At US Water Systems we realize that effective water treatment isn't done using a one size fits all approach. That why we have a team of Water Treatment Specialists that can assist you in building a custom system to address your particular water problems.
Permeate flush is an option for our RO systems that can provide a membrane flush directly after shutdown. This flush option is called Permeate Flush because it uses clean water produced by the RO system (permeate or product water) to flush the membranes after shutdown. This is extremely effective when membrane life is going to be a problem. In cases where the dissolved solids of the feed water are elevated this is crucial to membrane life. This may not always be the total dissolved solids (TDS).
In some cases, one particular element such as silica is elevated, and permeate flush is used to make sure it is flushed from the membrane after shutdown. If concentrated solids are left in the membrane housings after shutdown they can precipitate (fall out) from the solution. When this happens the solids remain in the membrane housings until the RO system starts up again. This causes them to be pushed into the membrane instead of flushed as they would be during operation. The membranes eventually become clogged with these solids reducing the lifespan.

NOTE.
The water industry uses the RO System Production Rating as a standard and it is best suited for “perfect water conditions”, which is rare in any case. An ideal condition is specified as “water less than 2000 ppm TDS (Total Dissolved Solids) with a temperature of 77 degrees F”. If your TDS is dramatically higher or your temperature is dramatically lower, the system production will be greatly impacted.
If your TDS is above 2,000 ppm, or you are in a region where your water temperature is lower or higher than 77 degrees F you should consult with one of our Certified Water Specialists before selecting a system. In certain cases, a pretreatment application may be necessary to achieve your water treatment goals.
Overall rating: 5.0 / 5 from 6 reviews.

"Jake in sales helped me all the way start to finish. Gave him my water sample and guided me to the ideal unit. Based on his expertise he gave m the good, the bad (reality) and help us get into what i think is going to be the correct size. Instructions for assembly were clear to follow. We went with the 16kgpd and final off the well product is closer to 11Kgpd with the cold northern MN ground water. We are at this point happy would do it again with US Water Sys."

"Easy to install. The system is performing well so far 3 weeks of operation."

"I’ve been running my Defender series for about a month now and am very satisfied. From the moment I unpacked it I could tell that it was a well thought out and assembled machine. I would recommend it to anyone who needs a commercial RO system."
— Fifth F. (5/5)
"Yes, it is all a big purchase for residential. Got the 2,000 gpd Defender, with Permeate Flush,and Anti Scalent . We have a water well and the TDS is 2000. A day after running the system is now reading 36 in the tank. Bought the Calcite Remineralization. It brought TDS up to 99 in the house. The repressurization pump keeps good pressure to the house. Got excellent customer service on a Saturday afternoon. No leaks on machine. Well packaged for shipping. This was a good purchase and product. Working well with the hard water here in west Texas."
— David S. (5/5)
"I have had my system for 3 months and I am completely satisfied with the whole experience with this company. I was skeptical about having to spend the extra money, but once I received my Unit and really looked at the quality of the components I knew I made the right decision. The sales team was very Knowledgeable and competent in solving my hard /salt water issues from a well in north Florida. I Installed the system myself and had to call technical support several times in the process which was answered promptly by a great team of guys. This system has changed my whole water experience in my home! I Highly recommend this company!"
— Walter (5/5)
"I installed a 4,000 GPD system 6 months ago and have never had the system go down for any reason. The installation process was really straightforward and the technical support team helped me when I called with questions."
