What is the water ratio for the system with RO?

That depends on the membrain that the R/O system uses but a typical 50 gal per day membrain is a 4 to 1 ratio. That is it wastes 4 gallons for every one that it produces. If you go to a 100 or 150 gallon per day membrain they will waste less water but they will also produce water that has a lot more disolved solids in it (less filtered). We use the standard 50 gallon per day membrains unless someone asks specifically for something else.

1 perfect gallon for every 2-3 gallons made...give or take a gallon of so, depending on your water quality and use. - J

I would be worried if the manufacturer does not answer u back. The R O membrane stops most dissolved solids, which are small me ulema and bispenol-A or BPA is a fairly large molecule. Like it or not it is in our water, bottled or tap. The system seems to be made out of HDPE plastic, which is better than other types. The tank is stainless steel, hence no bpa, so as long as you do not expose ur sistem to acid or direct prolonged light you are safe for the first 2-3 years. I would recommend you get the 5 stage system, because the alkaline filter says "electrolytes and etc." no one answered when I asked what etc mean, so I removed it. 5 stage is $169.

The recommend RO Membrane is the OM1-S6-S06 OmniFilter Reverse Osmosis Membrane.

Use a TDS meter to tell when the membrane needs changing. When the TDS starts to go up its time to change. I typically get 18 months per membrane, but our water is notoriously clean. I only use my RO/DI system for making water for my reef tank.

RO is known to remove salts and minerals which make the taste bland. I prefer not having RO because of the amount of water waste it takes to generate the pure water and the water needs to be stored in holding tank because the pressure and amount of on-demand water from RO systems does not compare to the tap. Tap is perfectly safe by itself. Personally I just think RO is a bit overboard unless you have a good reason to use it (i.e.: ground water, wells, fracking, etc)

This faucet will not work for your RO system. This faucet is for a standard drinking water tap. The faucet you need for your unit is a air gap faucet. Search for reverse osmosis air gap faucet. Hope this helps Rod B

.8oz / 1 gallon of water is the correct concentration. To make it even easier there is a built in measuring cup molded into to container. Again .8 oz for every gallon if water, that should give you a .06 percent solution.

Yes, the RO process removes up to 98% of everything and the DI filter removes all ions left after the RO process. Giving you distilled quality water for use in lab or aquarium use. afwfilters

45 psi will work although it's on the lower end of the spectrum. All RO membranes operate more efficiently with higher psi. You could add a booster pump to increase the rejection rate and produce RO water faster.

Should work really well. You will need a separate RO storage tank and pump though.

I recommend the Watts 7-Pack 1-Year RO filter bundle for a five-stage manifold. This will allow you to change out two carbon block and one sediment filter at the six-month mark, and the polish filter annually. The RO membrane should last a good 5 years (depending on your water supply quality) if you are diligent about replacing the carbon block filters--these remove chlorine and/or chloramine in your supply water before it reaches the RO membrane. These chemicals will degrade the RO membrane and shorten its lifespan. Once you do replace the RO membrane, check out the $40 50 GPD model on Amazon; for basically the same money you pay for the 24 GPD membrane that comes standard on these units, you can double your flow rate. http://www.amazon.com/Watts-Filters-Premier-5-Stage-Replacement/dp/B001ACTM1A/ref=sr_1_2?s=home-garden&ie=UTF8&qid=1378220816&sr=1-2&keywords=watts+premier+filters

Unfortunately no, this system is a much larger system and needs to be run off of one of the spouts outside of your house. It needs a good amount of water pressure to produce RO water. And this also has a waste water port that needs to drain somewhere as you use the hydrologic system. I use it to fill up trash cans ( 40 gals +). I would suggest something a little smaller for what your looking for. Good luck!

According to the RO System Performance Data Sheet, the RO-45 has a higher TDS Reduction % (96.7) than the RO-90/RO-PERM's (85.1). Of course, it is assuming that your Daily Production Rate L/day (G/day) is 40.1 (10.6) for the RO-45 and 130.5 (34.5) for the RO-90/RO-PERM. So, yes, the other comments are correct: If you have a high demand for R.O. water in your household, then you may want to go with the RO-90/RO-PERM. Just to give you additional information, my RO-90 currently has a rejection rate of 95-96% even though my family and I use less than 130.5 L/day (34.5 G/day).

I believe the ro water is OK to drink but it is not good to drink the ro/di water as it has been stripped of 99.9% of all minerals and solids and in the human body it will soon leach these minerals and such from you.

If it's like mine (and it looks like it is), this is compatible with MOST water filter systems, quite easily. That includes most RO (reverse osmosis) systems. I called the company before ordering and asked them, and would suggest you call this company too, to make sure.

As a ceramic filter, it filters out most but not all minerals, but not ions. My water starts off hard (a lot of dissolved calcium) and ends up hard. RO removes everything, but is much more wasteful of water. (every quart of water wastes a quart). If you have high levels of arsenic in your water, than RO is better. Otherwise, the choice is yours.

Recommended flow rate ca. 20 - 30 gal/hr (75 - 115 l/hr). Too much flow can grind PhosBan.
