Modularity of the SSD system
DU
RO CT
Modularity in quantity of potable water produced
The system has been dimensioned for 48 m3/h of potable water: the scale up is modular with the formula n x 48 m3/h.
Modularity in quality of water produced
The smart RO desalination process is the core of the system, in case of higher quality of water (DEMI or UltraPure Water) the system can
be easily integrated as a module in input of the other processes. In case of lower quality of water (desalinated for agriculture and not
potable) the SSD configuration shall be without the potabilization “module”.
Modularity in quality of water to be treated
The desalination process has been dimensioned with a quality of salt water with 35,000 ppm of salt concentration.
In case of brackish water, the salt content is much less than 35,000 and the technical requirements of the RO process are less critical:
SSD system shall be simply less complex in the desalination process and it will be cheaper. In case of salt concentration higher than
35,000 ppm, it is necessary to make a detailed study for the RO membranes, respecting the modularity in output of the system. An
higher salt concentration means more energy required per m3 of desalted water: SSD will be more competitive in cost efficiency of fresh
water generation, especially for remote areas.

World-New PV Smart RO (Reverse Osmosis Desalination) system
BISoN Bifacial Tracker
KEY FEATURES
SSD (Solar Smart Desalination) system, as a world-brand new product for solar water purification based on Reverse Osmosis (RO)
SSD has been specially designed and optimized for off-grid configuration, using photovoltaic (PV) Bifacial High-efficiency Modules with
sun tracker, combined with Genset and small UPS for back–up purpose only, in order to guarantee the delivery of purified water 24/7.
The optimization of the RO Desalination process and the PV Power Generation design adapted to different power requirements of Desalination
Process, combined to an optimized storage of water, releases a patent pending, innovative and cost-effective water purification system,
maximizing the use of solar energy to produce directly purified water and minimizing the storage of electricity in the batteries and the
fuel consumption at the Genset.

High volume of water stored
Business model flexible and customer oriented
The winning point is the possibility to store water processed
instead of energy into batteries. In the smart RO, the sun directly
goes in the desalination process without storage in batteries.
The big tank of desalted water has the double scope to optimize
the renewable energy generation process and to guarantee the
water availability. The role of the back-up system is not to store
energy, but optimize all the energy not used by the Smart Reverse
Osmosis (RO).
