Seawater desalination plant with reverse osmosis ZSW from 2.8 to 45 m3/hour


AZUD WATERTECH ZSW desalination plants

Compact desalination plant with reverse osmosis for seawater, skid-mounted or with sea container, to supply osmosed drinking water for industrial applications, hotels, small communities or towns, hospitals.


Seawater desalination plant ZSW

Seawater desalination plant, model: DW ZSW. For water with TDS: 35,000 – 45,000 mg/l

Technology used: Zeolite deep bed filtration + microfiltration cartridges + SW reverse osmosis membranes for seawater.

Production flow rates: 2.8 – 5.6 – 11 – 18 – 24 – 42 m3/h*.

* Tailor-made water treatment plants for high production flows.



AZUD WATERTECH ZSW desalination plants are a highly durable, compact and factory-tested solution for Plug&Play installation and immediate start-up.

The automation and instrumentation of the plants allows them to operate completely autonomously to reduce operating costs and ensure efficient long-term performance.

They have a user-friendly interface, with remote control option, to facilitate system monitoring and control.

  • MECHANICAL FILTRATION, without chemicals or unnecessary consumables.
  • ZEOLITE filter bed for suspended solids removal.
  • Optimized LIFESPAN for reverse osmosis membranes for desalination. Thanks to an improved physical-chemical pretreatment.
  • CONTROL and MONITORING system to guarantee the quality of drinking water.
  • EASY to operate and maintain

How is it different from other desalination plants that are assembled on site:

  • Less time on site for installation and start-up.
  • We optimize system performance and minimize energy consumption.
  • We guarantee the quality of the water supplied.
  • We reduce the consumption of consumables and chemicals.
  • We extend the useful life of the plant and its components.
