View Full Version : any one know how to filter bath water???
hey hey all
I was wondering on a way how to filter dirty city water for a nice clean bath?
dose any one know?
so far I was thinking of some kind of a pillow case filled up with activated carbon or something similar
do you think it could work? hopefully with out murking the water
I dont mind tiny amounts of grainy carbon
mabey some type of a plastic tube with a filter on the end to keep in the charcoal
anyway grate to here what people think/say/iders :D

I read about this just before reading your post, it's a shower filter.

I use a shower filter, but it doesn't filter Flouride. Mine is like this one: Amazon.com: Rainshow'r Dechlorinating Shower Filter CQ-1000 NH: Health & Personal Care@@AMEPARAM@@http://ecx.images-amazon.com/images/I/21aVC6ZpYzL.@@AMEPARAM@@21aVC6ZpYzL

.
That inspired me to check out the Amazon UK site as I live in Europe and shipping from the states makes many things to expensive to buy. So I found and ordered this shower filter, not too expensive, though don't know how much a replacement filter costs...
Universal Shower Filter. No more scale - new ceramic technology removes 99% of chlorine from both hot and cold water - proven to help eczema sufferers - kills bacteria. Only 36mm in diameter - fits any shower. Also fits on dishwashers, washing machines, etc. Free standard delivery.: Amazon.co.uk: Kitchen & Home: Spring Shower Filter@@AMEPARAM@@http://ecx.images-amazon.com/images/I/21yXg1HmfDL.@@AMEPARAM@@21yXg1HmfDL
The company Aquatier makes filters for the whole house so having a bath of filtered water is possible...if you can afford it.

You've clearly never used one.
It would take a day to fill a bath with RO water and it would be cold when you got in. Mine is a standard unit and it only produces about 20 gallons of RO water a day, even though it is specified as producing 50 gpd.
yeh good devices I seen them on ebay before but the problem they wont fit on my bath and the shower has no force at all to be able to use one
I seen a ball type device you hang under the running bath tap but they dont seem to filter it
I want to get all the trace toxins out like arsenic lead and other chemicals
would adding a pillow sack filled with activated carbon would it soak up all the crap???? and im sure it would be reusable many times possibly?

The trouble is knowing whether or not all of the metals have been removed.
If you have a hot water system supplied by a header tank in the loft, you could go down the RO route, but would need to cap off the existing cold feed pipe and as I said before it could take a day to fill the tank. If you've got mains hot water such as fed by a combi boiler or pressurised hot water tank, then you would need some sort of in line filter. A carbon drinking water filter I was looking at on line is good for up to 8500 litres before you need to replace the element. About 85 baths.
You would need to check the flow rate to see if enough passes to run a combi boiler, if not you could put 2 or 3 in parallel. You could also put one of these in line in your cold feed pipe if you have a header tank, the slow flow rate wouldn't be so important in filling a tank. would just take longer.

Clearly you dont know me to comment on what I have an have not used.
It sounds like the filter you have is a small one commenly used to filter drinking water. If you used your noggin, you would search the web and find that there are filters out there which can filter hundreds, some thousands of gallons per day.
Why would it take all day to fill a bath? Cleaver people would filter the water before its heated (storage tanks) rather than after the heating stage, hence it would still only take the same amount of time to fill a bath this way as it would when not using a filter.

I never meant for anyone to filter after the heating stage. Where did I say that ?
I'll try again then, Ro systems waste about 4 times as much water as they filter, so if you were using one in line you'd need a water service that can deliver something like 4 to 5 times the normal flow rate.
Of course you can use one in a stored hot water system, but in your previous post you just recommended an RO filter, you didn't mention any type of domestic hot water system. If you were on a water meter the sheer amount of water going to waste would probably be cost prohibitive.
And no, I don't know you, so I have no right to presume what you have or haven't used, but I can't believe anyone who knows RO filters would consider them in a domestic hot water system, so that's where I got my assumtion from. Sorry about that.

The cheap filters work with mains preasure to force the water through the membraine, where as if you had a pumped system, the water which you call waste (with the contaminates in) can be pumped back through the membraine thus eliminating the amount of waste water

salt from the Dead Sea is supposed to kill everything harmful and totally purify your water
thanks everyone for the reply
I would love a RO filter but the problem is that I am in a rented flat and the water has no mains pressure from the boiler
as for directly in to the tank, its an good ider but I need something cheap and make shift and that doesn't need a plummer,,,
hopefully something that can be made by all on a cheap
I will look in to the dead sea salt too
I am thinking this stuff in a pillow case it must be better then them £50 bath filters that only removes
CARBON AKTIV ( ACTIVATED CHARCOAL )

http://fastfishfood.com/Activated-Carbon-Granules-420g-Bag
The favoured way to keep the aquarium in tip top condition. Use freely inside all types of filter internal, external using a net bag.
Activated carbon for removal of odours, discolouring tannins, chlorine, chloramine, heavy metals and chemical pollutants.
Uses adsorbsion method so will require regular (Monthly) changes, or leeching back into the tank water will occur.
Always refer to instructions when using other water treatments such as medicine, as the effectiveness of this product may cause medicines to be ineffective. Simply discontinue use during treatment.
Granular Form (also available in pellets).
i went with this
iQuatics 1kg Premium Activated Carbon - Marine/Tropical

I was thinking to add it in to some type of plastic tube and place directly under the running bathtap
hopefully I can make the holes small enough so the water slowly filter Thur it
surely it will be better then nothing,,, hopefully should help
p.s after sitting in the bath I am going to need more then 1kg I think
mabey 6kg crushed up would be better
as for testing the results,,,, would any one know how to do that????
should I just let 0.5 litre of filters and unfiltered just evaporate to see residue or is their any other ways to run a test on the results??...
the filter is going to be a tube, in it will be a pillow sack and I will add a few small holes evenly around the tube until I get the tight flow
Activated carbon - Wikipedia, the free encyclopedia
Granular activated carbon (GAC)
Granular activated carbon has a relatively larger particle size compared to powdered activated carbon and consequently, presents a smaller external surface. Diffusion of the adsorbate is thus an important factor. These carbons are therefore preferred for all adsorption of gases and vapours as their rate of diffusion are faster. Granulated carbons are used for water treatment, deodourisation and separation of components of flow system. GAC can be either in the granular form or extruded. GAC is designated by sizes such as 8x20, 20x40, or 8x30 for liquid phase applications and 4x6, 4x8 or 4x10 for vapour phase applications. A 20x40 carbon is made of particles that will pass through a U.S. Standard Mesh Size No. 20 sieve (0.84 mm) (generally specified as 85% passing) but be retained on a U.S. Standard Mesh Size No. 40 sieve (0.42 mm) (generally specified as 95% retained). AWWA (1992) B604 uses the 50-mesh sieve (0.297 mm) as the minimum GAC size. The most popular aqueous phase carbons are the 12x40 and 8x30 sizes because they have a good balance of size, surface area, and headloss characteristics.

hmmm dam don't seem to stick to some base metals well
oh well it will filter some stuff out and reduce some base metals
apparently chalk/calcium will remove fluoride so I can bang some of that in their if it don't seep
bump????
no help anyone???
guess i am on my own on this one

Active charcoal wont take away the trace metals in water. I have a couple of marine tanks and I have to to RO filter the water before I can use it in the tanks due to the trace metals in there. Copper is a killer for some inverts etc.
I use active charcoal in filters for tkaing waste out, it removes odours etc but it wont do what your looking for.
