Process water
Supply to industrial utilities, boilers and processes with defined quality requirements.
Custom plants for process water, reuse and industrial concentration. Membranes, hydraulics, automation and cleaning defined in coordination with your engineering team.

Ultrafiltration and reverse osmosis act on different fractions of the water. Selecting one, the other or a combination depends on feed composition and final use.
Quality is delivered by the complete system: pretreatment, membranes, operating control and, where required, final conditioning.
| Aspect | Ultrafiltration · UF | Reverse osmosis · RO |
|---|---|---|
| Primary objective | Retain fine solids, colloids and microorganisms according to membrane selection and integrity. | Reduce dissolved salts and other solutes using a semipermeable membrane. |
| Typical uses | Clarification, a particle barrier and RO pretreatment. | Low-salinity water, desalination and polishing for reuse. |
| Parameters to control | Turbidity, flux, transmembrane pressure, integrity and cleaning cycles. | Conductivity, recovery, pressure, rejection, scaling and fouling. |
| Resulting streams | Permeate and wash water or concentrate, depending on configuration. | Permeate and concentrate requiring a defined destination. |
Supply to industrial utilities, boilers and processes with defined quality requirements.
Treatment of brackish or seawater with appropriate pretreatment and pressure.
Recovery of treated effluent for uses compatible with its final quality.
Production, washing and utility water according to food-process requirements.
Treatment stages adapted to the process specification and its validation requirements.
Assessment of existing equipment, membrane selection and improvements to automation and operation.
We design and manufacture the plant around your specification: capacity, materials, operation and space. We coordinate interfaces for integration into the overall project.

High recovery increases the concentration of salts and other components in the reject stream. The design balances water production, scaling risk, energy consumption and concentrate management.
Engineering and manufacture of the membrane stage, hydraulic design, instrumentation and automation. The scope can cover a process unit or the complete treatment system, coordinating interfaces and responsibilities with your engineering team.
UF provides a particle and colloid barrier that helps stabilise the RO feed. Reverse osmosis completes the separation by acting on salts and other solutes. This combination supports water reuse and process water projects with demanding quality targets.
We define instrumentation, signals, cleaning sequences and communication requirements with the engineering team. This coordinates membrane operation with tanks, pumps and upstream and downstream stages.
Yes. We review the installation and water quality to select replacement membranes and improvements to pretreatment, cleaning or control. The objective is to recover capacity, stabilise operation and optimise system cost.
Send us your flow rate, water analysis and treatment objective.
We will review equipment selection, integration and the data needed to size your project. You can attach your water analysis or P&ID to your email.
