The EPSE™ Method provides a unique and patented solution for the treatment of materials containing soluble metals. Method produces a metal-free overflow and practically insoluble multi-metal precipitate, which can be recycled further. The EPSE™ Method suits particularly well for industrial and mining acidic wastewater and process water containing soluble metals and it has been successfully tested for 50 metals, presented below.
EPSE offers their clients a comprehensive technical solution and its’ treatment process creates excellent results. EPSE™ Method can be used for both continuous (24h) or batch run according to the customer’s wishes and it can be integrated into existing equipment.
Operating principle
The EPSE™ Method water treatment process is based on the dosing of the EPSE™ chemical and the adjustment of the pH level. The process forms a metal free overflow and an insoluble precipitate that can be classified as inert waste, which does not require special storage or special permits like hazardous waste does. The Method’s operating expenses and its’ implementation does not typically require big investments. Because the EPSE™ Method isn’t dependent on temperatures, energy is conserved remarkably.
The EPSE™ Method is non-selective and is proven to be effective to all of the processed metals even in small concentrations. The precipitate formed in the process settles rapidly and it can be used as raw material in many ways.
