[AntoMelta]

Nice Video That You Share , So Very Nice Thanks You This is part 1 of a 2 part series on how you can configure a working whole-house RO system.

[bundawartini]

Your Video Is Very Useful Sharing This is part 1 of a 2 part series on how you can configure a working whole-house RO system.

[bcandatree]

Hello. I started watching some of your videos and what started as a way to learn how to modify my RO system has now become an ambition to be more like you.

My question is the rotating valve that leaks out the brine and maintains the pressure within the brine part. Could that simply be a valve that is open just a small amount or is that a special rotating valve as you described?

[McillemsRemixes]

so sodium fluoride is not remove?

[SkyDaves]

thanks for the video, just made my project much easier!

[TheQuadBs]

[Number1Techguru]

@ridel149 does it remove all chemicals?

[rldel149]

@Number1Techguru - I don't think so. "All" is a very bis word. Water and some gas molecules fit through the membrane so no. It is good with big stuff like salt, calcium, etc.

[Magicbrushmurals]

Hi, I changed my flush valve recently and my water flow from faucet got low I have 9 psi air pressure in the tank what should I do to get again good water flow form faucet?

[cabadejo]

Hi there. In the UK these systems are used to purify tap water in window cleaning systems. Do you have any figures on how much a booster pump will increase production? Clearly it depends on the psi of mains water but if you were to increase the psi of water on the delivery side from 30 to 40 psi with a booster pump this will boost the production by X percent. Do you have any references you know of?

[rldel149]

@cabadejo - I don't but wherever you source the membrane should have a pressure-volume chart. If they don't (retailer), the manufacturer should. Then it is is a game of differential INs and OUTs. A close approximation can be done with averages.

[Quy4life]

hi, i have the RO system installed for over two years and recently i turned on my faucet, the filtered water came out blue/violet. Does that mean i need to replace my RO membrane or the cartridges down to the filters?

[rldel149]

@Quy4life I don't know. Two years is a long time. No way to know how many gallons processed. No idea about color. It couldn't hurt. Lines may need changing. May be infected with an organism. I don't know.

[oomblikkies]

@Quy4life Just a guess - blue colored water may indicate copper corrosion somewhere in the system.

[LuVlAzUr]

thank you for this video :) it's very useful ;)

[SuperKare123]

Thanks=)

[AHillLuke]

this is great

[f0xstrike]

Hi, what is your opinion on this RO system that claims to provide re-mineralized water, and therefore a higher PH, I can't put the link in here, but it's from a company called Santevia (santevia dot com) Santevia Enhanced pH R.O. Water System

You seem to be very knowledgeable on this subject, and your view on this system would be greatly appreciated!!

[rldel149]

@f0xstrike _ it isn't unusual to add calcium back in big operations, it is just another stage. You can see it in some bottled water labels. RO water can be aggressive attempting to reach its natural state of being.

[serch142]

I have a question how many gallons of water are going to be wasted in order to get one gallon of filtered clean water?

[rldel149]

@serch142 - water is never wasted. It recycles. It isn't like we need to take a chemical solvent to remove a heavy metal and yield an aqueous solution full of carcinogens. Yes, the brine goes down the drain. Mine waters the lawn via the field lines. Even then, it is a relatively small amount.

A more meaningful question isn't how much water is "wasted" to make pure drinking water but how much toxic waste and land-fill is produced making bottled water -or - how many gals are wasted washing cars?

[vlvl21]

what is the membrane made of???

[mrumman1978]

nice

[PalJoey1957]

1) Interesting to learn that chlorine destroys the RO membrane. Does the same thing hold true for chloramine, whch is the form most urban areas are using these days. 2) does activated carbon really remove all chlorine or chloramine? Aquarists use a neutralizing chemical for this purpose. The small amount represented in your graphic doesn't seem sufficient to do an efficient job, or to last too long.

[mrumman1978]

thx a lot... nice :)

[jcs1492]

Can you have two storage tanks (small 4.8gal) instead of a large one ?

[rldel149]

@jcs1492 - I don't see why not.

[rainbowsalads]

hi i am looking to buy a 5 stage RO unit and am wondering why the 5th stage filter is a carbon filter ,when the 4th filter before it should have removed all contaminants ?

anyone have an ideas why?

[burchified]

What about fluoride and prescription medication residue present in city water supplies?

