Re: Water reduction for bronze art foundries

David,

They might consider evaporation of the 50 gpd to reach zero discharge or
perhaps electrolytic recovery of the copper from their wastewater if the
copper can be concentrated.

A small ion exchange unit would probably work well on the discharge if it is
a dilute waste stream

They release to sewer on the average of 50 gallons a day of water.  Has
anyone worked with art foundries and heard of any ways they could go to zero
discharge on water.  This would allow them to avoid this whole permit issue,
which would probably put a number of the smaller art foundries out of business.
