White particles in water?

Ok, this is now driving me crazy. When I pour a glass (empty glass, no ice yet) of water (filtered, old filter) the water is clear. Pour over ice and big puffy white flakes appear. At first, I think that there must be crap in my ice. So I buy a silicone ice cube tray and use filtered water to make ice cubes. Second iteration: filtered water over filtered ice. Results: BIG FLUFFY WHITE FLAKES. So, that didn't work. My next thought was that maybe I messed up with the ice cubes. So, I switched to distilled water for the ice cubes. Third iteration: filtered water over distilled water ice cubes. Results: BIG FLUFFY WHITE FLAKES. Again I found myself with nasty debris floating in my water. What's next? Oh, maybe it's the detergent I used to wash my glasses. So, I wash a glass by hand with Dawn soap. Fourth iteration: filtered water over distilled water ice cubes. Results: you guessed it... BIG FLUFFY ****** WHITE FLAKES. Gotta say, it makes me want to pull out my hair! I just don't get it. So, here's my question: what's causing the white flakes? I read somewhere that cold temperatures can cause certain salts (not table salt) to precipitate out of solution. This can also be the case with Magnesium and Manganese. Does anyone else have a solution? I just want to drink some nice clear water. I thought for sure a Brita filter would do it for me.

Well Filter

Hi there, I need a water filter for my well, which i can hook up before the water riches the pressure tank. I got a lot sediment in the well. I was thinking of a filter like from a fish tank. My Idea is , i fill it with gravel from big to fein (Sand) gravel in at least a 6 inch pipe and about 4 feet long. The pump company ( Flotec) told me that i need a pipe with min. 100psi rating. I want use a clear pipe so i can see when i have to change (clean) the gravel.It should also be mounted in the basement ( freeze protection). I found on the i-net a clear pipe with treats on the top and bottom, but than it's not rated any more for 100 psi. so what can i do. Any clue?

can a automotive fuel filter be used to filter drinking water? Answered

I am working on an emergency water filtration system for when I go camping. This system would be used to manually filter out sediment before I purify the water. Automotive fuel filters are cheap and easy to connect to tubing, but I am afraid that the paper filter element might be coated in some sort of toxic chemical that will leech into the water as i filter it. I cannot find any information about this subject on the internet, so if you know anything please tell me. thank you.

Water deionizer

Hi I was wondering if any one had a good idea of how to build a water deionizer.I'm just starting a car valeting business and need deionized water for final rinsing of cars to prevent water spots as we are in an ultra hard water area and normal rinsing leaves water spots no matter how well we chamois it. I have a 1000L IBC tank that we use to collect recycled and rain water which i want to use to rinse off the cars. As we are in a water controlled zone we have to recycle and filter our water and also it is a ultra hard water area the filters to deionize the water for rinsing cost around £90 plus postage and only last 10-15 cars which is to really killing our business. It is costing us around £9 a car to just rinse them and on a basic wash we only charge £10 which as you can see is not viable. Thanks in advance

Solar Filter for Telescopes

Having seen some predictions of increased solar activity over the next two years, I decided to make a filter so I can check it out with my trusty telescope. To start out, I constructed the rig shown in photo A, and practiced with it by cutting disks of plain glass. Make a table like that in photo C so you can make a continuous score on the glass, without stopping. Put oil on the wheel of the grass cutter. Be sure that the surface you work on is flat. You can skip this if you want a square filter. After scoring, your glass should look like that in photo B, with a uniform and even cut. Next, put the scored glass on a soft surface like a mouse pad, with the scored surface wetted with water and face down. Press on the back of the score with a dull nail to start a crack. By continual pressing you can watch the crack propagate all the way around. Then, make 8 radial scores from the circle to the edge of the glass and propagate those cracks in the same manner as the disk. When you do it right, you get a result like photo D, where the pieces were separated for illustration. When you get good at this with regular glass, you can cut the mirror into a disk. With the mirror, you score the glass on the side that has the metal coating. Or, you can just cut the mirror in a square instead of a circle. Photo E shows an uncut and a finished cut mirror. The mirror came out of the back of a discarded projection TV. Some of the mirrors are plastic films, some are second surface, some are first surface glass but the metal coating is too thin. There are many variations, but you need to find a first surface glass mirror that reduces the light level by 12 stops (as measured by a LunaPro SBC light meter). Photographically, this is like reducing the light level from F1.4 to F64. This level of light reduction will be hard to find. WARNING: Use of a mirror with a thin reflective coating can result in eye damage if used to view the sun through a telescope. I have access to a smaller commercial filter to use as a guide. This filter produced a bright blue image of the sun, so I added a red filter at the eyepiece. This combination produced a normal yellow image of the sun. There were no significant sunspots visible, so I didn’t bother taking any pictures. The Filter is mounted to a screw-in lens cap.

