Evac ROSYS
Custom-made reverse osmosis plants

Evac ROSYS reverse osmosis plants are reliable systems for the generation of freshwater. They can be configured for freshwater production capacities of between 20 and 1,200m³ per day. Evac’s core area of expertise is custom-made reverse osmosis plants that fit into any available space on board.

The pre-treatment process consists of multimedia filters and is designed to be low maintenance with minimal membrane cleaning, which ensures a longer membrane lifetime. Evac reverse osmosis technology is suitable for both new-build projects and retrofit or modernization of existing freshwater plants. For marine applications, we can offer of existing systems as well as full system construction while a vessel is at sea. Our full-service offering includes design, construction, delivery, and after-sales support, as well as installation supervision, testing, commissioning, and plant optimization.

Operating principle of Evac reverse osmosis plant

 

Evac RO graph

 

  1. The seawater pump feeds seawater to the multimedia filters, which are filled with finely granulated garnet to ensure maximum removal of suspended solids. A low filter velocity guarantees highly efficient removal and also reduces cartridge filter consumption.
  2. Cartridge filters remove suspended solids efficiently, which protects the pump, energy recovery system, and membrane to ensure a longer lifetime.
  3. The high-pressure pump feeds water to the membrane.
  4. Our spiral-wound semi-permeable membrane modules have high salt retention and consume minimal energy.
  5. After leaving the membrane, the water quality is monitored by the quality monitor, which automatically discharges water that does not meet USPH technical quality requirements.
  6. Our state-of-the-art energy recovery device can cut the energy consumption of the system by as much as 65 percent.
