Key Factors That Determine the Efficiency of a RO Membrane

Technology is evolving fast and drastically changing our lives for betterment. Considering the technological advances in the field of water management, RO plants are one of the most efficient systems currently deployed. A Reverse Osmosis (RO) plant is designed to conduct a sequence of advanced water purification methods to make the drinking water clean, purified, and even enriched with minerals. It’s not easy to understand the anatomy of this device without fair knowledge of the RO technology. But, it’s important to know about the various performance-related factors that determine the price of an RO plant while considering buying it.

Here in this web blog, we will help you find out about the different factors that affect the performance of an RO system. Let’s find out.

Temperature

With the rise in temperature, the rate of permeate flow and the salt passage percentage also increase. Hence, the pace of the permeate flow and the passage of salt is expected to be lower during winters as the feed water is mostly cooler at that time. On the contrary, the rate of permeate flow and percentage of salt to pass through is expected to be more during summers, while considering the operating pressure, TDS, and percentage recovery to be constant.

Pressure

Considering all the other factors as constant, the amount of permeate water produced will increase with the increase in pressure. However, it’s important for you to always check the design specifications mentioned by the manufacturer. Or else, if you operate the system at high pressure, the membrane might prematurely scale or foul, thereby limiting its performance.

Recovery

The relation between feed water flow and permeate flow is known as recovery. With the increase in recovery, the permeate flux gradually decreases and gets stagnated. It happens when the osmotic pressure is equal to feed pressure. However, with the increase in recovery, the salt retention decreases.

Concentration of salt in feed water

The osmotic pressure is typically a function of the salt concentration and its type contained in the feed water. With the increase in salt concentration, the level of osmotic pressure also increases. This proves that the amount of driving pressure for feed water required to reverse the osmotic flow’s natural direction is hugely determined by the amount of salt present in the feed water.

The final word

For individuals or organizations planning to procure an RO system for efficient water management, it is imperativeto do their research beforehand and choose a reputable manufacturer or supplier.
