disinfection of water and removal of contaminating substances, leading to the production of drinking water.
