RE: (All) Waste Prevention Technology

[Kenneth Saulter <KJS@iti.org>]

Check out wetting agent/fume suppressants  as an alternative to control
devices to meet the hex chrome emissions MACT standard.   At about
1/10th the cost the fume
suppressants prevent the formation of chrome plating mist by reducing
the surface tension of plating bath thus preventing the formation of
bubbles that break through the bath surface.  Helps with drag-out also.
No energy cost per se.  If a foam version is
used there is a safety issue in terms of spark ignition of hydrogen.
Current products
generally offer low foaming fume suppressants.  Pitting has been a
traditional issue for older versions of these products.  Newer products
are widely used now for decorative chrome.  We are testing their
efficacy  for hard chrome under an EPA program.  Early
tests were positive.  We hope to tackle the quality issue head-on.
Regards, Ken
