Product Q&A
Q:What type of RO membrane is avaliable in your company?
A:
In general, Aotun has Household/Commercial RO membrane and Industrial RO membrane for optional.
Q:What is Salt Rejection Ratio?
A:
The Salt rejection describes the quality of salt removed from the Reverse Osmosis feed water stream as a percentage. It's one of the key element of the RO membrane quality. Furthermore, other essential elements such as performance durability, stability, application scope in different region, and permeate flow rate at the same pressure will all be the important factors to judge the quality of the membrane.
Q:How often do RO membranes need to be replaced?
A:
RO membranes typically last 2-3 years, but lifespan depends on water quality and maintenance. Regular cleaning extends membrane life.
Q:Is the Salt reation of the RO membrane the higher the better?
A:
This will be depending on the feed water quality, if the feed water quality is good, even a 90% salt rejection membrane will be workable, if the feed water is with bad quality and with brackish water environment, a higher salt rejection above 95% is an ideal choice. For any membrane that meet the local drinking water standard will be a good membrane.
Q:How can we guarantee quality?
A:
Always a pre-production sample before mass production; Always final Inspection before shipment.
