Birchwood Technologies has introduced the new Near-Zero water recycler for use in new and existing Tru Temp low temperature black oxide finishing lines.
The Near-Zero system is designed to reduce rinse water consumption up to 99 percent, allowing the user to recycle and re-use process rinse water by filtering out free and emulsified oil and detergent residue. 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," said a company spokesperson.
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.
According to the company, 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, 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 pre-engineered for fast set-up. The Near-Zero system has easy to operate controls and has an enclosed cabinet with a spill containment base.
"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," said the spokesperson.
