RO / UF plants

Engineering and manufacture
of RO / UF plants.

Custom plants for process water, reuse and industrial concentration. Membranes, hydraulics, automation and cleaning defined in coordination with your engineering team.

Reverse osmosis and ultrafiltration plant
Custom engineering and manufacturing.
Two complementary barriers

Separate particles.
Reduce dissolved salts.

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.

01

Process water

Supply to industrial utilities, boilers and processes with defined quality requirements.

02

Desalination

Treatment of brackish or seawater with appropriate pretreatment and pressure.

03

Industrial water reuse

Recovery of treated effluent for uses compatible with its final quality.

04

Food and beverages

Production, washing and utility water according to food-process requirements.

05

Pharmaceutical and chemical

Treatment stages adapted to the process specification and its validation requirements.

06

Plant upgrades

Assessment of existing equipment, membrane selection and improvements to automation and operation.

Integrated system

Defined scope.
Clear interfaces.

We design and manufacture the plant around your specification: capacity, materials, operation and space. We coordinate interfaces for integration into the overall project.

  • Process engineering, projections and water and solute balances.
  • Skid manufacture, pretreatment, pumping and membranes.
  • Instrumentation, control panels and process automation.
  • Cleaning sequences, CIP circuit and maintenance access.
  • Commissioning, support and consumables.

Design criteria

Design the recovery.
Plan for the concentrate.

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.

  • Complete water analysis and temperature variation.
  • Required permeate quality and flow.
  • Solids, organic matter, salinity and scaling potential.
  • Operating regime, redundancy and available utilities.
Technical and integration criteria

Project questions.

What does Neptuno provide to the plant integrator?

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.

What are the advantages of combining UF and reverse osmosis?

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.

Can the control system be integrated with our plant automation?

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.

Do you also supply membranes and upgrades for existing equipment?

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.
