Press Release Summary:
Designed for use in new and existing TRU TEMP® low-temperature black oxide finishing lines, NEAR-ZERO™ Water Recycler allows user to recycle and re-use process rinse water by filtering out free and emulsified oil and detergent residues, reducing rinse water consumption up to 99%. System maintains rinse water pH at near neutral level for continual reuse. After about 1 month, filter media is changed, all 3 rinse tanks are changed and refilled with clean water, and cycle starts over.
Original Press Release:
New NEAR-ZERO(TM) Water Recycler Introduced for the TRU TEMP Black Oxide Process
Eden Prairie, Minnesota – Birchwood Technologies announces introduction of the new NEAR-ZERO™ water recycler for use in new and existing TRU TEMP® low temperature black oxide finishing lines.
Designed to reduce rinse water consumption up to 99 percent, the NEAR-ZERO system allows the user to recycle and re-use process rinse water by filtering out free and emulsified oil and detergent residues. The system maintains rinse water pH at a near neutral level for continual reuse.
The NEAR-ZERO system provides TRU TEMP black oxide process users a cost-effective way to conserve water, particularly in areas where water use is restricted or where normal water and city sewer services are not easily accessed. For example, a normal TRU TEMP black oxide process line with 100 gallon tanks utilizes three flowing rinse tanks, each requiring a flow rate of about two gallons of water per minute. When operated for one shift per day for a month, the total water consumption is about 63,000 gallons – all going to city sewer as non-hazardous discharge. Though the actual cost of this volume of water is usually modest, a flowing rinse system may not be a viable option for all users.
The Near-Zero Water Recycler allows the user to recycle and re-use the water in the rinse tanks for about a month. Then the Near-Zero filter media is changed, and all three rinse tanks are changed and re-filled with clean water, and the monthly cycle starts over. Total water consumption equals 300-500 gallons – a 99% reduction.
The NEAR-ZERO water recycling system is designed for TRU TEMP process lines of all sizes and is completely pre-engineered for fast setup. The NEAR-ZERO system has easy to operate controls and has an enclosed cabinet with a spill containment base. The system can be integrated into most TRU TEMP tank lines in only a few minutes.Â
The NEAR-ZERO Water Recycling System is an important new option for metal finishers in water-restricted areas. These include 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 instances, the Near-Zero Water Recycling System can be installed on a new process line, or added to an existing line as a retrofit. The new system can make the difference between successful in-house blackening and no blackening at all.Â
