In a reverse osmosis system, what is the recommended temperature limit to avoid damage to membranes?

In reverse osmosis (RO) systems, membranes are designed to operate within specific temperature ranges to ensure optimal performance and longevity. The recommended temperature limit for most RO membranes is typically around 85-90 degrees Fahrenheit. Operating at temperatures beyond this limit can lead to damage or degradation of the membrane material, affecting its filtration efficiency and lifespan.

Choosing 90 degrees Fahrenheit as the recommended temperature limit is appropriate because it aligns with the common specifications provided by manufacturers. Exceeding this temperature can result in increased permeability of the membrane, reduced rejection rates, and in some cases, physical damage such as warping or cracking. Therefore, understanding and adhering to this temperature limit is crucial for the proper maintenance and operation of reverse osmosis systems.