How can i make my turtle tanks filter quiet??

Here is the deal, I've got what basically amounts to an indoor fish pond about 2 and a half feet away from my bed. It's got a filter made from a rubbermaid tub that sits on a shelf next to it, water is pumped up from the tank, into the filter, then out the top where it pours down a pair of PVC tubes back into the water, about 3 feet below it. My problem is that when the water splashing in the bottom of the pipes sounds just like someone is peeing, beside my head, all night, every night. it;s a bit of a nuisance. My first thought would be to shorted the distance between the filter and the water level, but i cant fill the tub to the capacity it was meant for(300 gal) without it falling through the floor, and i don't want to have to explain why i dropped 300 gallons of water and turtles on my neighbors bedroom to them or the management. My second thought was to build a stand in the tank for the filter and lower the filter, but there isn't enough room in the tank for that. So, throughts, ideas, anyone?

Water Tunnel Testing

So, my measurements professor got us permission to fill and fire up the water tunnel in the measurements lab.For those that don't know, a water tunnel (like the one below), pumps water from one end of a tank to another. The water goes through a conditioning filter (to make the flow nice and even), and then it passes through a tunnel (that blueish area in the picture). You can then add dye or solids to the water to see how a fluid flows over the object.We're allowed to bring in one item (per person) to put through the tunnel. The tunnel is a little more than a foot wide. What would you like to see in there? After the lab, I'll post up pictures (and possibly video) :)Keep in mind that the object should be heavier than water (e.g. no balloons :P). See the photo results here!

Setting up a new apartment, what would you do?

Greetings all, I am soon to move to South Korea and will be sharing a bachelor with my wife on her ESL teaching contract.  I would like to see how many instructables we can take advantage of while there and want to get input from this totally awesome community and what they have used/would suggest to use. Our Goals: - Reduce energy use - Increase healthy environment/food/liquid intake - make best use of small area - nothing permanently altering structure of apartment. Example: The first problem we have to overcome is the problem of a single bed.  While it is easy to say 'just go out and buy a double or an air mattress'.  The problem is that we have to keep the original bed and have zero storage space.  The idea that I found which could potentially help through the use of a Loft Bed instructable which would help us 'lift' the single bed out of our way and allow use to effectively use it for any guest that may stay over as well as get a bigger bed into the apartment. I also saw a really neat instructable using Tesla CD-Turbine and thought maybe there may be some useful electricity to be gained since there is no water bill. Also any number of various LED projects for lights and such. I used this instructable for water filtering at home and will do so while in Korea. Any other ideas would be welcomed!

Tap water often quite dark and with a strong chemical smell - what to do?

