Powdered coconut shell charcoal have to adhere to artificial sponge to make air filter
Newbie here. I found this thing at my local thrift shop. I have no idea what this thing is. It looks like a water purifier, water distiller, or an ionizer but I don't know. There are no brand names on it, except a meyco grommet and a voss band clamp. It has two lights that go in the stainless steel globe that is attached to the main pot. There is a connector that attaches to a faucet. It is very strange. If anyone has any information, it would really be helpful. Thanks. Joshua

I am setting up a factory for making vacuum-formed acrylic shower bases reinforced with fiberglass. I will be dealing with resin fumes, microscopic glass fibers (from cutting and handling the fiberglass batts) and larger dust particles of acrylic, fiberglass and cured resin from cutting off the bottoms of these units. I am in China, and the factoryies I have seen merely have fans and blow the stuff outside, with some directing the dusty air over a bit of water that supposedly collects the dust. Being from Canada I cannot accept such a poor solution, but my newly hired employee seems to think that the concept is best. I will be looking into cyclone systems, of which a few posts are made on this site, but can anyone post a fairly simple instructable on how to make a water based system for collecting the dust?

I found this site while searching for an answer to my question. I read the instructions; I then asked for the PDF copy for future reference. I was asked to sign in, along with other questions. I requested the free membership for now, since I do not know this site. I was then told that I could not have the PDF without paying for membership. Respectfully, I feel that it would be much better to state any rules/requirements before asking for personal information. If you do not wish to share a PDF, that is fine; just make it clear. Perhaps this is a wonderful, informative site; I may never know. Right now, I am a bit disappointed with my experience here.

Hi, I am a flood relief volunteer based in India. During flood, many children get seriously sick due to consumption of contaminated water. The flood water is contaminated with suspended particles,rotting organic matter& pathogens( specially E-coli) . These people do not have access to electricity,sanitation & medical relief. I am working on small, cheap & effective water filters that can be made/assembled at the site. If someone can suggest methods to make effective turbid water filters using commonly available materials, or send me the links which can help make these filters, it will be a big big help.

Hi, I have been looking into cleaning my well water at the source, rather than fed in into the lines. I have looked at making a simple ozone generator by purchasing one online and using a compressor to get it down 40 ft. Then I came across "silver bullet" and what intrigued me was that they produced hydrogen peroxide, which apparently is a a better bacteria killer, perhaps more stable. The reason that I want to kill bacteria and have it in the well at the source is because lots of iron bacteria and iron in my water plugging up my pump every so often is frustrating. This product looks promising, but costly, so researching this I found that they were using UV light, but normally UV light makes ozone with air. Then I dug deeper and then found out they are using a matrix made up of something similar to Titanium Dioxide (there are different forms, such as anatase and rutile which maybe more effective) so that when struck by proper UV light, it gives of an electron which will hit water vapor in air and split up water molecules to form OH- and H2O2 and some O3. So, one can buy TiO2 online, put it into a container that fits a UV lamp inside and blow compressed air through that and down the well, but the powder might get blown down the pipe. So how can one crystalize it around a cylindrical form that fits around a UV light to make it more efficient? I saw a similar post by Ian and he wants to use it for air cleaning, but gluing doesn't appeal to me as the glue itself might react with oxidants produced and give off other contaminants that I do not want in the water. So, can I use a type of glue that is safe around oxidants? Is TiO2 able to crystallize easily? ( I read that it doesn't dissolve in water well, which would rule out supersaturating water and crystallizing it that way) Any thoughts and suggestions?

Hello all~! An Idea just flew in my mind! Has anyone used or thought of using a Car air filter for home use? my primitive plan says a Car filter (My car's looks like a tunnel/Chimney) with a high CFM computer Fan mounted on top. The fan would be driven on 12v Adapter (or 9v for silence and life) and would suck air through the filter. The dust would then stick to the outside surfaces of the filter, which can be brushed off / Vacumed later. Any Pros/ Cons/ Ideas? Jump in! People!

