Nanofiltration/Reverse osmosis with CO2

Increased lifetime of membranes

GAS APPLICATION

CO2-injection is used in both avoidance measures and in cleaning cycles:

 

pH-adjustment of the inlet water prevents scale build-up on the membranes. Depending on further use, CO2 is the acid of choice
A rinse foaccording the CO2-water flush process* cleans spirally wound membranes of organic deposits and particles. Water satured with CO2 is used as rinsing water. The targeted degassing of CO2 in the spacer channels leads to a significant increase in the rinsing turbulence and causes efficient removal of contamination from the spacers.
Advantages compared to chemical cleaning:

Very short cleaning time: 5 minutes compared to 8 hours
Higher cleaning efficiency for the spacers  
Environment-friendly: the CO2-footprint is reduced by up to 75 %
Existing plants can be retrofitted  
Low investment and operating costs
