Reverse osmosis technology is used to increase water purity by removing salts and other contaminants.
The recovery rate of the membrane system, a crucial performance indicator, typically attracts considerable attention when utilizing reverse osmosis membranes to treat raw water. A high rate of recovery indicates a high water output capability.
Let’s understand the concept of recovery rate in RO Plants, and the ways to improve it.
How much recovery rate is required in RO Plants?
Due to the device's multiple membrane components and drawn-out water supply process, the real system recovery rate is normally above 75% and occasionally even exceeds 90%. The small-scale reverse osmosis system's recovery rate is frequently low.
The quality of the feed has a significant impact on the reverse osmosis recovery rate. The impurities are typically organic and inorganic salts, which
1) increase osmotic pressure, and
2) clog the membranes of the system.
How to improve RO Recovery rate?
1) Enhancement of Feed Pre-Treatment
The troublesome ions that induce scaling can be removed from the feed using novel membrane technology. The employment of NF membranes to cut the bivalents (Ca2+, Mg2+, and SO42-) that are certain to cause issues for our membranes is an excellent example. Hence, we may make sure that our system is better and more permeable.
Using antiscalants is an additional choice. These are chemical additions that postpone the synthesis of calcium magnesium and bicarbonate, allowing water to pass through the membrane before scaling takes place.
2) Modern Membrane Engineering
New membranes with enhanced:
• Surface Area
• Maximum burst pressure
• Resistance against biofouling
• Diameter of the spiral wound
These can recover water more quickly than their predecessors, and improve system efficiency.
3) Fresh System Setups
The market has developed new system configurations that permit,
• Focused Re-circulation
• Focused Staging
• Integrate Staging
4) Brine Treatment Technologies
The RO concentrate (Brine) is subjected to significant work to extract as much water as possible, and numerous technologies have been created that enable the system to operate with a Minimal or Zero Liquid Discharge.
These improvements can aid in system optimization and raise the RO water plant recovery rate.