My early experiments with oil-cooling my PC lead to some chemical *discoveries* The first was mineral oil will dissolve latex rubber. I was using surgical tubing to pump the oil to the radiator and after a day the tubes had softened and swollen so much they wouldn't stay attached to the pump. That and the oil turned an ugly yellow. (* the second was warm oil reacts with PVC, and causes the insulation on usb cables to become brittle) I'm working on the next gen of the project and I'd like to clean up the oil, but I can't quite google my way to a solution. I have filtered the oil (removed all the bugs) though a coffee filter, and a couple of paint filters, I don't have any reason to believe the rubber is suspended and filterable, but I could be wrong. Any chemists out there know what I can do?
Question by Malkaris | last reply
I recently made a quite disturbing discover and thought I share it here so other are aware of it. We all love to protect ourself in case of a fire and the first and most vital of the information chain is a working smoke detector. In my house I had the old type installed, based on a radioactive isotope that detect smoke through ionisation. The newer types working optical or using combined optical and isonisation detection should perform better - but does not really matter for this "warning". If you do have pets, smoke in the house or just do a lot of cooking you might also use one of these fancy air purifiers that use Ozone to clean the air in your room. I only have a tiny unit for a fish tank that I also use to remove smells from my work clothes or purify some water for the plants. My discovery started with a simple cooking exercise involving a lot of onions, garlic and a big wok. To avoid filling the house for days with the smells I had the ozone generator running as well. At some stage I noticed that the whole kitchen was covered in the fumes from the cooking, nicely visible from the hallway - like fog. To my surprise the smoke detector did not the usual alarm but performed fine with the test button. So I blew some cigarette smoke directly at it - still no reaction. Next day I started to investigate and was prepared to buy a new detector but whatever I used, smoke, steam or just killing a burning candle underneath cause the alarm to go off. Then it hit me: The ozone! A quick test with the hose of the ozone generator next to the smoke detector and no matter what I blew in it the device staed silent. Ozone is ionized oxygen, the detector uses the ionized particels from the radioactive material to detect smoke. Smoke or very fine dust / steam will bind the ionized particles forcing the electronics to sound an alarm because the sensor no longer detects the ionized particles. With enough ozone entering the detector there will be always enough ionization to prevent the alarm. Conclusion: If you do use ozone in your house upgrade your smoke detector to a model that uses optical AND ionisation detection! Otherwise there is a good chance that the device is unable to detect a fire. Of course chance are slim that you would use the ozone while sleeping and a fire starts, but if it does....

Does anyone know how to repair an air purifier that has been damaged by a power surge? I have several Cleanaire D2000 units - which are absolutely outstanding, BUT which have a weakness of being particularly susceptible to power surges. Since they cost $400 apiece, it makes for a pretty costly power surge. Are these kind of things repairable, and if so, where would I (or my technically-gifted friend) start? I'd like to see if it's possible to repair one of these before going out and buying a replacement. (Then the next step is to buy a good surge protector!) Thanks!

I noticed there is no usuable Intructable that I could find for a homemade Ozone generator. Ozone can be used for many things - if used correctly. Commercial Air - Water Pruifiers use it, you can get rid of harmful pesticide and chemical residue while cleaning your salad or "clean" the air after a big party with a lot of smokers. Since the basic design and work priciple is more than easy I was wondering if there is a need for an Instructable? But with Ozone not only being of concern for the enviroment in terms of smog but also being a health risk in higher concentrations I am not so sure if it is a good idea. After all we don't want to cause any harm with our projects...

Hi all. I'm finally starting the prototype of my solar condenser this week, though this question doesn't relate to it directly, but to using it to power a steam distiller to purify water. How much water will ten kilowatt hours boil? ie, if I have one kilowatt of solar energy coming in over ten hours and 100% of it goes into heating the water. Also, for extra credit, assume the water is in a black plastic container also in the sun, so the water is preheated to whatever temperature that would be likely to heat it to. cheers!

I am intersted in purifying water through freezing. I know when you make ice cubes, the white cloudy stuff/minerals/solids gets frozen in the center and therefore is the last thing to thaw out back to liquid. I was wondering if that would be about what snow would do, or would it have to be a solid block of ice for that to work? I don't have a dissolved solids meter or I would test it myself. I'm pretty sure snow is fairly pure to start with, but I could be mistaken. It does have a taste to it. What is that taste?

