Reverse osmosis water production rate
Thread Content
Does every plant aim to increase the water production rate of reverse osmosis? Was there already a large margin during the design phase? What would happen if it were increased? Also, reverse osmosis systems are now all controlled via variable frequency drives; so how can the water production rate be increased?
The designed water production rate is highly dependent on the quality of the water entering the reverse osmosis membrane, and generally, there is not much room for increase. Increasing the water production rate beyond its limit reduces the membrane’s lifespan and raises energy consumption; it’s okay for short-term use.
The recovery rate is designed reasonably based on the water quality; it should not be increased in a reckless pursuit of higher values, as stable operation over a long period is key
The general design target is 75%, but in reality it cannot be achieved
As the recovery rate increases, the membrane lifespan decreases
