A long awaited improvement for the large scale Reefkeeper or any other producer of high quality RO water. With this new device you can kiss TDS creep problems good bye.
All Reverse Osmosis systems suffer TDS creep. It is a fact. No name brand is immune not Kent, SpectraPure, Aqua FX, not even ours. Some method has to be provided to make longer system cycles, longer cycles = less TDS creep impact.
TDS creep is part and parcel of the Reverse Osmosis process.
Total dissolved solids creep. What is it?
In what type of application do I need to control TDS creep?
How does TDS creep impact my system?
Why do I use so many DI cartridges?
Why do my pumps, fittings, and system controls require so much maintenance?
How does anti tds creep work? What is this TDS creep?
TDS creep is the result of the membrane processing water under very low water pressure (system off) conditions. The membrane will still process water, not much water. Water produced under the low water pressure conditions is much lower in quality and higher in tds.
In what type of application do I need to control TDS creep? Any time you are replacing evaporation or using extremely small amounts of water at one time. In other words any time your system cycles repeatedly just to make a small amount of pure water.
Sump top off is one example of a small volume of water per on - off operation.
How does it impact my system? Each time you short cycle, the RO system feeds your DI cartridge much lower quality water than when your RO system is up and running. The lower quality water shortens DI resin life.
If your system is pump driven then you risk ruining the pumps and hammering the system to death, on/off/on/off 24 hours per day 7 days per week. Eventually causing fittings and pumps to fail or burst.
Why do I use so many DI cartridges? This happens a great deal when you use float valves to replace evaporation. Water evaporates gradually all day . Some electrical systems use timers to delay the operation of the R.O. system. The goal is to run the RO for as long as possible each time you use the system.
Why do my pumps, fittings, and system controls require so much maintenance? It is the constant on-off cycling. Even systems that aren't pump driven suffer water hammer each and every time the unit shuts off. Pump driven systems suffer the most.
Solutions: Various electrical switch systems exist, the problem is problems. Failures due to current spikes, outages, even snails climbing on to the switch (when used in sumps). I have tried for three years now to develop a completely mechanical system. I finally enlisted some help. When I visited the Chicago Water Quality Convention I spoke with Richard of Action Manufacturing and he resolved the hardware issues.
This complete storage with Anti TDS creep system comes fully assembled and is mounted on it's own tank . You will not need to go out a buy a Rubbermaid trash can.
How does it work? Your RO system is forced to fill a very large volume with water before it can turn off. The larger the volume the more water needs to be made to fill that volume. Longer run times, better RO system performance. You get much less production of TDS creep. Much longer DI resin life. Longer and fewer RO system cycles of operation. If you are operating a fish store that uses float valves to control evaporation or even a large scale reef keeper this device is must for you.
I know it sounds expensive, but it could actually cost you nothing. It may even begin to pay you. The average Reefkeeper will probably never recover the investment. However fish stores will benefit right away. Better and cheaper water for you and your customers.
The system is a round 18 inches by 33 inches tall. UPS will deliver it.
G.E.Merlin notes
If your tap water is under 200 PPM add this and a double DI to a Merlin and make tons of great water. No pumps no hassles.
Merlin systems in our experience have about a (92 %) rejection rate, not bad but not good enough for applications with high feed water tds.
