i asked a question earlier about science projects and this one got me interested, but this is alll the information they gave me and i am confused.

Make a water filter out of a cup, some solid carbon (if you can get it) , rocks, sand and coffee filters. Did that when i was in 9th grade a long time ago, got 1st.

canu plz help? i need help on how to do it...like a procedure kind of..i already looked it up and they were diffrent projects..idk

You don't need the sand or the solid carbon. You can just get some coffee filters and the type of carbon sold in big box pets shops like Petsmart or Petco that comes in a big plastic bottle for refilling aquarium filters - or even open up a new aquarium filter and use that carbon.

Put the coffee filter (cone type would work best in a funnel, or a disposable cup with holes in the bottom to allow for drainage, or something else that can hold it, but still allow it to drain. Put the funnel or cup over something for the filtered water to run into. Add carbon to the coffee filter. Fill with tap water and let it drain through. As it drains it filters the water somewhat.

That's the concept behind the filtered water pitchers like Brita & Pur. That's also how aquarium water is filtered in some tanks, besides the option of using a bio wheel. That's how air is filtered in some air filters as well. The carbon absorbs smells and impurities (but not all), and then gets replaced after a period of time when it's used up.

This is a large residential location with about 10 people. I am searching for a filtration system for the whole house. tap water comes out at 320ppm, and they would like one filter to use fr everything, pool, showers, dishwasher, lawn... Are there any systems that drop the ppm through a filter without having a waste line? All i am hearing about is carbon filtration or water softening. They dont want water sofeteners.

There is a whole spectrum of water treatment systems around for treating water for a variety of contaminates. Solids, if your are not talking about dissolved solids, are a simple filter, but this is rarely any real problem. If you are talking dissolved solids, TSD, you probably need something more sophisticated. I would send a sample of the water to a lab that does the testing, Google "water testing lab" and see what their results or if it part of a municipal water system get their test results and their recommendations for treatment. Could be activated carbon, simple filter, reverse osmosis, distillation (although not for the volume you are talking) and possibly others or combinations of them. Google "home water treatment" to see what is available. Consumer Reports puts out a good stream of info on this, try your local library to gain access without subscribing.

Price: $10.60 $10.60

Standard 2-7/8-inch OD x 9-3/4-inch Length
Meets all plumbing codes
Low pressure drop makes it ideal for whole house or areas where higher flow carbon block filtration is needed

The laboratory procedure is as follows:

Mix 2 grams of salicylic acid with 4 milliliters of acetic anhydride in a 125 milliliter Erlenmeyer flask.
Add 3 or 4 drops of concentrated sulfuric acid to the flask and stir.
This is an exothermic reaction and so heat will be liberated when the reaction starts. If the flask does not warm, add another drop of acid to the flask until the heating effect begins.
Once the heating effect is detected, heat the reaction mixture in a water bath at 50 degrees centigrade for 5 minutes in order to drive the reaction to completion.
Cool the flask and then ADD 40 MILLILITRES OF WATER. Stir the aqueous mixture until a solid is formed and becomes well dispersed in the liquid.
Filter the liquid by suction using a Hirsch funnel and wash with cold water.
Use hot water to crystallize the filtrate.
If necessary use carbon to decolorize.
WHAT IS THE WATER USED FOR?

The previous answer is partially correct.

Water reacts with the excess acetic anhydride which is converted to acetic acid.

Since the product is only slightly soluble in water, this also makes it possible to collect the product as a solid.

I need a system that will removed dissolved solids and also partially soften my water. basically, I would like to remove Ca, Mg, Na, K, nitrates, phosphates, chlorine, etc.

I dont care about organic, and the water source is municipal, so there is no sediment.

Im not going to be drinking the water, I just need water that has low TDS.


I guess it really boils down to this:

Do I ABSOLUTELY need an RO system, or can I get by with some kind of In-Line GE water filter system that does not utilize some kind of polyamide resin (membrane).

Another option is a Mr. Clean Auto dry system, which uses a 2 stage filter. One stage is carbon, but Im not sure about the other stage.

I am not really understanding what you want. You have already answered your own question. What you need is a reverse osmosis system.

Hello again! Recently I have been having some trouble with white cloudy water in my aquarium. In my first aquarium (10 gal) I had some plastic plants and a couple rocks. I didn’t cycle it properly with all of the water changes and tests so the water became incredibly yellow and cloudy. I decided to start over in a new 15 gal aquarium. It was my fathers when he was a kid and is a solid 33 years old. It was in perfect condition after being neglected in my grandparents basement for the last 20 years! No cracks or anything! Well anyways, the water is getting cloudy in this aquarium too! It has been open for 2.5 months. Currently it is being properly or rather, more properly cycled. Unfortunately, I had to add all eight fish I had in the ten gallon the day after I opened the 15 gal. So now, all of the levels are a tad high. my levels are:
Nitrate- 10.0-20.0ppm
Nitrite- 0.0ppm
PH- 6.4 (went low after a water change, currently working on it)
Ammonia- 0-0.25
I think the fast transfer of all of the fish contributes to the cloudiness. I have 8 fish in the tank. I am under all circumstances overstocked. I have: 2 serpeas, 2 redeyes, 2 mollies, 1 pleco, and 1 kissing gourami. Ok so now on to equiptment. For filtration I am running an aquaclear 150 with two sponge inserts and 1 carbon. I run it 24/7! For oxygen I am running an air pump with and airstone. This is a planted tank with co2. I am running a DIY co2 system until I get my hands on one of those high end pressurized systems. I do have a check valve in the tubing! I ran the co2 directly to the input on my filter. The plants are: an aqua fern, another fern, a grassy plant, an anubia, and another stem plant that I cant remember the name of, all from petsmart. I also have some rocks in the tank which until recently relized are spray painted. They came with the tank originally. Also another note: All of this stuff worked perfectly for the tank when it was originally run in my house! Although we didn’t have any live plants. I decided to use a fluorite substrate both for looks and functionality. It has the worst dust problem though! (any ideas on that?) As for lighting. I have the original, yes, original fluorescent bulb that came with the hood in like the 70’s! Just to make it even better it doesn’t have a wattage label on it! It is fairly bright and the plants aren’t dead so I think I’m good. As for chemicals I use jungle brand start right, stress zyme, and nutrafin plantGRO iron enriched. Well I need two answers;
1)Why is it cloudy?! Overstocked? Just cycling? Give it time?
2)How can I get the cloudiness out?! Water changes? More chemicals? To much chemicals?
Please help and sorry for the novel of info above! If you need any more info please let me know!
Thankyou!
the filter is rated for 10-30 gallons so i think its sufficient. Im by no means a fish expert though...

your aquarium is flourishing bacteria. you should minimize the water changes, just once a week. its good you know all this stuff, most people dont even care, they take the easy way out. though i recommend seachem stability. It is a very good product and helps double the speed of the ccling process. patience is the key to an aquarist. it might take over a month, but hey look on the bright side, your future fish will be happy and live long =]
