Reverse osmosis filtered water
    #23996938 - 01/09/17 11:14 PM (7 years, 21 days ago)

Hey so i couldn't decide exactly where to post this, but decided here because one of the uses of my RO filter is for water for my plants. I recently purchased my RO filter to try and use for my self (garden of the mind) as well as some of my plants, i just got a kratom cutting and decided i want to be more conscious of the water that i give it, and it sucks trying to go organic veggies outside and using the city water. I know they put all sorts of chemicals in the city water, the main one being fluoride and ive been trying to take steps to reduce my fluoride consumption.
  The shitty part about my filter is how much water it sends through the waste water.Ive figured that its 10-15 gallons of water "wasted" per gallon of drinkable.I know that using the ro filter means there is going to be alot of waste water but everything ive read online says it should usually be around 3-5 gallons, not double or triple that.
  I live in California and we are also experiencing a historic drought and I want to also do my part to help conserve water whenever possible. It just sucks because i love the RO water, I drink it and I genuinely feel like im giving my body exactly what it needs and not poisoning myself. It wastes so much water that lately ive only been using it on special occasions like once a week. 
  I have been trying to figure out some other uses for the waste water or any other solutions to have my waste be a little less. You dont realize how much water you use on a regular basis until you start to try to cut out fluoride. I just thought i would post and try to get some other peoples input on possible solutions for my problem, and maybe hear some other peoples experiences with using RO filters as well.

I hope you're not drinking RO water straight out of the filter. That thing will cause all sort of troubles for you, your body is not designed to ingest water without mineral content.

I have no idea what you can do with the waste from the filter. If you assume (more or less correctly, in my opinion) that water from the tap is not very good because of what's dissolved in it, what can be said about water that has had its concentration of nasty stuff increased by removing H2O out of it? You would probably be better off drinking bottled water...

I'm pretty sure that's not true??? Also water is meant to be used to clear the body of toxins... and not to provide minerals and nutrients.

It's not simply about what it's "meant to do" or not. Water dissolves minerals and salts and in our body is present in a certain proportion of water: minerals.

You can get too much or too little minerals by consuming either hypertonic (too mineral-rich / salty) or hypotonic (too little minerals / salts) water respectively. The latter would be the case when you ingest demineralized water, but it becomes a problem only when you ingest enough of it or keep it up over time. You have to ingest those minerals and salts in your food to compensate for washing them out with pure water!
But, the minerals have to be bioavailable: they have to dissolve properly and be easily absorbed by the body, otherwise you just poop out most of it as is the case with something like magnesium in the oxide salt form.
That's the difference between cheap and expensive vitamin pills by the way: the cheap ones you tend to not be able to absorb so they are useless even if they contain what you need.

Since I live in the netherlands which has tier 1 tap water, I probably wouldn't know, but part of the fluoride fears seem to be based on pretty vague ideas which have nothing to do with the actual toxic levels in some tap AND natural waters which cause nausea and diarrhoea etc. I am talking about people who believe that fluoride is added to keep the people mentally subdued somehow. Probably calcinated pineal glands are mentioned as argument? Which by the way do get calcinated when you grow older, from calcium fluoride mineralization but this is not dependent at all on how much fluoride you consume.

If the tap water is safe to ingest (which I hope it is 'by definition' where you live, on the level of pathogens), then the only thing filtering may do is deprive you of minerals which you can compensate for. No idea what you would ingest if you drink water that contains a concentrated form of anything dissolved in your tap water, but that would be an easy way to exceed safety levels because of the concentration performed.

We use a R/O filter, without it I spend too much time decalcifying my pots, it depends on your local water, if our water was better I'd probably not R/O. 

Some plants are sensitive to high salt levels and you can tell by the leaf tips if theyre suffering or not. Most dont need R/O water, tap will suffice.

R/O is quite wasteful and the reject water is rather nasty, dont use it on any plants.  In some places R/O is illegal because the reject water poisons waterways like creeks and ponds.

Sorry for double post, thought i was editing the old post




The cities water is full of flouride, which is a chemical that is a waste byproduct of aluminum production there is nothing natural about it and studies have shown that it does in fact have a negative impact on brain delevopment. Not to mention the history of it first being used in the ocncentration camps by the nazis on their prisoners, it wasnt untill 1946 (not coincidentally one year after WW2 ended) that they started putting fluoride in the water after they started bringing the nazi scientists over to help with social engineering and other projects ( operation paperclip)  ,  there are also many other heavy metals and other chemicals that are in the water as well, my house is over 60 years old and i live in a big city that who knows how old some of the pipes are, and its been an issue that people in my area have had teeth rot as a result of the water.
http://www.latimes.com/local/california/la-me-gardena-dirty-water-20160314-story.html
this article is about a place only a couple towns over, but we really are all just a part of the greater los Angeles area so if the town 5  miles over is having problems with their water then im going to be skeptical of my own as well.
Choosing to drink bottled water has nothing to do with being gullible. I test my water, and my tap water alone has between 400-500 parts per million at any given time and after i run it through the RO filter it brings is down to 20-30 ppm and actually tastes like water, its some of the best water ive had besides spring water from mount shasta.

Toxicity is not so much about harm potentials like these as it is about the concentrations, or to be precise the two factors combined.
So of course, it's different if you live in an area where they somehow exceed safe limits.
A question is how ubiquitous actually toxic concentrations are.

R/O water is ok to drink, dont drink distilled water or deionized water.

To the OP:

If you are really looking to conserve water, consider a Permeate Pump.  It's actually a good idea in any RO system.  Few spend the extra money but makes your system work better.

As to your plants, RO provides a "clean slate" with which to add nutrients.  It allows one to control what you put into the water, to add nutrients that will reproduce pH routinely, and provide the plants with less solids but the ones they need versus who knows what.  Likely way too much calcium and other hardness/alkalinity issues.  Much of the hard water is highly alkaline, you gotta get that shit out of there.  Adding acids in this case doesn't work, in fact it just makes a bad situation hard to control.

As to the rest of the discussion relative to what a person should or shouldn't be drinking, my advice would be to use the RO and add the best salt you can.  One example is pink himalayan.  I like a variety of salts but in general would recommend an old sea mined salt versus a current sea salt.

I'm pretty good at systems if you have any questions.  I'm the guy that tells the factory what will work better then they ignore me out of their ignorance, but it's all good!  You may have a reversed shut off valve connection, for sure.  You will have much more waste.  Does your shut off valve chatter?  What's your incoming water pressure?  Are you using a reducer in your drain line currently?  You need to, other wise once again massive waste.

Your water is likely very hard which means more waste.

The question should be why are governments mass medicating people based on shitty 70 year old "science"?

Concentrations "safe" for some adults aren't safe for infants, children, and other adults. Fluoride is one of the hardest things to remove from water via filtration.

Water is called the universal solvent, can dissolve and wash-away good substances, as well as bad ones.

In practice, though, you would receive the same minerals, from other sources.

I believe the drought is as fictional as your need for fluoridation, that fluoride is probably an anti-nutrient, and those notorious experiments were upon malnourished people.

The Dervaes family has apparently used rainwater, to grow tons of food, on a small allotment, but we can also speculate as to whether the rain was contaminated.

There are countless sources of water, besides the plumbing, and ways of purifying it, besides osmosis.

Don't mean to hijack the thread! Quick question. Is RO water ok to use for mixing my substrate? Or is distilled better? I just have access to unlimited RO. Not sure how it would affect the growth.
