The Naiad chromogen removal filtering system is nice.  It is available
through Triange Biomedical Systems, TBS

Bleach treatment is not considered the proper treatment of DAB
for the obvious reasons in a message preceding this, unknown
products formed with bleach and DAB.

Dapsons Hazmat book gives a formula with potassium permanganate/sulfuric
acid for correct treatment, but you need to find out if you can
drain dump this "treated chemical waste" from your waste treament
facilities.  They often frown on this practice.  Would hate to get caught
and pay any hefty fines levied by govt agencies.
