L.A.W,you could just fill a bucket with water & let it settle for a couple of hours & then tip it through some sort of cotton garment into another bucket & then you should have the water you require.

In the Army we were issued a bag called a Milbank filter which was heavy cotton used to remove the larger floaties out of ground water before adding puritabs.

We're mucking around with alum and turbid creek water. 3g/100L seems close. Any one with advice?

The problem with alum in the OP's situation is that they want to treat large amounts (well relative to other campers) and it will require a seperate tank/container for floculation to occur. You will need to decante the water into the final tank or if the raw water is of a poor quality, it may need another form of filtration.

You really don't want to place alum directly in your storage tank as it will create a sludge on the bottom of the tank which will require cleaning out. Any movement will resuppend the sludge into the water.

Good stuff, though will not necessarily get rid of all colour eg. tannins.

Microfiltration pumps would be a better option.

These guys have made a filter that will do what you want. Developed for use in disaster relief. Not sure if it's available to the public.

Go to the link and look for the SkyHydrant.

I bought a filter cartridge housing on e-bay (new) for $25 and bought locally a 5 micron filter works great and gravity feeds thru filter easily. A note of caution though there are two grades of filter cartridge NOMINAL which is a bit iffy on the actual rating or ABSOLUTE which means if marked 5 micron it will filter to 99.9% 5 micron. My son also uses 5 micron (absolute) to filter his home brew to take out most of the sediment and it still leaves enough yeast in solution for second fermentation and leaves the brew crystal clear and no sediment in the bottle. Most filter cartridges can be back washed to extend their life. As an example he bought a 1 micron NOMINAL cartridge and it is not as good as his 5 micron ABSOLUTE

Skyhydrant looks interesting and sure it does a great job however to big for mobile use.

Will try a 5 micron filter and see how it goes. Water pump shop told me 25 micron was smallest you can get.

Thanks all for replies.

or was it a case of "25 micron is all we sell"?

Just remember that at 25 microns, it will not filter protozoa such as cryptosporidium, giardia etc The smaller the membrane, the better it will be to filter bacteria, viruses and protozoa. 5 micron or less would be highly desirable.

I remember when I worked on a station NW of Gundi in Qld during the drought we were drinking/showering etc with straight dam water. We would pump the water straight into the house rain water tank then spread (throw) either gypsum or calcium (can't remember exactly but it was white powder) and it would settle out all the sediment - leaving water most clear. Best part was having to climb inside the tank when it had emptied (in iddle of summer) and clean out the foot of silt on the bottom of the tank.

Tasted like it smelt - bloody ordinary.......now I know why I like XXXX so much.

Filters go down to about .1 micron but are expensive for absolute
I paid $18 for my 5 micron absolute Have seen them at Bunnings
If you go carbon 5 micron it will take out all the nasties as well and quite safe to drink
Do a google and you will be surprised whats there. When buying a cartridge I was given a lot of misinformation from sales people. Make sure if you buy a cartridge it is ABSOLUTE rated. A lot of people think because they were sold a cartridge for their home use and rated at 5 or 10 or 20 etc thats what they are getting, nominal rating doesn't mean a thing
PS Tell us the outcome once you have bought and tried
