Title: Do you filter your washout room?
Post by: ericheartsu on February 15, 2012, 08:07:34 PM

Especially your washout sink? if so how and with what?

We wash out a pretty good amount of screens daily, and do both textile and flatstock inks (waterbased, plastisol, UV), and we often wonder if it's wrecking havoc on our sewage system, especially since it's been raining a ton here lately.

ECIN Washout booth has a filtration system built in. It's basically a couple of fine mesh screens and some filtration media. Does the job. The booth rusted out though. Going to get a Blackline setup next probably.

we use a settling tank see pics below.
The process is simple the solids settle out to the bottom, dirty but solids free water skims off the top and gravity does all the work there are no moving parts. We are a small shop and find that we get about 6-8 inches of muck at the bottom of the bucket that we muck out once or twice a year as required and send to the solids to landfill.
the process would work the same for much larger shop you would simply require a larger receiver tank. the key is retention time in the tank and gravity skimming off the high water line.
Hope the pics help.

Cool.  That's a nicer version of what I have for my settling tank.  Which is a mop bucket with no lid.  Washout just dumps in and then bucket fills up and drains!  A way to improve it would be to put a filter media above the bucket but not sure it would catch any more than the natural settling effect.  If you watch the bucket fill up and drain you don't see any solid particles entering the drain.

Mooseman scores again!

I swear I don't have a man crush on you or anything. LOL

I just built my drainage bin and now I'm going to have to rethink my entire setup!
