The new Lumiclad electroless black oxide process for aluminum is now available in a new zero-discharge configuration that totally eliminates the need for a drain connection, according to manufacturer Birchwood Casey. The system uses ion exchange technology to purify and recycle the rinse waters, resulting in a “closed-loop” zero-discharge installation. The technology is available for all size systems, including 40-gal, 100-gal and larger capacity custom tank systems.
The Lumiclad process is an alternative to black anodizing for aluminum components. This 30-minute process produces a durable, satin black finish that is 1.5 microns thick, with a smooth, clean surface that is electrically conductive and tightly adherent to the aluminum substrate.
