Reverse Osmosis

Water desalination with Reverse Osmosis membranes.

Water desalination plant Hydra MA, to provide desalinated water for irrigation and industrial use, through brackish or sea water desalination with reverse osmosis membranes.

The RO process is based on the application of high pressure to a concentrated solution of salts in contact with a semi permeable membrane (which allows the passage of water and retains the salts), to reserve the natural process of osmosis to obtain a salt-free water (permeate) and a rejection (brine) with high salt concentration.

Hydra MA solution

1. Reverse Osmosis membranes desalination, to remove dissolved pollutants in water, such as mineral salts, heavy metals, pesticides, radioactive elements, etc.

2. More energy efficiency than other desalination systems (distillation).

3. Physical-chemical pretreatments and automatic-scheduled preventive actions to prevent RO membranes clogging with suspended solids, salts precipitates and/or bio fouling.

4. No need of chemicals reagents and unnecessary consumables which generate cost and dependence.

5. Fully autonomous operation, ensuring the water quality and the maximum equipment protection. No need of qualified and permanent staff.

6. Very compact and modular plant, with simple and immediate installation and commissioning.
