DI water only

oh, good grief :p

No vino... but answering queries like a madman before leaving for the seminar and frag workshop at That Fish Place this weekend. I still have almost 200 unanswered queries in my personal box. Never caught up since IMAC last weekend. Grrrr :p

Sorry to seem daft, my friends. I was just answering posts obviously without reading the threads. Doh! How helpful is that?!?

I'll stop/rest/go slower now :D
 
Anthony, I couldn't see in your posts what your TDS on the input water is that you use? Wouldn't that make a big difference in how long the DI will last?

Steve
 
very true... your water will fluctuate seasonally (if not more often) in TDS and in turn has an effect on the DI terms between recharges.

My source water is moderately hard... ranging from 160ppm at best to over 200ppm
 
There are numerous free online translators (google). You could type an English inquiry and then send it to the German folks looking to buy a turnkey system.
I wonder too if they are available i the UK (seems likely). Easy then to chat with an Englishman and have one sent across the pond. Do be resourceful here my friend. The Internet is an amazing tool... google til you can't google no more

Now I'm confused. :confused: Was the above reply to me, Anthony? How did the UK get into it?

I've checked the Kent link. It's hype. I see no analysis. 99% of what contaminants? organic? microbial? ions? and what does it put into the water? How long will it last with incoming well water over 350 TDS?

When I searched for a local provider I asked and received their after treatment water analysis. None I found acceptable for my hobby.

You keep saying what great quality the DI water is Anthony but I can't find the analysis. I'd like to see: 1) the after treatment analysis; 2) what it doesn't remove; 3) its life with 350+ TDS going into it; and 4) what it sends/adds to the water when it removes the ions. Have you got links to that info?

My very hard water has silicates, sulfates, nitrates, and organics that I would be concerned about removing, in addition to the common water treatment chemicals.

I don't want to add 'reef safe' remedies and additives to my tanks that I don't know what's in them, or only by anecdotal testimonials. The same goes for the largest ingredient I use ==> water.

The real specs and facts are, I think, that which makes the move to DI determinable. Language like the Kent link uses: "purest water possible" is meaningless. I would also like to know the probability of channeling and when I know that one or both DI stages are not working, or spent without checking my water every gallon.
 
leebca,

Perhaps you may want to discuss this with Randy over in the Chem forum. He is away for a few more days but you guys can
do the "talk Chem" thing.;) I know he has written some articles on the whole RO/DI thing. Just a thought.
 
Thanks Hobster.

I don't want my post to 'sound' angry. Writing as a form of communication isn't always clear.

I'm not from Missouri but 'show me' is a fundamental part of my scientific background. :D I'll buy what analyses to be what I want.
 
Am I correct in thinking that because there is no waste water that you don't need a storage tank? I gave up the idea of RO because of all the waste water so I'm very happy to hear that DI is a good alternative. Thanks !! Does anyone know the approximate dimensions of the Deion 200-R? I would like to install it in my laundry room. Also, is there only two connections..input and output ? Thanks again Mary
 
Lee...

the UK reference was with regard for you pursuing Aquatechnics via an English distributor. The UK most likely has english speaking (ahem) dealers of this German product (a neighboring country :D). The English adore Discus fishes, other cichlids and fishes requiring soft water/DI etc.

As for mfg specs... just because they are not posted on the website does not mean they are not available to you, mate. Are you saying that Kent and Aquatechnics refused you request for the info? I'm guessing you simply mean that you have not seen it published.

Aquatechnics (on their website which you can read by a Google earch and tagging the "translate this page" link with the hit) lists Kat/Ani as being able to produce 60l/hr of demineralized water measuring 1/10th of a degree of German hardness (or less). Extremely soft and demineralized water.

As for the actual assay of this unit with your personal tap water... I'm pretty sure they did not run that trial ;)

Just e-mail them, bro and ask for the info that they do have. Or... lament about not being enabled by the mfg, us, etc :p

My mfg specs that came with my purchased units (some years ago) are buried if not lost in my filing cabinets. I regret to say that I do not have the time in the near future to dig for them. I was just hoping that you'd take me at my word enough to want to simply e-mail the mfgs and get the factual specs yourself.

You still need somewhere to hold the water. I use a large Rubbermaid Brute plastic garbage can. My Kati-Ani will comfortably make 10 gallons per hour (which beats the pants off off mpst RO units), but is too slow to not store.

I don't know how big the Kent unit is, but I would bet it is about 18" long by 12" tall by 6" wide.

All DI units only have an input and output.

OverAnalyzer,

Thanks so much for the link to Google.

As you had posted;



I just thought you might share where that was.

Fsdr posted the site

"I just ordered one for 166.99 at http://www.aquariumplants.com/cgi-bin/cart/kent914.html"

Brace yourself - this works for all kinds of products and things....

go to google - type in the exact name of the unit and hit search..... surprisingly I check this board from several locations and don't bookmark every find - just good threads.

1/2 the stuff people ask about could be answered with a little thought and 5 more minutes of their time checking other resources.....

Your "where" post is almost as bad as "just tagging along" posts. Now - if you look and can't find anything - then ask! :rolleye1:

Your sarcasm is not appreciated.

Your post was unclear and it does not make sense to write, "found it cheaper elsewhere .... $170" w/o saying where.

My 2 cents.

Thank you for the info. Another thing I like about DI only is that you don't have to worry about draining all of the waste water out of your garage. That was my main concern with the RO/DI unit being installed in my garage.

All you need to do is have a storage tank with a float valve.

I would like to know if anyone has tried to convert or its possible to convert an RO/DI unit to a DI only unit and How?

Thanks
Albert

Albert,
I am thinking of doing the same. I would imagine that you just by pass the RO membrane so the in flow of water just goes in the sediment filter, then the carbon and last the DI. I need to look at mine to trace the flow to be sure.
( I found a really great way to do it on line but I can not say where :D :lol: )
 
By the way, I still have not heard back yet from Aquatechnic. But, I expected it to be a while until I get a response because of the language barrier.
