We've been using it for around 8 months with minor issues here or There, and today we went through 5 of the 75 micron filters. 5!!! And it's still not working properly.
Wondering if anyone else has been having issues like This, or know of what we might be doing wrong.

That is pretty much the same thing I have heard 2-3 other people all say. Your not alone.

sucks, we are trying to figure out what to do, as it's severely killing our reclaim process right now.

We have been using for a few months now and just recently started to have to change the filters more frequently. Which emulsion are you using? We have noticed some emulsion will require us to change filters almost daily. We have been having best luck with chromablue or the Ryonet hifi blue but still changing filters almost weekly now. You have the 25 micron filter as the last one before it exists to the drain pipe?

So Blue Moon added a pre-stage water settling tank system that allows them to go through filters 1 time a month. We are looking at building something like this but it looks pretty easy to do yourself too. https://www.youtube.com/watch?v=SJ-p2M_1MJo (https://www.youtube.com/watch?v=SJ-p2M_1MJo)

I have the same problem with the Blackline system.

This is disappointing to read as we have been looking to switch from our Blackline unit for this same reason.

We use Saati PHU2, which is pretty close to the CryoCoat. It's a high solids emulsion. I think a pre water settling tank like Ryan mentioned might help actually.

I wondered how those filters would do as well, I ended up having a custom tank made that holds about 40gallons of water with 3 settling sections , it seems to do the job with just a stained water going down the drain , we have to clean the sludge out about 3 times a year and usually get about 25 gallons.

We had tried saati emulsion once and had major issues so went back to the blue which hasn't been as bad but we still see frequent changes.
I saw his setup with the extra container but space is tight for us don't think we can rig all that up around the washout booth.

Had similar problems with ulano orange and other high solid emulsions. Screen guys works 40 hrs a week cleaning screens and would have to change filter once a week. Couple things we changed and no problems since only change filters about once a month. Changed both filters to 75 microns, made the emulsion remover concentrate stronger to help break it down. Installed new ryonet screen recirculation cleaner, had old parts washer left ink and residue on screens assume was part of the clogging of filters. Best thing we did was build settling tanks. Very simple just two tote bins some sink parts and sump pump. Now we have crystal clear water coming out

Not to derail, but the video is the 1st I've heard that Marvin Guillot had passed away. I guess that's what happens when you stay shelled up at work. He was the guy that trained us on our 1st auto the diamondback. A real knowledgeable guy. Sad.

We have a DIY setup, loosely inspired by the Blackline system. Between the sink drain & the sump tank (aka tote bin), we use a smaller bin to hold disposable filter media, which catches the biggest chunks & goo, and can be easily be pulled out & replaced. (We use cheap screening fabric from Home Depot/Lowes, cut into pieces to fit into the pre-filter bin.)
Weprocess a very low volume of screens compared to most of you guys, so I'm not sure how well it work for others. But I expect the idea could be adapted. Anything that would keep the bigger, semi-solid pieces from ever reaching your real filters should obviously help. We don't have a settling tank, so perhaps that's all that's needed. But if not, perhaps the combo would.

We used a similar set up, but we built it ourselves. you will never get, "clear clean crystal water" out of any of these. But, Like Ryan mentioned, you add a big tank, mount your sump off the bottom so that you aren't sucking up the setiment, "solids", you will filter better. We have to drain outside, so we ended up going with the CCI clearwater system. You actually end up with crystal clear water. All solids, all colors are taken out of the water before it's pumped outside or to your sewage line. It's really impressive. The only draw back is that you are left with the clay that encapsulates all of the colors and contaminants. The draw back is coming up with a way to let it dry and harden. For us, we have a couple racks outside with a few old newmans, we dump the clay on the screens, it sits in the sun for a few days turns to rock and then it's safe to dump in the dumpster. This system is EPA certified, not cheap, but if anyone is looking for a true "crystal clear" filtering method, it's the way to go. It was originally designed for the promo printers using the really nasty stuff on pens, bottles ect to the California EPA standards which from what I understand are the most strict. It just so happens to work on any nasty crap that is in your water. Anyone who's come here and seen how affective it is, is blown away. I think the Ryo filter system would be a great way to "pre filter" the stuff before our system, which would allow us to use less of the flocking powder, and have less clay to deal with ect. But really, everyone's area's are different in what is actually allowed.

Maybe Ryonet can provide higher mesh screens to pre-filter the water before it hits the "real" filters. If the final screen was 305 or even 355 mesh it may help to keep the round filters working longer.

This would not work well.
We have one of these filters and the screens plug up to fast now.
We are pulling the unit out way to often to clean the screens because they clog to fast and overflow.
This filter is more work than you think.

We have been using the Ryonet system for around a year.
Its great. Sure it requires maintenance, but pulling out the screens and cleaning takes
all of 5 minutes.... We put a cut in half panty hose over the pipe, throw screens in booth
and clean. The Yam Bag catches the slough. It drains, and then in the trash... We always put a
cheapo furnace filter on top as the 'first stage' of filtration. Goes right in the trash after a few days,
but keeps the tape and larger stuff from clogging filters.
We go through quite a few screens per day, but we have never experienced having to replace cylinder filters
at the rate that Eric is talking about. Thats strange.. - John

Has anyone tried Easiway EDF-100 Filtration Unit? It looks like it uses a 100 micron sock filter but no other real info on how the rest of the unit is configured.
-
I like that idea, John. We're looking at the ryonet unit for our next filter system and my plan was to add a sheet of filter media over the top as the first layer of filtering to keep everything else somewhat more clean. Easy and cheap to replace.
