UVF® Technology for Solid Liquid Separation


The all new, patented design of the UVF® rotary vacuum disc filter utilizes proprietary filter media designed to optimize solid liquid separation by incorporating hydrophilic-hydrophobic multi-capillary flow paths.

Our vacuum disc filter media, combined with proprietary design innovations, ensures the highest and most efficient throughput of any vacuum disc filter – outperforming both cloth and ceramic. In many cases UVF® provides significant advantages over other separation technologies such as filter presses.

Most Effective Technology for Mineral Concentrates and Tailings Dewatering


Focusing on mineral concentrate and tailings dewatering, the proprietary design of the UVF® filter media provides very high throughput rates, low filter cake moistures and enables backwashing at up to 10Bar (145 PSI) where required. This ensures excellent solid liquid filtration rates and long filter disc sector life.

UVF® vacuum filter disc field testing of mineral concentrates, such as iron ore concentrate, have demonstrated throughput rates exceeding 3 to 10 times that of other separation technologies. For example, many competitive technologies advertise 1-1.5 mtph/m2 whereas the UVF® filter has achieved in excess of 4 to 10 mtph/m2.

Thicker Dryer Filter Cake


FM Technologies’ UVF® vacuum filter disc media combined with our proprietary cake removal system, allows for direct scraping of the filter media – enabling filter cake up to 3 inches (8cm) thick to be effectively discharged.

Rotational speeds of the filter disc sectors are adjustable from less than one rpm to greater than ten rpm – providing the operator with a wide range of parameters to ensure the most efficient production of thicker, dryer filter cake.

Lower Capital Expense and Lifetime Operating Cost


Comparative CAPEX studies performed by a Global Engineering Consulting firm experienced with iron ore filtration plants have shown that a 50% or greater reduction in equipment and installation costs is achieved using UVF® Technology versus other solid liquid separation technology.

Significant OPEX savings are realized using UVF® Technology which delivers the highest production rate per unit filter area, produces thicker, dryer filter cakes, provides longer vacuum disc filter sector life, eliminates additional air requirements via the removal of a snap-blow cake discharge, and utilizes a vacuum system with significantly lower power consumption.

Welcome to FM Technologies

FM Technologies was founded by Steve Benesi in 2013. Steve’s key objective was to innovate and develop new filtration technologies that outperform all current technology by a magnitude or more. This resulted in the development of Universal Vacuum Filter® technology. Prior to founding FM Technologies, Steve Benesi developed a highly successful pressure filtration technology that was later acquired by a large mining equipment supplier. Steve has spent over 35 years in the filtration industry.

FM Technologies is a SEPARATION AND FILTRATION TECHNOLOGY CORPORATION that DEVOTES >95% OF ITS RESOURCES to developing the world’s highest performance filtration and separation technology. FM TECHNOLOGIES core emphasis is on the development of innovative filtration technology – this is in contrast to many large companies where the emphasis is on sales of existing technology and lack focus on product innovation.

FM Technologies is based in the USA with testing and manufacturing in both North and South America.
