Thanks Scott, here are the questions:



Did you custom build the 3 part separator?
No, I have the steel eagle separator. If I was to do it again, I would use three tanks so that I could have a larger capacity, and more time for the solids to settle out

What mods did you do to the water boy internally?
I have not done any mods to the internals of the water boy. It is silly simple, about the only thing that you can do is put in a better oil capture system, and maybe some finer filtration media.

How efficient is the settlement tank on the steel eagle compared to the drop out tanks?
I don't know.

How do you like the built in cyclone separator on the steel eagle?
Honestly, I think that it serves zero purpose.

what would you change on the vac end of the process?
I would come up with a larger filter for the blower, because I have had it get plugged on multiple occasions. I would also make it lower profile. As it stands, if I am going into a garage with a height of 6'6" I have to remove the cap on the blower to make sure I clear. Since there is so much wasted space under the blower, I would think it would be easy to do. I also would put a larger fuel tank on the blower. I hate having to carry gas cans. They say they plan it to be able to work an 8 hour day. That is wildly optimistic at best. I can get, maybe three hours out of a tank of fuel on it.

So you prefer the pump similar to what Robert and Larry uses on the Recycle 16 for pumping out of the H20 Boy? I prefer those pumps myself.
I don't know what kind of pump they use. I should have looked closer when I was in Ft. Worth. I do like the symer geyser pumps, though. Their only drawback is that they do not have a float switch on them.

The final stage polishing filters, you like the bigger ones that Tom Durbin uses. Me too, but how big would you want to go? Mine are the 8" diameter, 24 housings. I think that since I am using them in a multi stage process that is sufficient.

What sequence of micron polishing do you recommend?
I prefer a 200 micron filter, a 100 micron filter, a 50 then a 20. I have had zero pump problems with that size of filter and it slows down the filters getting plugged with debris. I have actually run with no filters on a long term, when I was in a bind, without any problems. So a 20 is plenty sufficient for my needs.

In your experience would you choose bag over cartridge?
Cartridge every time. My experience is that first the bags plug up quickly, because they have no surface area, and that, if you have a plastic inner housing for the bag, it melts, thus ruining the seal, and the inner housing.


Thanks Scott, appreciate your time

Hope this helps, and that you are able to read it.
 
I've got a garage set to start the end of next week and a 1000000 sq ft one tenatively set for may. Hopefully I will have a riding surface cleaner built by then. Scott if you have a solids drop out before your vac tanks do you think the ows could be eliminated. I'm trying to free up space on my reclaim rig and not include the ows and just go with 3 150 sq ft cartridge filters.

Good question, it depends on how big the drop out tank is, I was attempting to find the rate of settlement for sediment in a undisturbed stream.

Anyone want to guess how long clay takes to fall out of suspension and what micron size it is?
 
Nigel I think 'clays' are at the smallest end of the scale and could possible stay suspended?

Nope, won't happen. There is too much turbidity in the water, because of the vacuum, the water coming in, and the water going out. It does separate out the larger pieces of dirt, etc. so that it does not clog the filters, and the OWS. Consider it a prefilter, rather than a complete filtration system.

They are the smallest that could settle out, and if it does not, it would get trapped by the filters we use in our indusrty today. If you can drop it out that would make filtration less hectic

Scott had some questions a few post up.
 
dang, I wasn't paying attention. There really is no standard that I have seen. Some garages I have cleaned are so steep that entering them my hitch has drug. Most I have seen are about a 15% grade. It makes a challenge without vacuum recovery, because the water runs down to the bottom so fast, and it can easily run right out of the garage.
Nigel, if you have questions please feel free to call me.
 
Wow, great video.
 
I saw the video after Jim's of Russ talking about cleaning a gas station. It may just be me but I I got tired of turning my head 90 degreees to the left to watch it :scratchhead:
 
Just came across this thread on a google search.


Man I sure have done a great deal of investigating over the years. (Flocc, Cyclone, Media, cartridges, Tanks, pumpouts performance, Vacuum Blowers, Reynolds # , OWS's, design, build and testing),


Here is what I know,... the latest pw filter updates for 2011:


Sirocco improves sand trap (nice)

Hydrotek redesigns their portable unit (nice)

T George Podell uses multimedia housings now (quicker maintenance), with SS drums (nice)

Deluxe Cleaning Supply designing a 50gpm filter for about $20K due March 2012 (this should be something to behold)

Jim Gamble of Crystal Cleaning Company LLC is building a new smaller filter unit, due end of 2011. (Knowing Jim you probably can expect nothing like it on the planet, and maybe yellow)

Nigel, there is another cyclone separator out there, built by a good looking company.

I saw it on the new Cleaner times magazine, there was an ad by MiTM (I think) where it was a pump out drum with filters and the cyclone separator. The Cyclone was not pictured but it was on the ad so I looked up on the MiTM website and the picture is there.

The flow is high and it looks to be made out of metal.

I found some other similar cyclone separators but they are huge and industrial for larger flows that a parking garage will never see, even with 10 or more rigs running.

The cyclone separator that MiTM is using looks like it might be as good as the Multi 50, maybe better but I think it only separates down to 200 micron if I remember correctly.
 
Thanks Chris, had not seen that one.

The Mitm portable filter system looks good.

It is similar to the Ramteq unit a few years ago.

I have looked at the Lakos separator a few years ago and a couple other cyclones here in the USA and Japan, the Lakos and the Multi Cyclone are two that does not require pressure to operate like some of the others I have seen (although the other pressurized inlet cyclones can go to 5 microns, some even claim 1 micron, but they are in the $3k to $5K range).


The Multi Cyclone was a better theoretical fit for my filtration design/budget.

This thread has great filter info all in one place
