PureFlush - How It Works from RainDance Water Systems
There are two flush time settings on our light commercial and whole house TV reverse osmosis systems, one for flush at system startup and the second for flush at tank full shut down. The most important is the flush at shut down, which replaces very high TDS concentrate that resides inside the membrane when the system stops running with clean product water. The startup flush is less significant since the shut down flush leaves clean product water in the membrane, but still provides a fresh membrane upon start up, especially if the system is left to sit idle for periods of time.
Another benefit with the PureFlush is that accelerated scaling of the membrane, which can happen when you leave the membrane soaking in highly mineralized water during down times, is avoided. When you connect to the flush inlet connector at the rear of the system it should be to a pressurized source of product water, usually to the outlet plumbing of the pump that is drawing water from the product storage tank and providing it to the house or usage.
This PureFlush technology is just one of the premium qualities RainDance offers standard with all of our whole house & commercial reverse osmosis and nanofiltration systems. Our engineers have held to their goal of over build and over design, resulting in quality assurance in the performance and lifespan of our membrane water treatment systems.
