Using a 1 micron filter bag as a Millbank bag

[haydenw]

Hi guys,

I was wondering, would a 1 micron filter bag (such as this one here) 18" 1 MICRON FILTER BAGS,BIO DIESEL,VEG OIL , W.V.O Work as a replacement Millbank bag when out and about. (And either using chlorine tabs or rolling boil to get rid of any other water nasties).

Just looking for a cheap alternative to water purification where time is no issue.

Cheers,

Hayden.

Your link didn't work for me but I reckon the filter will do fine. A Millbank only removes sediment and particles anyway so there's still a need to boil the water. I used a buff on my last trip as I couldn't bothered messing about with my filter which was packed away, anything to get the lumpy bits out is good enough.

Hi Rich, cheers for the reply. Hopefully this link will work... http://www.ebay.co.uk/itm/18-1-MICRON-FILTER-BAGS-BIO-DIESEL-VEG-OIL-W-V-O-/180837728037?pt=LH_DefaultDomain_3&hash=item2a1ac4bf25

Cheers, Hayden.

Hayden, I should think the flow rate on these would be slow at 1micron without a good waterhead to push it through. As Shewie says the millbank is solely to remove debri so that when chemical treatment is applied there are no 'bits' that could protect cysts etc.
A millbank bag is also very durable being cleaned by turning inside out and flushing. Wouldn't 1micron take some cleaning to prevent reduction over time of the flow rate?
If you know this already please excuse my comments. Alan

Bought my Millbank new from EBAY, you don't see them often and they tend to sell for betwean 20 to 25 pounds

one of those would work fine, i micron might take some time though, you can use an old t/shirt to filter water, as above it only gets rid of the bits...

you could even sew an old t/shirt into a tube shape with one end closed, and that would const next to nout, maybe double layer it just to make sure...

you could also bung it in the washing machine when you get home to clean it up...

jobs a fish.

Looks like a goodun, though that water does get filtered rather quickly.

Would something like a coffee filter paper be OK to strain the bits out the water and then either boil or chemical disinfect?

I have a mill bank bag and also a Katadyn combi-filter which gets the water along with some chlorine as near to tap water as possible but am trying to reduce my pack weight a bit for a potential Lake District visit.

I would not have the fuel to boil all my water so most of it will have to be chemically treated after filtering.

I picked up a 1 micron filter bag a few weeks back for about £2. It was my intention to use is a pre filter. It has a really slow filter rate which I found could the imporved by first thoughly soaking the bag but this still hgave a rather slow flow rate. In the end I cut a circle out of the bag folded it to form a cone then filled a 1 liter plastic bottle with water and user a length of rope to tie the cone filter to the neck of the bottle and then queezed the bottle forcing the water through in a matter of seconds. while I doubt the filter will will be very long lived it is a cheap easy to use and light weight.

Not really.

As has been said Millbank bags are a "pre filter" to remove the larger debris. A 1μm bag will soon clog and will need a pre-filter anyway.

1μm isn't fine enough to stop all the biological nasties ie virus, some bacteria. Also these filters take an age to dry and go mouldy very quickly

save some money get these then boil the water if its only to replace a Millbank bag
If you re going to filter water with a potential high degree of contamination you will need a proper commercially manufactured filter;so if you don't have one its about finding a relatively safe source filtering the large debris out then killing bacteria.
