how can i make a soap solution be filtered into clean water?

Question

i'm having a hard time w/ our project in chemistry...plz..i need ur help..i need some ideas...
we are required to make a device out of indigenous materials..a device that can filter out a (detergent/bath)soap solution into clean water that can be used again...4 washing dishes,hands...
what are some of the uncommon but practical processes can i use?
-i've heard about reverse osmosis...but how can a freshman student lyk me do such stuffs...they say its hard..
here are also some of the things that i've researched:
-electrocoagulation - too complicated ..i think it uses electricity
-coagulation
-the use of calcium carbonate ..
i hope you cud help me guys..plzzz..

tnx in advance...

Answer 1

The most simple method is to use an activated carbon (also called activated charcoal, ref 1) filter, such as those that are used in aquarium filtration devices or to recycle water at a car wash (ref 2). Activated carbon has an extremely high surface area relative to its volume - if you had activated carbon that weighed the same as a dime (2.25 grams), it would have about the same surface area as 1/5 of a football field, or about 3 tennis courts. Because detergent is a surfactant, it will coat the surfaces of the activated carbon as water passes through.

Distillation would be very difficult, as the boiling point of most detergents is about the same as water (98 and 100C, respectively, ref 3).

Answer 2

Bubble air through the water. Remove the soap bubbles from the surface. when the soap bubbles stop forming then the soap is gone. You will have to filter the leftover food particles from the dish water and you can use sand as a filter. Make sure you remove the soap first as the soap will coat the sand quickly and make it useless. The same goes for activated carbon filters. The carbon will remove the soap but it isn't practical as very little soap will blind off the absorption sites very quickly. Also you have to backwash the carbon to get the soap off...creating more soapy water. If you use a sand filter you could always throw the sand away when you are done instead of back washing it. I say this because it sounds like you are working on a project where you are in a remote location like a remote island....sand would be abundant and activated carbon kind of scarce. If you had an acid source you could create activated carbon but that's not likely.
Hope this helps

Answer 3

If you are requested to use indigenous materials, why do not try to use coagulation with calcium carbonates and after that a sand filter combined with activated carbon.

Distillation could be a good option, but you first have to build the distillator (the problem with it is the expense in fuel or gas or firewood at worst).

Good luck!

Answer 4

have been those 2d hand/ used gold fish or new? there's a conditioner for water which you positioned into the water for fish. take a seem in the shop on the fish nutrition, water conditioners. There additionally are filters for the tanks and warmers. you do not want lots of apparatus for goldfish.. They propose you sparkling the tank. you're appropriate approximately no cleansing soap. put in the issues you put in, rocks, and so on., & the conditioner for the water. in case you have chlorine on your water you are able to desire to shield it. enable the water take a seat for an afternoon or so. Did you have a thermometer. Goldfish are resilient, yet extremes at the instant are not sturdy. then you definitely positioned the fish into the water on a similar time as they're in the bag to procure them in, enable them to take a seat down back in the tank on a similar time as in the bag for a on a similar time as, then enable them to flow. they are announcing shells at the instant are not sturdy through fact they dissolve. Feed in accordance to guidelines. you are able to overfeed them. they might have been ill while to procure them.i bought angel fish and intently, meticulously set up the tank with all of the equipment, waiting era, and so on. there became right into a precise on the tank, not something ought to get in. One became caught in somewhat figurine in the tank. How? i don't understand. Killed it. Very very extraordinary the way it have been given in there. Odds against it.The others died. I had the thermometer, and so on. accompanied guidelines. They mentioned they have been ill fish. My little costly darkish frog purely disappeared. costly undertaking, all misplaced with the angel fish. they're so very noticeably. All that they had in the shop have been the sickly finding white frogs. Very very extraordinary. With all the different weirdness that went on, God in basic terms is known with what went on. I actual have not had the coronary heart to attempt back. i could have fish right here, yet in all probability does not be waiting to try this the two. I certainly omit my pets. i became into very dissatisfied. continuously enjoyed angel fish. call the shop. they have ailments or illnesses. Did you spot them biting one yet another, or their fins or tails turning black or darkish? What approximately flora? Did you positioned flora in? have been they wholesome?

Answer 5

Why not just distill the solution?

Answer 6

I would say distillation too.
