Demineralized water for paint lines, surface pretreatment and rinses.
Process water and demineralized water from wells, city supply, water trucks or recovered water. We design, build, install and operate your reverse osmosis plant, from 1 to 2,000 m³ per day.
Reverse osmosis pushes water at high pressure through a membrane so fine that water passes and almost all dissolved salts, hardness, silica and ions stay behind. The result is demineralized (DI) water or process water with the conductivity your line needs.
An industrial RO plant is more than the membrane skid: pretreatment decides how long membranes last and what the plant costs to run. That is why we start with a water analysis and design the full train, from the inlet to the treated water tank.

A typical demineralized water train. Each stage is defined by your water analysis.
Any process that needs water with low dissolved salts or controlled conductivity.
Demineralized water for paint lines, surface pretreatment and rinses.
Feed water free of hardness and silica to prevent scaling and downtime.
Purified water for formulation and equipment cleaning.
Demineralized process water with stable conductivity.
Water for surface treatment rinses and cooling.
Process and utility water with consistent quality.



We do not just sell equipment: we hand over a working plant.
Same equipment, same engineering. Rental and pay per use require no upfront investment, subject to technical, financial and contractual evaluation.
One-time investment. You own the asset and can depreciate it.
See how it works →Fixed, predictable monthly fee, no upfront investment.
See how it works →We provide and operate everything; you pay per liter or m³ treated.
See how it works →It depends on flow, feed water quality, required quality, civil works and installations, so we quote after a free assessment. You can also rent it or pay per use, with no upfront investment (subject to technical, financial and contractual evaluation).
From 1 to 2,000 m³ per day (1,000 to 2,000,000 liters per day), sized for each plant.
The reject (concentrate) carries the salts removed by the membranes. Many plants send it to drain; we can treat it to recover a large share of that water and return it to the process.
Yes. We work in English, quote in US dollars or Mexican pesos and build to your corporate specifications.
Yes. We offer maintenance plans and, under pay per use, we operate and maintain the system while you pay per liter or cubic meter treated.
An engineer reviews your information and gets back to you, in English. Free, no obligation.
