Liquid Filtration

USAR provides recovery and refining services for spent weak acid filtration and product filter applications.

• Like the hot gas process for recovery and refining, USAR employs a Wet Recovery Method in preparation for the refining of precious metals captured by the filter media. 
• All processes for filtration recovery are refined using a hydro method that ensures the best outcome for elemental metal returns.
