Permeate Flush

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.

Panel-Mount

Flow Meters and pressure gauges with 316 stainless steel needle valves for precise control of production and wastewater

5 Micron Magna Pre-Filter

With 36 Square Feet of Media for long life

Stainless Steel Membrane Housing

These housings provide the best longevity with ease of replacement

Highest Rejection Rates

Up to 99% rejection

Defender Controller With TDS Meter

Enables you to continuously monitor water quality

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.
