Looks good, but it's hard to see from the photos as they are rather small. Any chance of uploading some higher res ones to your blog?

I uploaded some bigger photos, let me know what you would like to see more clearly and I will post a photo.

Having seen a few of these systems on line and one in the flesh I still have my doubts. While it seems that filtering the oil to an acceptable standard can be done in various ways with a compact system none of them guarantee that the suspended water can be removed. I tried filtering a small batch of oil that looked good to start with, and looked really clean after I had run it through my two 5 micron house filters 3 times from one bucket to the other. However when I hot pan tested it, it fizzed like a small volcano.

Looks like clean oil, feels like clean oil, smells like clean oil, but it aint necessarily so. As for water bloc filters if they block after filtering 20 litres and they cost $15 to replace

Much better photos, thanks. A close up of the pump/filter assembly out of the bucket would be good too. I'd be interested in more details of the pump itself, i.e. where and how much?

David that looks similar to the filters I use, which I get from here.

As for dewatering, I think the only way to get rid of suspended water is heating/evaporation, which would be difficult to achieve when you're on the road. I don't think the expensive yank one in the video could do it, and I'm sure the likes of Geco (who is traveling around Oz at the moment) don't bother to dewater (other than the free water).

At least one person I know doesn't even dewater at home, and has been running for several years without any problems. Of course you have to be fairly confident of where you get your WVO from if you're going to risk it.

Personally I dewater at home because I can and it's easy, but if I was on a trip around Oz then I would probably risk it. A setup like 300D80's looks perfect.

The size of your system would appear to take up no more room that the system I linked to and obviously would be a cheaper set up but I'm wondering about how you plan actually using it on the road and what is capabilities are in comparison.

How does the system De-water or it dosen't do that part of the process?
If not, perhaps you could look at replacing the hose filter with the racor aquablock type?

The stream from the garden nozzle looks a bit thin. Have you measured the flow rate or how long does it take to fill your car?

Have you used this on the road yet and how do you plan to introduce the oil in the first place? Are you thinking of getting the oil in tins and pouring it through or do you have the facility to pump from 200L drums as well?
As the system will only handle 20L at a time, I take it you are going to do it in batch mode. if this is the case, will it be just a matter of pouring the oil in one lot at a time straight after each other or are you Planing on a settling stage at all?
If you are going to get oil from a drum, I take it you will do all the processing at the collection site?

Sorry for all the questions, just trying to get the logistics and practical application clear in my mind of how you are going to approach that side of things.

I built the system for a road trip i am about to under take this summer. The system does not de-water.

As to the flow rate i have not measured it yet but I'd estimate 20litres in around 6minutes.

I have tested it with tins from one of my suppliers where I pour it into the white bucket first. I can alternatively take the inlet hose out of the white bucket and pump directly from a 44 gallon drums.

I have posted some photos of the pump outside of the bucket. I bought the pump from a an ebay seller. Its 12v 7amps and claims to pump at 12.5l/min which it might do if it wasn't pumping through filters and the garden hose gun nozzle.

all,

I bought a genuine Flojet pressure pump and set it up as a home filtering system, but is basically the same as your mobile setup.
ie Flojet pushing through house filters.

The results were fine; for a while. The pump would not work effectively with Perth winter temperatures oils using 12mm hoses, esp on suction. It only had to lift 100mm.

The pump now sits under my bonnet and is effective in pumping diesel into the IP as a start up process so is still a useful item.

I wish you luck with this setup long term, it is neat and easy. Make sure you have a coarse filter on the inlet to avoid clogging up the pump necessitating a time consuming pull apart.

I'm thinking of putting together something similar to 300D80's for a forthcoming road trip I'm planning. However I will probably just use my hand drum pump instead of an electric one, for a few reasons:

Hardly anything to go wrong - KISS (this pump has served me well over 2.5 years)
Can easily be unblocked by turning backwards, or dismantled if necessary
Can be used to pump from large drums. This is something I found when I was in Melbourne recently, as most of the restaurants I approached used 205s or large vats instead of the 20L tins that I could have carried.

I will also try using 2 cartridge filters in series, the first one with a coarse strainer (such as this one) and the second with a 5u filter. If I can fit them into a sealable white bucket it should be neat and mess-free too.

The other thing I like about this setup is with forced pressure filtering it should be a lot quicker than gravity filtering through bag filters, which would be very difficult on the road.

I'll put the bits together in the next couple of weeks and give it a trial run.

Yes I'm planning on putting out an appeal for WVO nearer the time with my route and dates, but I'm only going through one or two major population centres (mainly Adelaide) so will need to collect my own most of the time. And I'll probably have to buy dinodiesel at some point (if I can remember how to!

).

Your km estimate is pretty close to the mark David. I'll be carrying 8 x 25L containers with me (maybe more depending on space) which should give me a range of about 2000km, but I'll fill up anywhere I can get it.

Anyway back to the pump/filter. I have a bilge pump I could use, and someone else has suggested a drill pump (as used by Geco apparently). Both have advantages and disadvantages, but I don't usually find it too hard work pumping 100L manually so I'll try with that first and see how it goes.

I think the dual cartridge filter setup will work fine no matter what pump I use so I'll get that done first.

Well I've tested my portable filtration kit, which is simply 2 cartridge filters in series as described above. Once it starts getting blocked up it's simply too hard to pump manually, so I'll have to use an electric one. I'm not sure if a bilge pump is up to the job as it is centrifugal and may not be able to create the pressure required to push it through 2 filters.

I've tried it with my gear pump (this one here) and it works great. However it's an AC motor and I measured it with my power meter at 450W under load. So to make it portable I have 2 options - buy an inverter to use with the AC motor (say 600W or more) or find a DC motor with enough torque to do the job.

I would prefer to find a DC motor as it's a more compact, neater solution, but not sure where I could get a powerful enough one that's not megabucks. Maybe a scrap one from an invalid cart or something? Any suggestions?
