Possible use of RO/DI waste water

Based on what your city's adding into the water, it could grow your grass faster. at least my city adds minerals that help grow plants, so when you make rodi water, the waste just has a higher concentration, and itll be even better.
 
Ours goes into our swimming pool and pond or 1 gal containers for watering the plants in the summer.
 
I pour mine onto my lawn and my neighbour doesn't.. .. but his grass is greener lol
Can you use the water water to fresh water dip corals and rocks rather than using tap water or good rodi?
 
Don't freshwater dip anything, imho. Use CoralRX in salt water for corals. And quarantine and TTM your fish (see note atop forum).

The wastewater contains all the things you don't want your critters to be breathing, for one thing.

You can water your lawn with it or wash clothes with it, or any ordinary utility use of water. It's just got a concentration of minerals taken from the water that was stripped down to ro/di.
 
That stuff makes perfect plant water for garden or houseplant, I use it for that and, because phosphates are my main problem, it feeds my plants nicely.
 
I specialize in African cichlids. The African Rift lakes are high in dissolved solids, hard and alkaline, and many folks add various salts to African cichlid aquaria. I always collected RO runoff in 55 gallon drums and used that for rift lake cichlids. I did not dechlorinate it, just used it straight. As an aside - many years ago I converted Hemichromis bimaculatus (Jewel cichlids, which are NOT rift cichlids) to full-on salt water. Freaked out the local LFS. Gave them to the LFS and they used them to cycle marine tanks. :lmao:
 
Does anyone know if the waste water from a RO/DI would be harmful in makeup to grass? I'm thinking of collecting in a cistern and spreading on the lawn during the hot months. Thanks for any feedback.

It surprises me how many people tend to think of the 'flush' water from an RO unit as something to be treated like a harmful chemical.

I drink my flush water, & why not.

If the water going into a RODI unit is good enough to drink, then the flush water, which has by this time gone through a sediment filter, & then a carbon filter is certainly good enough to drink.

But what about the TDS??? The TDS level will barely be higher than before it went through the membrane housing, and, those disolved minerals are what humans need to be healthy.

Just don't drink RODI treated water regularly, that's not good for you. :rollface::rollface::fun4::spin1:
 
Not to beat a dead horse, but it's pretty near impossible to give Rift Lake cichlids water which is too hard. Many cichlids actually grow faster in pure salt water. I don't know if it's still done, but many years ago Tilapia were being bred and raised in the ocean; they grew faster and larger in pure salt water than fresh. I've observed black blotches on Neolamprologus brichardi (Lake Tanganyikan cichlids) which were kept in tap water. With the addition of salts these blotches disappeared. Waste water is great for Africans. I've also kept plants like Vallisneria in extremely hard water - I had to cut them back as they would reach 7 feet! Very soft water usually killed plants.

I have suggested that many time before. Why some people refer to the wast water from a RO unit is like sewer water just shows the complete lack of knowledge of how a RO unit works. The wast water from a RO unit is going to be much cleaner than the tap water coming out of the faucet since it has already gone through your prefilter/carbon filters.
 
Good to make :beer: :spin1::rollface:



talk to me


I have reasonably soft stable tap water and add tiny amounts of Gypsum, Calcium Chloride and Epsom to my tap water to create a balanced profile. I take it these would be in higher concentration in the RODI run off versus what's coming out of the faucet