[maioca17]

does anyone know if it will remove fluoride ?

[rldel149]

RO can leave gasses, distillation can be rather inexact since not every molecule in the steam is exactly 213 deg F so sometimes both can drag miniscule amounts of contaminants. Distallation can only go so far depending on what you are separating - i.e. PGA (5% remaining). Rain, on the other hand, is dirty when it falls (i.e. hail seeds, washing pollen, acid rain, etc.) - jmo

[dafranx]

Do you know that Distilled water is cleaner than Ionized water, Reverse Osmosis water, and other filtered waters. Water Distillation mimics the process of precipitation(raining), it purifies the water by evaporation, condensation, and ultimately precipitation. Am I right or wrong?

[dafranx]

Water cannot provide minerals to the human body; only food can give food minerals. Am I right or wrong?

Water is the universal solvent. Am I right or wrong?

[anthonyfoodie]

Great video. Wish I saw this before Itried to install my own. It helps to have a basic understanding.

[321ozzy]

Thank you very much for your clear explanation.

One question regarding the distilled water, I have heard and read here that it absorbes the minerals from your body.

Could you please explain why this is not true or not harmful to your body?

Thank you for your time,

Regards from Mexico

[rldel149]

I don't believe there is any basis in fact in that opinion. Left alone for long periods of time, deminerailzed water in copper or iron pipe, for example can be a bit aggressive but to suggest the same effect exist from human bones when the water would have to bypass the digestive system, the tissues therein and seek-out the bones seems quite silly.

Demineralized water is sold when made by distillation and RO in drink bottles - think, have you ever seen a warning label?

[321ozzy]

@rldel149

Thank you for your quick response, honestly I haven't noticed a warning label.

Regards from Mexico

[prolodyne]

Very informative video, thanks. I don't understand how pressure is maintained at the taps though surely the brine-driven pump cannot maintain the flowrate you demonstrate in the later video? Does the big gray tank contain a rubber diaphram or something to maintain system pressure? Thanks for any further info.

[rldel149]

The pressurized tank & pipe diameters provide the flow rate. Assuming the piping doesn't change, to increase flow you must increase pressure (which it does) - the moving brine provides the work. The brine pump is a slave to system pressure whether boosted or not

If water is drawn-down faster than it is made for long enough, it will deplete the storage (usable water) w/in the tank. Water will remain but there won't be any air pressure to push it out (i.e the diaphragm or bladder tank function).

[prolodyne]

Ah I see, thank you

[pkingflow1]

Reverse osmosis is bad, is leaches minerals from your body, can give you brittle bones, osteoporosis, we should drink a slightly alkaline water, take alot of supplements if you do drink it, o and floride is put there to kill you and make you dumb, hitler did it too, type in Plastic coffins in you tube, endgame, zeitgeist

[IanToronto]

Thank you for explaining things so well!

[GODSWORKMAN]

You can always change the membrane to a 100 gpd if you are using more water than that you need a commercial system.Filmtec is one of the best membranes. The temperature of the water makes a difference as well. You need about 40 psi to make RO water. We had a gentlemen that had methane,hydrogen sulfate ,iron and only God knows what else in his water.Through an extra pump, a tank making micro bubbles, and peroxide, we were able to eliminate the H S. Other tanks were used to make his H2O perfect :)

[fearmenot22890]

problem with filmtec is they make the gaskets to big, so its a pain to install membranes on a unit

[True2TheBlueYoViGang]

I commend u sir for making this video.. it may be a little boring but it is fun to know. In fact did all of u know that astrounuaghts drink theyre urine? First they reverse osmosis it then drink. Interesting this proces can clean pee and salt water and make it drinkable isn't it? Something to think about next time u have to let ur cow out of the barn. :D

I only buy RO drinking water the tap is horrid im not comforatble drinking flouride and stuff that just doesnt belong there.

5 stars :)

[fastenough111]

does it filter out fluoride? if so how can we get this?

[rldel149]

It filters out partials not gases so it would depend on the form of the "flouride".

[thelamb777]

He's obviously speaking about the form of flouride that is contained within 66% of the United States' water supply...Solid form I suppose...And frankly, all I care about is the flouride being extracted out, that's probably the most desecrating heavy metal additive in our water supply as for the current moment (speaking for 66% of us)...

