Reverse Osmosis Car Wash

A post from long ago, Reverse Osmosis Article June 05, comments a little about Reverse Osmosis for Car Wash.

Recently, some readers suggest we add the following lines to complete the thread.

When car washes were first introduced they used three things: soap to clean the car, water to rinse it off and towels to dry it.

Recharging Storage Tank Procedure

I have recently ordered replacement filters for my Microline T.F.C. 25S RO water filter, and still am receiving a VERY small amount of water….
Can my current tank (which is what I now suspect is the problem), be recharged, and how would I do this?
Or do I need to replace the tank?
Is the RO4B tank compatible with my MicroLine RO system?
The tank and RO system are currently under my kitchen sink.
Is it better idea to get a tank (if I need to replace it) with the replaceable bladder?
Thank you for your assistance with these questions.

Here’s the information that might be helpful.

RECHARGING STORAGE TANK PROCEDURE

PROBLEMS:

  • When you turn on the RO spigot you noticed small water pressure coming from the storage tank.
  • When you turn on the RO spigot, only a quick burst of pure water comes out of the system, and it slowly dies down to trickles.
  • When you turn on the Reverse Osmosis spigot in the morning, you only can get less than one gallon of purified water.

    3 stage reverse osmosis

    Will you please explain the difference between a counter top reverse osmosis 4 stage and 3 stage filter systems

    The four stage unit contains one more carbon filter to provide better purified water then the 3 stage Reverse Osmosis System.

    John Guest Connector

    subject: the Plactic Connector for CL1030T33B, the small one with the hexagon shaped end.
    Comments: This connects to the water.

    The Connector you described are known in the RO and/or water filters industry as John Guest.

    Here’s a link to one of the online stores that carry these.

    FASTEK Osmonics Membrane

    I’m trying to replace a filter with the following printed on the outside:
    FASTEK MEMBRANES
    MODEL TLC-18
    S1312-18S
    S/N 8436 – 8905

    The Osmonics TFM-18 (TLC-15) is same as TLC-18.
    Just a different label.

    It’s a standard size RO Membrane

    Copper Pipes for Reverse Osmosis

    I have one up question.Why does the RO water “dissolve” the copper piping?I thought that RO water was really “only” ultra filtered water (i.e. water that has passed through a permeable film leaving behind undesirables) and as such the chemical composition should not have changed.

    I can only wonder what it would do to your stomach if it “dissolves” copper!

    Thanks for your comprehensive reply.

    From Cornell University site (PDF file is here):
    The storage tank, tubing, and dispensing faucet should be made of plastic, stainless steel, or other nontoxic materials. The low pH and mineral content of RO-treated water may corrode copper pipes and allow lead to leach into the drinking water from brass components.

    RO Wastes Water

    I want to install an under counter type filter in my basement and pipe the purified water to a sink mounted spigot and my ice maker.

    I understand that the RO unit produces waste water.

    Do I have to have access to a drain to dispose of this water?

    As you’ve indicated, there needs to be access to a drain for the rejected water. Also keep in mind, that the water pressure needs to be high enough, to provide purified water at a satisfactory rate. If it’s low, a booster pump might help.

    Hope you succeed.

    Removing Salt from Water

    Reverse Osmosis can treat salty water?

    I would like to know if both the Reverse Osmosis and the Distilled Water Systems remove salt from the treated water. Has a test been conducted that I might see the results of water before treatment and after treatment? thanks.

    The answer is Yes.

    Both technologies, Reverse Osmosis and/or Water Distillation would remove the salt.
