Reverse Osmosis for Car Wash

Please help me determine whether or not this unit will suit my purpose of washing vehicles.I plan to attatch the unit in my garage at the water source connected to the hose.The hose will be connected to a pressure washer which uses about 2 gallons per mintue.

Will this unit cut it?

Also, can it filter out the sediments to ultimately leave a spot free drying finish?

Please set me up with a proper unit for my application.

A. You want to wash vehicles with reverse osmosis purified water. Hmm… I don’t understand why that’s needed. RO water is usually used for drinking, bathing, or food processing industries. I think vehicles can do without this expensive method.

B. A 50 gpd (gallons per DAY) system, can not be used for a 2 gpm (gallons per MINUTE) source.

There are commercial RO units available that can be used for heavy usage, however those are far more expensive then standard home reverse osmosis units.

There’s no sediment left behind RO processed water.

I understand the purpose of a 50 gallon unit. It would in fact suit me as I am low volume. I’d be washing 1 to 2 cars per day. That’s it. So I figured at 2 gallons a minute x 15 minutes MAX to finish a vehicle I’d only use about 30 – 40 gallons. And still have some to spare. What do you think? Honestly, would this unit work if I used it as such? I am pretty much out of options as the local stores only carry a 10 gpd system that is useless.
Please explain to me why the system only give 50 gpd? How does it store 50 gallons??? I guess a concern on my mind would be the flow rate of this particular unit. I mean, can I depend on the water being readily available for washing. Of course I realize the RO water expires after 50 gallons.

The 50 gpd unit comes with a 3 – 4 gallon tank…

It’s more the capacity of the reverse osmosis tank that you need, not the system production rate.

There’s a large tank, a RO-Mate tank, 80.0 Gallons, (this is reduced by air that’s needed for pressure), 24″ W x 57″ H. (one size smaller is 40 gallons)

What’s on your mind
