Bottled Water for Developing Film

Bringing tap water to a oil will not only eliminate oxygen but also chlorine. It will also remove temporary hardness causing any calcium bicarbonate to precipitate out as calcium carbonate. After boiling allow the solution to stand overnight and decant the clear potion for use.

Hi Bill

I do hope your drought is short term we have had long dry and wet periods here. Record hot and wet at moment, otherwise we get hose pipe bans.

I read it as the OP in the linked thread went to filtered water instead of distilled. Id not think of either drinking distilled or using it for making up D76. I've not seen distilled for decades here only deionized.

(there was a url link here which no longer exists)

And wash water need not be mineral free our WWII ASW corvettes needed to use changes of sea water with a final rinse in faucet from a bottle and when they archived them post war their negs were as good or better than negs from vessels with desalination.

Sea water is like hypo clear...

A chum (who is a member here) needs to do something on his final rinse to avoid spots, which only occured on Trix (! ) - think he filtered it. My water equally hard has particles but I don't use Trix. Im told evan the local rivers are chalk streams with specific flora and fauna.

The stuff I'm using is Norwegian spring water, so I think it's naturally low in minerals. For instance, there is little or no chalk there.

When I have some time, I'll run a more detailed comparison between fims developed in spring water and tap water.

Well, I'm not that fussy, you know.

I'll have anything with magic in it

There exist kitchen/laundry small appliances for distilling water at home. I have expensive electricity, so it's about the same price for me to get a jug for a $1 at walmart of the grocery store, so that's what I do. If electricity ($0.15/kwh) were cheaper here or water were more expensive, it'd be a good piece of gear to have.

Perhaps this is off topic, but I would love a device to catch and condense the steam from when I'm cooking. It would be economic and environmental and stop the windows steaming up... How about the water collected by a dehumidifier? Friends need one to keep their modern ultra well sealed and insulated flat turning into a steam bath on winter...

Ice inside fridge or condensate in humidifier both equivalent to distilled water but

The normal prepackaged developers are designed for very hard water anyway.

And when I make up the PQ developers from scratch and dont bother with softners in very hard water they still work to specification...

your time might be better spent searching for the edge of the universe. why not distilled water too?

Yes but is it more powerful than a speeding locomotive, faster than a bullet and is it possible to hear what's written in the same voice that used to do that gentleman's introduction. I used to walk more than 2 miles to see said programme on my auntie's TV in about 1956. We couldn't get ITV on our older set.

Power to the turtle!!

Well, with the negatives, I can check density, count the spots and check base clarity.

With regard to finding the edge of the Universe, I have no idea how to go about it.

Distilled water is necessary for mixing alt process chemicals like diluting silver nitrate for salt printing. When mixing chems that has precious metals, why chance it?

I'm not saying it's best for mixing conventional chemicals. Again, I think drinking bottled water when you live in an area with good tap water is bad for the environment and a waste of money. I've been mixing BW chemistry with Sacramento tap water for decades and never had an issue.

I'd be wary of that. While it is a sense "distilled," it may well carry particulate matter and various other "stuff" present in household air, which I've read is pretty polluted. The fins on the evaporator coil on my dehumidifier look to be aluminum, so the condensate may also contain aluminum salts.

Your post has reminded me to ask what kind of water a condensing tumble drier produces in terms of suitability for film developing and/or washing. Is it the same kind of water as produced by a dehumidifier? I have heard of the danger of particulate matter from household air but would this apply to a condenser tumble drier. Certainly the water that is produced from our tumble drier seems very clear to the naked eye.

Thanks all for answers

I have to clean my dehumidifier tank a couple of times a year as I find all sorts of unpleasant things growing in it. I'm pretty sure if I left it untouched for a while they'd develop basic language and start colonising the rest of the house. I wouldn't let the water that comes out of that near my film or paper

A pack of ID-11 or D76 is designed for hard faucet water.
HCA and faucet water is best for washing,
If you get deposits on drying try deionized soak for final rinse.
note I just increase surfactant and use a film squeegee.
You only need distilled for specials and you need to
be careful. I collect spring and filter... for c41.

What is a condensing tumble drier? Here in the USA I am familiar only with gas fired or electric clothes driers, the latter use resistance elements. I'd be curious about the efficiency and initial cost of such a drier as you mention.

Here in the U.K. we have two types of tumble clothes driers. One type vents the moisture laden hot air extracted from the clothes to the outside via a tube. Effectively it dries the clothes by heat which creates moisture laden hot air and the moisture is vented to the outside.

The second kind, the kind to which I refer, condenses the hot moisture laden air back into water and deposits the water into a tank within the drier itself so acts like a dehumidifier, except that the air is fed into the drier, heated to dry the clothes and then hot moisture laden air is condensed back into water and deposited into a tank in the drier. You empty the tank after every full wet clothes load, once they are dry.

It would appear from posts so far that posters believe the water in the tank to be no different from the water collected from the moist but only ambient-temperature air in a room and deposited in the dehumidifier's tank

They may well be right. However the water in my tumble drier tank looks to be completely clear and clean and all I am trying to establish is whether such condensed water is (a) the equivalent of de-ionised water and if so whether de-ionised water from such condensers is fit to be used as part of the developer and as part of the final rinse and is better than tap water which in my area is hard and has minerals in it

If it is clear and mine is, then I am not clear why this should be any different to de-ionised water or distilled water that you purchase.

Left in a container for several days/weeks the water may eventually grow algae and it may not be suitable to drink but as the water will be used shortly after it is collected, will not be drank and is clear then all I am trying to establish is whether chemically speaking it is either the equivalent of de-ionised or distilled water.

Thanks

Interesting. A condensing drier sounds like an expensive proposition. Sound like a standard dehumidifier, but with an extremely humid and from your post hot source. Hence my positing "expensive," both in initial cost - compressor, coils, sealed system, and in operational costs.

My caveats about dehumidifier condensate would still apply. However, YMMV.

Condensed water from any condenser, whether AC or clothes dryer, is not at all equivalent to deionized water. The mineral content may be lower than tap water, and there will be no chlorine, but such water can be expected to have metal ions, mold, particles, lint; who knows what. It may well be ok for photographic purposes but please don't pretend it's equivalent to real deionized water; I work in the semiconductor industry and the thought makes me cringe. The condensers on these devices treat the water as wastewater and no attempt is made to keep it clean. Have you looked at the junk that builds up in an A/C condenser drain?
