Subject: Re: [DCHAS-L] Removing Water-Based Paint Solids from Rinse Water
Note the following statement at the end of first paragraph:
The process described is intended for nonindustrial users of acrylic paints.
In Michigan (New York may have different specific rules):
We would NOT be allowed to do this treatment, without an appropriate license (there could possibly be an exception if the water was being recycled for another industrial process, but not for dumping it down the drain).
We would have to determine IF the wastes are "non-hazardous" i.e. don't exceed the metal concentrations in the EPA toxicity list. This can be done by knowledge (i.e. know what you put in, and understanding the reactions that took place) or by testing.
If the concentrations exceed toxic levels, they need to be managed as hazardous waste (HW).
If below the levels, they could potentially be managed as liquid industrial byproducts (LIB).
In both cases the wastes would need to be collected and managed appropriately.
Our waste hauler handles both types; HW and LIB can affect our monthly waste generation numbers differently.

Our household recycling center's spin if it can not be used by the recycling center pour the (water-based) paint or adhesive onto a piece of cardboard and allow the water to evaporate thus "curing" (solidifying) the paint or adhesive and once dry the paint/cardboard can be disposed of as normal household (non-haz) solid.

Re; question on treatment of paint waste
As I understand the EPA rules, we can't treat regulated waste without a license to do so. But there is a demo showing how to defloculate acrylic artists paint waste with aluminum sulfate and lime, filter, throw the water down the drain without testing, and dispose of the rest as solid waste. Art schools and businesses are doing this. The demo is at:

So va den? Any wisdom on this?
