Ion Exchange with Zero Discharge
Keeps Rinse Waters Out Of Drain
Designed to remove dissolved ions and solid particulate material from process rinse waters, the Birchwood Technologies Ion Exchange System allows the user to operate an antiquing system and a variety of metal finishing processes while keeping drains at zero discharge.
The primary benefit is that the process rinse tanks can be physically disconnected from the drain.
System operation is simple and is the best option for meeting stringent sewer regulations. The Ion Exchange System removes contaminants from the rinse water and generates de-ionized water to be re-used over and over. When the first set of resin tanks is saturated, the second set is connected for uninterrupted system operation. The saturated tanks are sent out to a regeneration facility licensed to treat the waste.
The regenerated tanks are returned to the system user ready for re-use.
Existing finishing lines also can be retrofitted with Ion Exchange.
Let our experts guide you. We build complete turnkey systems to meet your needs. We'll train your operators at your facility for correct system operation. We provide continuing service after startup.
Adaptable to all finishing lines, the Ion Exchange system shown above has these features:
- 3/4 HP centrifugal pump rated for 6-8 gpm flow. The pump can be hard-wired for 110 or 220 volt power and is fitted with a high pressure safety stop.
- 20" pre-filter chamber with filter cartridges to remove particulates from the water.
- Optional carbon filter to remove all organic materials such as detergents, wetting agents, etc.
- Set of cation and anion resin columns, each 1.5 ft3 capacity to remove all dissolved ions from the water.
- Spare set of resin tanks, for use when initial set is being regenerated. Provides continuous system operation.
- Conductivity light indicates when resin is saturated and ready for regeneration.
- Hoses, connections and optional welded steel platform for holding all components safely in a compact, portable 4 ft x 2.5 ft area.
