ESRODESAL
Energy Self-sufficient (off-grid) compact plug-and-play seawater Reverse Osmosis DESALination units
The Concept
Energy Self-sufficient (off-grid) compact plug-and-play seawater
Reverse Osmosis DESALination units
with alternative energy supply sources (solar, wind, waves and/or power sets)
for mobile or land-based decentralized potable water procurement
based on ROCHEM’s open channel reverse osmosis membrane modules.
Additional features:
- indirect seawater intake and partial pre-treatment systems for sandy and karstic shores (e. g. DRENACAP for up to about 1,000 m³/day, NEODREN or NEODREN-PLUS for any seawater intake capacity) avoiding impingement and entrainment of aquatic organism, avoiding pre-treatment chemicals, minimizing the use of cleaning chemical
- pre-treatment of the seawater with solar powered electrodialysis in order to reduce the specific energy demand and allow for a design with lower operating pressure
- use of optimized high-pressure pumping systems with integrated energy recovery devices or energy saving design

Case Studies
Belgian Army
Mobile unit for the Belgian Army, approx. 30 m³ potable water per day from any source
Naval Industry
Units installed in the naval industry, e. g. on yachts or drilling rigs, approx. 10 m³ potable water per day from seawater
Hospitality industry
Units for seawater desalination, e. g. on cruise ships, in hotels, resorts etc., approx. 100 m³/day (up to 1,000 m³/day)
