Dyna Clean

Hello again!

Does anyone have info on Dyna Clean?  It is used by drycleaners 
to "re-recycle" sludge and perc.  The sludge is mixed 
with gallons of water, which brings the perc levels down to an allowable 
level that can be discharged through the sewer system.   This 
machine is not part of the dry cleaning process, so the waste is 
still generated.  I don't think it's legal practice to "dilute" the sludge 
and dispose it through the sewer system.  But there could be an 
argument that it's a treatment onsite.  I would really appreciate 
any information on this process.
