Reverse Osmosis 2A, Subpart b - Whole House Adaptation

This is the second part (made itself of 2 parts subpart a and b) on reverse osmosis. The fist part in the series covers theory and the system components that are actually shown in part 2. They are shown but not discussed in detail. The system isnt very professional in appearance mainly because it started out as a simple concept of building a CPVC dedicated piping system into the house as it was being built to serve each vanity in the house, the kitchen sink and refrigerator. The concept was to be driven by a conventional 3-stage under-sink RO system with a much larger storage tank. The only additional original modification was to add a large whole-house carbon filter for additional finishing. The system worked but at lower than satisfactory volumes therefor a low-volume/high-pressure diaphragm pump was added. This improved production but ice cubes were still smaller and tea jugs and coffee pots took longer to fill than we liked so a permeate pump was added. Finally, after a number of years the under-sink 3-stage unit failed and was replaced with a simple 75 GPD membrane and housing.

Easiest way to ID a pump to operate on discharge side of RO?

Also my manufacture suggest cleaning (flush Chlorine through system) bi annually. Do U go through that trouble twice a yr?

[rldel149]

@cheerdiver - no about once every 3 years. I should do it more often, just don't.

[cheerdiver]

@rldel149 About the 1st question that was not addressed, The water motor on the discarge (brin drain), to decrease RO side of membrane pressure and increase RO discharge pressure.

Would U please give an example of what to look for when procuring that part (pump).

@cheerdiver "...Would U please give an example of what to look for when procuring that part (pump)." -- yea, google the name permeate pump, I'm sure it will work out from there. Pictures, part no.s, something will pop up and look familiar.

good luck

wtf is this for ? lol

[rldel149]

@JahSmokebuds "wtf is this for ? lol" - for removing high levels of calcium carbonate, trace iron, salts and other things from water pulled from a ground water supply (i.e. a well). Enjoy a kidney stone or two during the summer months of clean lime scale out of coffee makers, irons, etc. and you will get the idea.

@Glen1040 - thanks. My beloved is picky about water.

@JahSmokebuds If you live in the city, this system would also remove the deadly sodium fluoride that's added to over 70% of the nations municipal water supplies. Do a YouTube search for "fluoride" and you'll get the idea.

A lot of useful information there, thanks.

yeah
