If anyone wants to lend a hand with text, I'll bash on with a couple more diagrams for the wash tank page. Efforts to date here: http://www.biopowered.co.uk/wiki/Water_washing
For those who currently water wash, how critical is drying the bio with heat or will just settling suffice?
-
I've always done the same thing ever since day one when it comes to drying fuel. Apart from the brief foray into WBD my water washing has always resulted in the same method. When my fuel shows signs of clarity and the water is clear coming out it's then time to turn on the heat. I heat the fuel to 60-70C with my air pump on max to aid disipation of the available heat. I then let it bubble until it becomes ambient. When the heater gets switched on you can hear the popping and crackling of the water/moisture being heated.

I think you need heat or at least airstones,i would,nt trust just settling
-
Just seen Nigels post,i do pretty much the same
-
Thanks Both.
So Ideally I need to show a heater in all the wash tank variants then? GL didn't show one on his wash tank, but I can see the need for one.
Fancy doing the bubble wash text , Nige, and Keith the mist wash?
-
We,ve turned them into washing and drying tanks with the addition of airstones and heater
Still not sure about your airline comment in the other thread? could you explain a bit more

I use pneumatic exhaust silencers to bubble my bio, so can get photos of those ... can anyone offer photos of bubbler tube rings, fish tank air stones or I think some people use grinding wheels?

Yes, on your diagram you show yellow air lines running down the inside of the tank with air stones on the ends. These seem to terminate below the water level, implying they might be for bubble washing rather than drying the bio. But from later posts they do seem to be used for the latter.

AH,with you now
Yes one goes to the bottom,one a bit higher but they dont get turned on untill the water has being drained so they are in the bio then

Have you got, or can you get, a bigger non-ebay photo please, there might be copyright issues!
And what do you recon to showing a heater in each wash tank?
-
I think the heater is a good idea,i will take a photo in the next few days-got the dreaded lurghi at the mo,feel like s++t ,not going anywhere :'(
-
Thanks Keith, no rush.
Hope you feel better soon.
There's a lot of it about, wife and several fiends have it and at the New Years party I went to, about 20% were no shows due to flue like ailments.
I'll modify the schematics to show heaters.

Nearly finished a page of text re water washing and heat drying. I just need to take some photos of my system. I'll send it all across when it's finished.

Nige,
That's great, I was about to try and make a start, never having water washed any bio!
I've tried to split the page into three sections with a diagram for each (although I know two or more can be combined). Is your text specific to bubble washing or does it cover all methods?
I did a little research and found some people in the US wash with a mixer paddle in the tank. Do you think that's worth including, even if only to steer people away from the design as it seems prone to creating emulsions?

My text will concentrate purely on bubble washing. I'll leave mist washing to those who use that particular method.
I've not seen any info regarding paddle mixers so can't really comment. As for creating emulsions i think that all water type washing increases the likelyhood of an emulsions...we just need to emphasize the care that's needed.

That's great, I've got some text from Keith on mist washing along with the GL text.
-
Theres really very little involved in mist washing,just a case of turning the tap on enough for a decent spray pattern and making sure the outpipe is where you want it,when the water runs clear - job done,normally about 6 hours
Any specific questions just ask
-
Thanks Keith,
I'll have a bash over the next couple of days and perhaps you can critique the section when I've finished.
-
Keith,
Mist washing text is up at http://www.biopowered.co.uk/wiki/Water_washing I leant quite heavily on Girl Mark's page from the CBT, so have a gander and let me know what you think.
I added a bit to GLs section regarding an idea I had some time ago about using a ballcock (couldn't get away with saying that on the other forum!) as a safety shut off for the wash water. Haven't tried it but I can't see why it wouldn't work. I think I have an old brass one in the scrap bin. If I have, I'll modify it and take a picture or two.

Quick glance-looks good,i will have a proper look tonight
-
Looks great Julian, those diagrams are, as ever, top notch!
-
Thanks, they all need heaters adding and I'll show at least one with a bio pump and filters as per Keith's original.
-
yup kewl and just luv ya diagrams.
