What do i need to dry wash my bio-diesel? and what does it entail...i dont really want to water wash.
Thanks

 

This is how Magnesol works:

YouTube - Video 2:The agitation process and Magnesol introduction

YouTube - Video 3:The wash process

YouTube - Video 4:The importance of final polishing

Very simple really. Just add in the proper amount of Magnesol, Mix mechanicaly! Prefilter, and final filter ( I filter down to 1 micron ).

NO washwater to dispose of, NO washwater to dry out, Clean Fuel!

 

I plan on letting it settle for 24hrs after processing --> drain the glycerin--> then add magnesol and mix for 30 minutes --finally filter it out @ 1 micron into storage tank.

Sound good, Don?

 

That will work just fine. I used to settle for only 12 hours, but the new plant will use a centrifuge for glycerol separation. I have been doing some experimentation with this:

YouTube - High Speed, Glycerol Separation using High Voltage

Looks promising for small scale use.

 

Wow, that Electrostatic glycerol separation is slick!

As for the drywash, the filtration systems in the links posted look like some big $$$$

What are "shade tree brewers" using for final filtration after the drywash? Is anyone using a washable prefilter then a better spin on type filter for the 1 micron? Looks like the Magnesol makes a mess on in the prefilter.

 

The filter set up in the video is close to what I used, but isn't necessary. Even a simple bag filter over a bucket will work. It's best to prefilter with a 5-10 micron bag filter, then through a 1 micron absolute bag filter.

 

here is a "shade tree" or back woods style filter setup I built do to this, I also end up running it through a 1 micron absolute filter as it goes into the storage barrel. This picture shows just the bag, the bag in a fixture I built out of PVC pipe fittings with the cam lock and the setup on the hose. maybe better ways I don't know but I do get good results with this setup and the magnasol wash.



I actually run mine through a 50 micron then 25 and onto 5 and to a 1 micron and the final is a 1 micron absolute.

 

Very interesting, thanks for the pic.

I like it!

 

Google purolite. Then you don't need to worry about your filters failing to catch particles like the Mag. The purolite has other equipment needs but I think it looks promising. I have not used it but I would like to.

Also I recover all the methanol my fuel then let it settle for a few days and the left over soap settle out. Filter thru 1 micron bag filters and use it.

MonsterBaby could you give some specs on those bag housings you built? been looking for some thing like that.

 

In over 4 years I've never had a problem with Magnesol, But I've talked to several people that tried Purolite, and switched to Magnesol ( including a couple on this forum).

Magnesol does a great job of cleaning up biodiesel, is relatively cheap, and is much easier than water-washing.

 

you want info on the bags themselves? I by them from McMaster-Carr

The filter housing I built are done with 5" pcv pipe, I used the adaptors to glue onto the end of the pipe to adapt to 5" pipe threads then use the caps like you would use for caping a sewer drain cleanout (you can buy them at menards, lowes, home depot etc) I drilled out the end just slightly smaller then 1" npt and used a metal 1" pipe as a tap then just screwed in the cam lock into it. Idid have one that ended up being a little loose so I took a pvc female coupling and screwed on inside it for tighter fit.

 

What were the complaints about the purolite that made them switched back to Magnesol? Just curious as I am looking at polishing my fuel a little more.

I have the filters. The PVC info was what I was looking for. Thanks!

 

Are you using the;
Heavy Duty Polyester Felt Bags with Carbon Steel Retaining Ring?

What diameter bag fits in that handy little PVC piece you constructed?
5-1/2?

I like how simple your filter set up is.

 

Yes thats the bags I am using, trade size 4 is the ones that fit in that housing securily. my 5 micron bag is part number 5162k18 if you find that one I use all my sizes off that same line except my final filter which is part number 9844k41 for a 1 micron absolute filter. I did build a enclosed holder for the final one that also necks down to a I believe it's a 2" short piece of PVC pipe that fits snuggly into one of the large bungs on a 55 gallon drum making it easy to filter directly into my storage drum.

I like simple too. Thanks

 

Thanks for the info

BTW; I get a chuckle from your sig! Its so true.

SO, how are you mixing the drywash? Are you using a paddle or a pump?
