Selective IX Systems

Ion Exchange systems are deceptively simple - all the hard work occurs at the molecular level in the resin. Water to be treated is run through the resin and emerges with barely measurable amounts of contaminant. Economics dictates what happens after this.
Copper, Nickel & Lead

Copper, Nickel and Lead

For these metals, the cost of the Ion Exchange resin is signifigant in comparison to the metal being recovered. The metal captured by the resin can be removed using regenerant and the resin reused again and again. Typically, you can get 2 to 4 years of use out of resin before it must be replaced.
Quite often, our Ion Exchange systems are coupled with a Rota-Cat. The Ion Exchange system removes metal from the water, regeneration removes metal from the resin and the Rota-Cat is used to recover metal from the regenerant.

Gold, Rhodium and Palladium

For these metals, the cost of the Ion Exchange resin is very small in comparison to the value of metal being recovered. To guarantee maximum recovery, no attempt is made to reuse the resin; instead, it is smelted to recover as much metal as possible. This is called sacrificial resin.
Trionetics has developed a unique method of unloading and reloading the resin. Water is circulated through the column to wash the resin out. Fresh resin is drawn in by vacuum. The entire process is completely automated and takes minimum time and labor.