Having seen mythbusters, i am curious how the stuff is made. during my internet searches, it is made by heating ammonium nitrate to ~250C. from watching the episode, i know there is more to it than just that. I am under the influence that everything else that was done was purifying the stuff. i am mainly curious about how this is done and whether or not the stuff is toxic, dangerous, addictive, or anything else of the sort that would make it bad to breathe. I will be honest, if the stuff is not dangerous, i will slowly and carefully attempt to make the stuff and maybe breathe a little of it in the curiosity of what it does. for those who don't know, nitrous oxide is also called "laughing gas."
Question by seansippo | last reply
I am interested in building an Atmospheric Water Generator, a machine that creates water from nearby air, kind of the what happens when window air conditioning units drip water, but at a much higher scale. My goal is to create a unit capable of producing 1-2 gallons per day, for use here in southern California. I've read https://www.instructables.com/id/DIY-Atmospheric-Water-Generator/, a great write-up. Mostly, it requires a dehumidifier, with a stainless steel element, a water filter and tubing. I am wondering if I use a non-stainless steel dehumidifier, about 1/4 the price, and a really good water purifier, if that'll do the job. Also wondering if the dehumidifier will get mineral or other kind of deposits and need to be cleaned periodically. Anyone have any insights on this? Thanks

I have a nice little 120VAC to 7.5KV transformer that used to call an air purifier its home, but I'm not sure how to wire it. I have some guesses, but I want to make sure I don't burn down my house so I am hoping to verify them with the help of the instructables community. Here they are:The black and white wires are where you connect the source of 120VACThe green and red wires are the high voltage outputs. (I'm guessing that since this was meant to be a negative ion generator, the green was just connected to ground)You can just connect this to a power outlet and have it run WITHOUT burning down the houseI am not sure if you need a fuse, though.Note : The transformer looks like http://www.goldmine-elec-products.com/images/G1783B.jpg except it also has a green wire.

I am quite interested in the articulation of the bones of animals. I plan on using small game (squirrels, frogs) to begin with, and I will probably donate them to my Biology teacher, since she loves skeletons.The process of defleshing and whitening the bones of the animal is fairly straight forward - soak the carcass/skeleton in chemical baths and take it out when it's done. The chemicals needed for the process are what's going to be hard for me to obtain.I need a 0.3% solution of sodium carbonate. Sodium bicarb is extremely easy to come by, but I've never seen sodium carbonate. I've heard it is used to raise the pH in pools, so I'm guessing a pool store would carry it. But, would it be possible (practical) to make it? Is there a way, using household chemicals, to produce sodium carbonate? I don't need very much.Secondly, I need a 20% solution of hydrogen peroxide. I only have a 3% bottle. I've heard H2O2 is some pretty dangerous stuff. Again, is it possible for me to buy/make it? Would freeze-purifying it work?Thanks for any help, and if I get this to work out, of course it'll all be turned into an Instructable.

Ok, so a few of these questions may be really simple, but I have very little experience in these categories. 1) I'm working on a small camp stove that apparently is supposed to run on meths. I don't have access to meths and cannot buy any. Will Rubbing Alcohol work as a substitute? The plans for the stove seem to say that the vapors are what are on fire; it doesn't soak up through a cotton wick. 2) Will Canola oil vaporize so I could use it for the stove mentioned in question 1? 3) Phosphorus is a key ingredient in glow/light sticks. I saw a tutorial (which, by the way, would make a good Instructable) that showed how to obtain it from strike-anywhere matches and use it to make a custom glowstick. Again, I don't have any strike-anywhere matches, and I can't seem to find anywhere near me that sells them, so: Is there any other any household items that contains phosphorus that I could extract? 4) Is aluminum the cheapest metal, as in scrap metal or non-shape-specific pieces? Edit: 5) I have 70% rubbing (Isopropyl) alcohol. Is there anyway to purify it to around 90%? Thanks!

As the "expert" of my project, we might exchange ideas and offer suggestions to improve the project, and even maybe advice on the best ways to manufacture the final prototype for assessment. You can be as involved as you want to be honest, I appreciate that everyone is busy so you won't be able to commit a huge amount of time to this, but maybe exchanging emails around once a month? I might send over some sketches / cad files over email for you to evaluate and suggest some improvements or ideas on, nothing more than that.If you're willing to help, please answer this topic so we can work something out!
