3M Zeta Plus EC

3M™ Zeta Plus EC Filters

Zeta Plus™ EC purifiers are high capacity purifiers designed to remove metallic ion contaminants such as Ca, Fe and Na from photoresists, solvents, ink jet and wastewater applications in a single pass.
The purifiers offer unique advantages in contaminant reduction because of enhanced electro-kinetic properties.
Since most suspended particles have a negative charge, the strong positive electro-kinetic charge of Zeta Plus EC enables the adsorption of contaminants that are too small for removal by mechanical straining.
The Scanning Electron Micrograph (SEM) in picture 1 illustrates the enhanced particle removal mechanism.

Features / Benefits

• Reduction trace metals to low digit ppb level
• superior metal reduction capacity, lower cost-of-ownership
