Closed circuit reverse osmosis (CCRO™) systems

 
 
 

The performance benchmark for reverse osmosis

Desalitech’s closed circuit reverse osmosis (CCRO™) systems are rapidly replacing traditional water purification methods. Our global customers rely on the consistent performance and ease of operation, saving significant costs through reduced maintenance, maximum water recovery rates, and lower energy consumption.  

 
 
 
 
 
 
 
 
 
 
 
 

What is CCRO™?

Desalitech’s patented closed circuit reverse osmosis (CCRO™) technology establish a new benchmark for reverse osmosis performance. The CCRO systems work by circulating water through a single stage of membrane elements until the desired recovery level is achieved instead of using complex traditional multiple stage methods. Brine is periodically replaced with fresh feedwater without stopping permeate flow. Recovery is flexible and can be set at the system control panel. Over 97% recovery has been demonstrated in single stage ReFlex systems, reducing brine waste by 50% - 75%. 

ReFlex products operate reliably on feedwaters that challenge traditional RO systems. The cross flow required for ReFlex RO membrane operation is controlled with an internal circulation pump. Frequent and complete brine flushing prevents scale precipitation and disrupts bio fouling, making very high recovery rates possible even from mineral-laden or contaminated feedwaters. In addition, ReFlex products offer unmatched flexibility. Permeate flow, cross flow velocity and system recovery are independently controlled, supporting process optimization.