[rldel149]

When I was a child growing up I recall my toothpaste had stannous (tin) fluoride. Now it contains sodium fluoride. I don't know where this "66%" statistic comes from nor do I wish to contribute to debate but when I worked at a utility district, we injected hydrofluoric acid (the same stuff people use to etch/frost drinking glasses) into the supply as the source of fluorine. I don't know much, but I think it wise to know specifically what form is in debate.

[rldel149]

Clicking on some of these search links can mislead people. For as good as the Internet is at providing information, some accurate & true, some true in context but misleading out of context & other outright false, it is up to the consumer to filter through it (no RO pun intended).

Back to the original point, each membrane has a rating based not only one differential pressures & yield but on rejection/size.

I see a lot of DOW Chemical Filmtec membrane material being used to produce cartridges

[rldel149]

I am not belittling the worry or concern anyone may have for literally God only knows what is floating in most public water supplies nor am I skirting the original question. RO membranes are very good a rejecting so many large contaminants but they do not reject everything.

Distillation is another process that removes/separates water but it is expensive and quite the energy hog.

[True2TheBlueYoViGang]

no sir don't ever recommend distilled water..that is poisonus if dranken to much it messes with something in ur body(look it up). I think it messes with the sodium in ur body? I could be wrong but its unfit for drinking

Distilled water is specially made for machinery becuase it wont clog mechanisims and other things cuz when it evaporates or something it wont leave little particles that build up...

REMEMBER THAT

DISTILLED IS ONLY AND ONLY FOR USE WITHIN MACHINES never drink that EVER...

[rldel149]

With respects, there is nothing wrong with drinking distilled water. Nothing at all.

However, I will respect your choice to avoid it if you choose and a personal choice for one of the boundaries of your own value system.

Randal

[lio0nheart]

i like this idea too much

but Ro compairing to MSF is nothing

[rldel149]

What do you mean by "MSF"?

[lio0nheart]

msf is very famous in desal world

it means multi stage flashing plant

[rldel149]

The concentrations to be removed in desalination (like onboard Naval vessels) are so significantly high multistaging is necessary.

Desalination of low levels of contaminants in water sources qualifying as "fresh water" or even "brackish" are still effectively desalinated. RO systems can desalinate quite effectively without over complicating the issue.

You don't generally need a shotgun to kill a fly right? But use one where appropriate.

[lio0nheart]

dont forget

Ro consumes power while msf produces power

the concentration of salt in Ro is high comparing to msf

[Sparkydrums]

I have a question, my faucet air gap hole is leaking water. Is it because my return line is clogged? And how long can these unit's last? Thank's.

[rldel149]

It is hard to say but an air gap is to a drain and what you are draining is brine (i.e. water off the membrane with concentrated minerals). It seems possible the little drain has gunked up on you (maybe).

Lasting... depends on the GPD rating to start with and how mineral-ed up your source is. What happens on a microscopic scale is it plugs up just like your air filter in the car or house. Your GPD will drop. When it quits keeping up with your demand - replace it.

[log6778]

COOL! I want one! :)

Nice video.

[krozzie303]

I admire the technical aspects. You are very informative and have given a great outlook on the concepts of Reverse Osmosis.

Recommended video on the subject

[rldel149]

Thank you. Many places in the word don't have fresh water. RO systems can't handle all hazards such as radon gas but they are often effective with many others.

[jws54]

could this be done with no electricity as in the high side could be loaded from a water tank and create a self running unit drivn by water power only fed by gravity?

[rldel149]

yes. In fact there are mechanical shut-off available to control the thing when satisfied.

The system is differential pressure driven. In this example, small electric pump was used to elevate the pressure (creating a larger delta-P) but as long as the necessary pressure difference exists across the membrane, it will produce water. The greater the difference, the greater the production.

[thestar13]

Nice video, I had a quick question about what you use for your animation in your videos, is it microsoft paint or do you have a special software

[rldel149]

An old version of Adobe Photoshop 4 that came with a Microtec scanner about 15-16 years ago.

[rldel149]

I have shot part 2 (inside the house and it is definitely home made). Membranes are commercially available. It is too long for one shot, probably boring to most folks and I just have not rendered/uploaded it yet.

[Bballjamal]

Very informative! Any idea on any specifics of the membrane availible? I'm th sinking since they have to be some small you must use some type of laser procedure for a diameter in the thousandths. Really looking to see if it is at all possible to do this homemade.
