would need changing more often than a sand/charcoal filter.

Having worked worked on pools, the sand filters are amazing. I've worked on very very green and dirty pools and the filters help get them spotlesly clean.
I think they filter up to around 20 to 40 microns and uses silica sand.
A facility to backwash the sand and clean it is useful.

what about charcoal based filters?

Charcoal for later apparently.
Anyway I plumbed in the basic cheap as chips £1 each filters 50,20,5 micron And attached a whale domestic pump. Not a big pump and through the 1/4 pipe I timed it And it takes around 30 seconds to fill a litre pyrex jug.
My incredible math brain tells me this is 2 litres per minute.
Thats OK but how long for?
I ran some of the water into the kettle and made a cup of tea.
Very smooth much nicer than tap water.
I have now added the 4 litre per minute UV lamp.
I'm wondering how long the filters will last.
Just going to have a rest now as am feeling a little queer if I don't make it it's been nice knowing you !

Well that's about 50 minutes and still running. 2 litres per minute so should be about 100 litres. Been running it into one of the main tanks.
50 micron filter does look dirty and its slowed down a little bit but this is without any settling time and no sand filter or anything before the 50 micron so I fancy it as an option for washing water.
Might even have a shower to celebrate it. First this month!
I reckon the idea is to fill the settling tank in morning then pump next morning allowing 24hr for settling then refill if afrer pumping.
With the outlet half way up the tank (I stuck the hose in place with magnets) its about 45 litres for each run.

Fair point.
Maybe not the shower then.
Good advice always welcome !

Anyway
I am still alive but not quite as alive as the water now in the bulk tanks.
They were nearly full anyway but I reckon I got around 200 litres before the 50 micron filter got blocked up. And that was without using the settling tank for its designed purpose ie not waiting.
Put another £1 filter in just the 50 micron one and flow was back up to 2 litres per minute as before.
Seems OK.
I slept for an unusually long time last night after the river water tea and now I have got a very small extra ear growing off the end of the right ear.
I'll have to see what its like in a week or so.
Have since added chlorine liberation tablets to the water tanks.

Note to self: bring bottled water.

Anyway
I also bought a £45 3 stage Reverse osmosis system to see what happens. That is now plumbed into the domestic circuit pumping the filtered water from the main tanks. It looks like with a normal 45psi Shurflo pump it's going to only do about 1 litre per hour.
Which is actually ok to be fair. Just leave it on all the time. Use that for drinking water and it's more than enough.
So I might just leave it like that. There is a dedicated drinking water tank which I usually top up with 5 litre water carriers. Separate pump and tap so if I dump the RO water into there on a continuous basis I can see it working quite well actually.
I'm quite happy to be washing in aquatabs and UV treated 5 micron filtered river water. That's not really a problem but for drinking I think it would be nice for it to be a bit cleaner.
Usually people use a 60+psi pump for these but I think looking at it for light usage I might just get away with my 45.
Would be quite nice as it's rather a tidy setup like that. I put a solenoid valve in the 1/4 plastic tubing so could easily set up a timer for it.

It's a bodge at the moment. Does work quite nicely but not very refined. Initial filter manifold from the settling tank. The left hand filter (50 micron) does block up very fast obviously. I think a 100 micron sock on the pickup in the tank would be sensible probably. Mind you if it does 200 litres of water for £1 of filter it's not the end of the world. With a pump onto 1/4 hose. Goes through the UV lamp Then onwards to main tanks. Hot and cold is plumbed to these tanks. I added aquatabs. Small RO system under sink which is plumbed to main water supply 45psi Shurflo pump. Seems to make about a litre and hour so far. Pump cycles in every ten minutes or so. Could do with higher pressure pump certainly. It's useable though. The RO system I chose has a 5 micron filter then a carbon thing then the RO membrane. No idea how long it will work for but it's an interesting experiment. The RO output water tastes flat no sign of chlorine so the carbon filter obviously sorts that out.

That looks brilliant, and it solves the problem that stopped me taking this any further, which was that I would use loads of power to run the pumps and filter enough water, if I put all the water I needed through the reverse osmosis filters.
By only running kitchen tap water through the RO system, you've cut down a lot on the power usage.
One thing that does spring to mind, perhaps not a major issue on the rivers, is heavy metal filtration. I think one of the RO filters might be doing that, but not sure.
On a canal, I'm not sure I'd want to even wash in water filtered down to 5 microns. On the systems done by the hgy on youtube, I think he uses 1 micron as his smallest filter- but then those are intended for canal water, which is more 'challenging'.

I understand RO itself blocks heavy metal contamination ( I believe the molecules are too big to get through the membrane)
