AquaClean — closed-loop industrial water recycling
Turning polluted flows into sustainable cycles.
RYBSEN developed AquaClean, a patented closed-loop industrial water recycling system. Zero discharge. Zero waste. Already deployed across 14 machines in Tunisia, Algeria, and Côte d'Ivoire.

The problem
Every day, thousands of industrial sites discharge chemically polluted water with no accessible recycling solution. In offset printing, fountain solution — loaded with solvents — goes straight into the sewage system. This waste has a cost: for the environment, for groundwater, and for the businesses themselves.
AquaClean
AquaClean captures polluted industrial water, purifies it in real time through 6 filtration stages driven by multi-parameter AI sensors, and returns it endlessly into the production cycle.
Since 2019
Since 2019, RYBSEN has deployed 14 AquaClean machines across both R&D and commercial operation.
~135,000 m³
of clean industrial water saved — the equivalent of more than 54 Olympic swimming pools
~94 t
of CO₂ avoided
These figures are a conservative estimate based on the confirmed average performance of our commercial units, extrapolated with a prudence factor for the R&D prototyping phase (2019–2023). Full methodology available on request.

Today: industrial printing. Offset press fountain solution is one of the most polluting and wasted water flows in the graphics industry. AquaClean already offers a field-proven answer.
Tomorrow: textile, agri-food, and beyond. AquaClean is designed to adapt to any water-intensive industry. A V2 version, currently in development through a Tunisia–France research partnership, opens the way to new high-water-stress sectors, including oil & gas.
Field proof
Nouha Eco Print
Sfax, Tunisia
“I spend €120,000 a year on chemicals. There has to be a better way.” After installing AquaClean, the results exceeded expectations: up to €85,000 in yearly savings, a return on investment in under 12 months, and a 90% reduction in solvents used.