I don't ask for much help but this time I am reaching the end of my knowledge and patience with landlord and water authorities.That's the story so far:When I moved in I did the usual checks and tests but of course did not pay too much attention to what comes out of my taps.After a few weeks I noticed that the drain in bathroom sink seems to rust on the enamel....Easy wipe with some cleaner fixed it but since the actual drain is made of brass I started to wonder what caused the discoloration in the first place.A bit later I had my niece here and while she had a shower I realised that I only get very little hot water from any other tap in the house.Landlord stated that no one would need hot water from two outlets at one and refused to have it checked out - WTF??Paid for plumber myself and the result was not good.The hot water system is connected "open" was his answer after half an hour of messing around.For the lame man it means that whenever there is a pressure difference between hot and cold water it will go through the hot water system.Did not fully get this so he showed me in the laundry.Open the hot water a bit and it runs out fine, open the seperate cold water tap and the hot water stops.This even worked when turning on the cold water in the kitchen.The water is able to go back into the hot water system through the outlet much easier than through the inlet side.And to top it off, the current install basically turns the hot water system into a giant bypass valve :(Paid a few bucks extra so I would get that same explanation in writing for my landlord a few days later.The next and growing problem is the chemical smell.If highly chlorinated then my aquarium test kit would show this and recommend to use a water conditioner when using tap water to top the tank up.And it does not really smell like any chlorinated water I know.Definately a chemical cleaning or sanitation smell though.The plumber could not do more than basic tests so I contacted my water supplier.To my surprise they were happy to send someone out for free.Of course they only cared about their product and all tests were limited to the tap right next to the water meter.Pressure ok.Water clearity ok.Chlorine levels next to zero."Harmful substances test" came back negative as well.It was recommended that I have the plumbing under the house inspected for the water color changes and smells/bad taste.And I had to admit that what came out of the front tap really looked and smelled fine.Work slowed me down for a while and the problem only came back to my mind when I came back from a weekend trip.Needed something to drink quickly so I filled a glass from the tap.It came out like from a rusty bucket.Definately of brownish color and the chemical smell worse then ever.Had to let the water run for about 15 minutes to get something out I dared to drink.Installed a water filter a few days later and though all is good now.Pre-filter, 0.5 micron filter and then a cartridge with activate carbon.Am a single and the unit was meant to be for a busy family.Should have been good for well over 5000 liters of water.I don't really use much in the kitchen for drinking and cooking purposes so I guesstimated I need new filters every 12 to 18 months at worst.They lasted less than 4 weeks before the water came out in drops instead or running....Cutting the fliters open revealed that both pre- and fine filter were fully blocked and brown.Provided all documents and evidence to my landlord but again was told there is no issue and the house is just old :(As a last resort I tried to get under house yesterday to check the pipes itself.Couldn't get all the way in due to all the pipes from the ducted heating system.But I found a bad mess of literally all bad plumbing skills.From the water meter a just finger thick copper pipe goes under the house.This goes into some 1/2" galvanised steel pipe and it look the main way of sealing the connection was some glue or resin around the screw fitting.The same old gal but thinner pipes go close to where the connections for water go.There the "plumber" again used screw on press fittings and glue to connect to thin copper pipes.Hot water is designed the same way, one big gal pipe straight through and then thin copper pipes connected to it.I am not a plumbing expert but I do know that copper and steel won't mix if water is involved.Assuming the hot water system is affected in the same way then this giant battery is eating away the thick gal pipes while supplying me with all the byproducts of this galvanic reaction.The landlord won't budge unless I take legal action and around here you would want to do this as a tennant.Right now I have a long garden hose from the front tap going through my kitchen window :(At least I get usable drinking and cooking water this way, my fish no loger suffer losses after the topping up the water from this hose either...But this can't go on like this.Once the gal pipes start to leak the landlord is required to act but not before that.And chances are these thick pipes will last a few more years before failing :(If i wouldn't know better then I would say at some stage the ducted heating was replaced and to have more room all but the main gal pipes were removed.All copper pipes are the flexible ones and are bend to follow the floor and wooden beams.What are my real life options to fix this water problem?A set of filters ever 4 or 6 weeks sets me back close to 120 bucks each time, hence the garden hose :(What sort of tests can I make to determine what is actually created in my water that causes the smell, taste and discoloration?By the way: a simple rust test available to check for corroded steel pipes only shows traces of rust even if the water is of a slight brownish color.Replacing the piping myself is not just far over my budget but also not allowed for a tenant.And somehow I still wonder if there is more hiding in the walls but could not get close enough to see if the opper pipes actually connect to the taps or just another piece of old steel pipe.Apart from the obvious, what are the dangers of having steel and copper pipes mixed like this for my health?

Home-Brew water purification unit

Lately I've been looking into home water purification; and I was hoping I could get some community support, and ideas :) So far in my online research, I have found that active carbon works well as a filter. So, I was thinking I could sew some between two pieces of fabric, and then put it at the bottom of a pvc pipe, thus letting the water go through it; From there, I got the idea of making a wooden box, which will be just about (1 ft x 1 ft) all the way around. I'd also line the inside with a plastic sheet, like those found in a home pond. I think that would make a good housing for the filtering equipment; I'm still working out the details on the actual purification of the water; I have a basic understanding of it, though if you have some insight, please do share :) Also, if active carbon would be a good solution, where would be a good place to find it; I live in the Glendale, Arizona area, so somewhere around here, if you could.

