OZONE4WATER - Cutting-Edge Ozone-Technology for Water Treatment

Goal: The increasing global health concerns due to the surge in urbanization, increasing water contamination, and increasing world industrialization are driving the ozone technology market globally.
O3 is usually produced by passing a stream of O2 through a corona discharge system, which provides energy to convert O2 to O3. The reactive nature of O3 typically limits the capability of O3 generators to produce O3 in concentrations greater than 15%, resulting in low yield and high O3 production costs. High O3 supply demands, the extended contacting time required in the reaction chamber, and the bulky size of the equipment (low gas-liquid mass transfer rates of O3), also constitutes a major impediment to the mass penetration of ozone technology in the water treatment sector.
OZONE4WATER will address these issues by developing a disruptive ozone-technology for water treatment including: (i) functionalized membranes for O3/O2 separation to obtain an O3-enriched gas stream, and (ii) the development of a low footprint ozone side stream contacting train for water treatment.

Dear Researchers,
We would like to welcome the two Research Fellows recently hired to work on the OZONE4WATER project:
Inês Rodrigues and Paulo Marrocos
Congratulations to both. Welcome to the OZONE4WATER team.
Best wishes,

Dear Researchers,
The kick-off meeting of the OZONE4WATER project (reference PTDC/EAM-AMB/4702/2020) was held on 8th July 2021 at the Faculty of Engineering of University of Porto, Department of Chemical Engineering.
The PI (Vítor Jorge Pais Vilar) presented an overview of the OZONE4WATER project to all participants (objectives, tasks, team, funding, time- line, milestones, etc.). Afterward, a representative of partners introduced the main goals of each company. Following, the PhD students enrolled in the project presented the main results obtained in the first months of the project.
Prof. José Carlos Brito Lopes, one of the inventors of the NETmix static mixer and founder of the collaborative laboratory NET4CO2, in which the NETmix is at the heart of various new technologies, conducted a presentation called “From NETmixtechnology to NET4CO2 CoLAB”. Afterward, the members of Simbiente, AdP, and Enkrott were taken to visit the NET4CO2 CoLAB facilities.
Best wishes,
OZONE4WATER TEAM
