ICE WATER MANAGEMENT
Closed Circuit Reverse Osmosis
Thanks to its high resistance to biofouling, CCRO new technology deployed by ICE Water Management is particularly effective for treating water that is sensitive to biological clogging, as in the case of water recovery from wastewater treatment plants.

Closed circuit phase (production phase)
- CCRO is fed with raw water and there is no concentrate release.
- Dissolved solids are accumulated into the recirculation loop.
- Concentrate is recirculated to create a strong tangential flow and flush the limit layer formed at the surface of the membranes.
Plug flow phase
When reaching saturation level, concentrate is released to the drain (plug flow) and a new cycle starts.
- 10-20 % energy savings.
- Descaling CIP frequency divided by 4 to 6.
- 20 % water savings in case of inlet water with high Silica and/or Sulphates content.
- High resistance to biofouling.
- Self-adaptability to variable influents.
- Reclaim from RO concentrate (or other high scaling potential waters).
- Water containing Silica and sulphates.
- Reclaim from treated waste water (or any other water with high TOC (1)).
- Variable/multiple resources management.
