Birchwood Casey’s Near-Zero water recycling system enables users to operate the company’s low-temperature Tru Temp black oxide system using almost no rinse water, providing water savings over conventional flowing rinse systems.
A standard BC100 Tru Temp process line uses three flowing rinse tanks, each using about 2 gpm of water. When operated for one shift per day for a month, the total water consumption is about 63,000 gal. The water recycling system enables users to recycle and re-use the water in the rinse tanks for a month. Then the filter media is changed, all three rinse tanks are changed and re-filled with clean water, and the monthly cycle starts over. Total water consumption with the recycling system is about 300 gal.
The system is suited for installations where normal water and city sewer services are not easily accessed, such as in small shops on septic systems, sewer districts that restrict total water volume or in plants where the blackening line is located in a warehouse without water/sewer hookups. In all these cases, the system can be installed on a new process line or added to an existing line as a retrofit.
The system is designed for Tru Temp process lines up to 150 gal in tank size, and is pre-engineered for fast setup.
