Birchwood Technologies offers the Near-Zero™ water recycler for use with its TRU TEMP® black oxide system. The recycler reuses the rinse water in the process line, reducing typical water consumption by 99 percent, the company states.
It can be installed on a new or existing black oxide system. It recycles and reuses the rinse water in the process tanks for about a month. Then the operator changes the filter media, purges the rinse tanks, and refills them with fresh water.
The recycling system is designed for black oxide process lines with tank sizes up to 200 gal.
