The patented filtration system technology utilizes the oil- attracting properties of the fluid concentrate to carry the contaminant oils away from the process into the AFS unit. Once inside the AFS unit, the contaminant oils are stripped away from the fluid, coalesced, and conveniently accumulated for easy removal and recycling. The filter media is designed to remove suspended particles down to 1 micron without breaking down beneficial oil-in-water emulsions.