Custom Fish tank stand

I am creating a custom fish tank stand from 2x4s and sheet wood. I plan to paint it black but I ran into 2 problems when I decided I didn't want the hood that came with the tank. 1) The lighting.     I have a pretty good history with LEDs so creating the lighting will not be too hard, only real issue I run into is sealing the lamp. I plan to use an acrylic sheet with holes drilled for the white and blue LEDs. White for day and a row of blue for moonlight on a 3 way rocker. I just dont want water to penetrate the holes from the ports for the light to damage the components. 2) The filter.    This is where I am at a loss. I plan on making something similar to this: http://tinyurl.com/fishtankdesign But I have no idea how to an external filter rather than one of the regular table top aquarium ones that would not look very pleasing on a nice stand. Any ideas questions comments or concerns please ask.

automated hydroponic system ?

Hello, I want to make automated hydroponic grown plant system that will sense condition and provide sufficient Mineral Nutrients for growing hydroponic plant.  we place the seed into water, seed grow into water , growth should start after 2 or 3 weeks.we don’t feed fertilizer until the first set of true leaves appears When seeding develop their true leaves and roots. Its time to feeding fertilize.we need to provide right fertilizer for good growth Most common fertilizer is NPK, after two or three weak or after the first set of true leaves appear we need to fertilize plant. Fertilize approx every two weeks Automated system (small and low cost system) Parameter – conductivity Project part list Electrodes probes Micorcontroller Amplifier or filter Resistor A to D converter Ic Volve or relay Automated system that Add more or less fertilizer into water ,that maintain conductivity range Best time to fertilize plant Time- fertilize plant after their active growth ,after two or three weak or after the first set of true leaves apper we need to fertilize plant ADD small value of NPK into water because small plant take less fertilizer After two weeks Add large value of NPK into water because large plant take large fertilizer Provide enough NPK to complete their life cycle we can measure conductivity of whole solution. how to make Automated system that will Add more or less fertilizer into water on basis of conductivity If plant need more or less fertilizer system  will adjust itself

Help needed with recycling greywater to flush the toilet!

We have a small shower and toilet room and what I'd like to do is use the water from the shower and store it in a tank so that it can be used for flushing the toilet. It sounds simple enough, but I'm new to building things like this so I have a few questions to ask the forum! 1. I've read that greywater can go stagnant quite quickly. Would this matter if it was only being used to flush the toilet? If it is a problem, is there a simple/compact/cheap way of filtering the water first? 2. You'd need to make sure that there was always enough water in the tank to flush the toilet, so there would need to a minimum amount in there that if there wasn't enough greywater from the shower available, that it would get topped up from the mains water. Would you use a float valve for this or is there a better way? 3. I'm not exactly sure where I would be able to position the tank. Either way I would probably have to use a pump of some sort, either to get the greywater into the tank or to get the water from the tank to the toilet. Should I just use a submersible pump or something else? Any other ideas or small projects that people have done would be great to hear about. Thanks James

Partial solution to trash in water? Maybe.

 Hey everyone, I had a couple of ideas for getting trash out of our storm drains/oceans/streams/rivers, the first one, this one has a couple of flaws: This is a very basic idea to skimming trash off the surface of water, a net. Preferably one with small holes to limit the amount of trash flowing out of it with the water. BUT, fatal flaw: It can also catch wildlife in it, and I'm still trying to figure out how to work around this. Any suggestions? Second, a filter of sorts for storm drains/streams: Imagine a metal mesh wedge, kind of like a snowplow wedge, that would go in front of drains and such (I'm thinking more for the type of streams and drains that have those big tunnels going under roads and sidewalks and emerge on the other side). The wedge could allow water to flow through, but direct trash off to the sides to collection tanks. I'll try to illustrate it below.                       - - - - - - - - <0 (the lines would be the stream, then the wedge, then the drain/tunnel opening. I couldn't do the tanks...) I'm eager for any suggestions/tips, improvements, and thoughts on these!
