Hi Deb.

I don't know much about screen printing but I talked to Greg Johnson at
Rainbow Signs (612)576-6572 about this situation. Greg is a former
chair of our Environmental, Health and Safety Task Force at PIM. He
would be happy to talk to whoever is interested regarding this problem.

Here in the Twin Cities, the wastewater standards are enforced at the
point where a facility's entire waste stream enters the sewer at the
street. This commingling of plant wastes effectively dilutes individual
process waste streams to the point of meeting the discharge limits for
BOD and total suspended solids (TSS).

However, Rainbow Signs does use a closed loop solvent cleaning system
for the initial cleaning of their screens so that the greatest amount of
screen waste is captured in the closed loop system. After the initial
cleaning, the screens then go to the water wash system for final
cleaning. This minimizes their BOD and TSS loading in their wastewater
without having to install the more expensive water filtration and
recirculation system.

Just another option to consider.

I have been working with a intern from the Illinois EPA who is assisting
local decal screen printer. The screen printer has been having problems
with meeting the local discharge limits for BOD and suspended solids and
interested in installing a waste water filtration and water
system. Does anyone have suggested vendors for this type of equipment?
