Vortisand Cross-Flow Submicron Filtration

Microsand Media Filtration Systems

The Vortisand® systems are synonymous with water filtration, serving the industrial water markets since 1986. The award-winning Vortisand filter is a High Efficiency Microsand Filtration System. It is a high capacity media filter that combines cross-flow dynamics with microsand media to achieve submicron filtration performance. This technology allows the unit to operate at filtration rates of up to 5 times greater than those of traditional media filters, while filtering 10-50 times finer.

With over 2,500 installations worldwide, the Vortisand filter has become a leader in high efficiency filtration systems.


 Advantages of Vortisand Filtration Systems

​Smaller Footprint
Up to 80% smaller & lighter than traditional filters.
High Efficiency
Submicron filtration performance! 10-50x smaller than particles retained by traditional MM filter and centrifugal separators.
FasterThe filtration speed is up to 5 times faster than multi-media (MM) & traditional filters at 25 gpm/ft2.
​Save Energy
Reduce/Eliminate fouling, scaling & biofouling! Significant energy savings is achieved in heat transfer applications.
Lower Maintenance
Reduce labor, maintenance & operational costs! Requires little to no human intervention
​StackableThe design of the H2F® makes stacking vessels possible, doubling your capabilities within the same footprint.
​Save Water
Up to 50% less water required during the backwash cycle compared to traditional media filters.
Be Green
LEED credit can be achieved with Vortisand by using less water and energy for your building.


 Why Choose Vortisand?

High Efficiency  – Submicron Filtration

The system's high efficiency lies in the unique use of microsand and cross-flow filtration. Vortisand® systems can capture particles under 1 micron in size, 10 to 50 times smaller than particles retained by other media filters.


Higher Flow

The cross-flow technology has allowed us to optimize the media bed depth and improve filtration capacity. By doing so, we were able to design a horizontal vessel that provides the ultimate in filter technology.

With a single 36-inch vessel the horizontal design is capable of treating a flow of up to 1,200 gpm, offering unparalleled performance and value. The speed is up to 5 times faster than traditional filters at 25 gpm/ft2 (60 m/h), while delivering higher water quality than traditional media filters.

With an array of design, instrumentation and control options, our team of engineers will develop a solution that will meet today's goals and tomorrow's challenges.

Lower Cost Of Operation

An important consideration for any filtration system is the overall operating cost. The Vortisand filtration systems help reduce operating costs in several ways:

  • Reduced Water Consumption: Requires up to 50% less water during backwash when compared to traditional multi-media (MM) filtration systems.

  • Energy Savings: Significant energy savings is achieved in heat transfer applications by helping prevent the formation of sediment and bio-film, leading to greater heat-exchanger efficiency.

  • Reduced Chemical Costs: Significantly improve the effectiveness of chemical treatment by reducing the total suspended solids (TSS).

  • Low Maintenance Costs: Requires little to no human intervention, with minimal maintenance tasks.

Automated Operation

Vortisand systems provide a fully automated experience, along with maintenance reminders and a user friendly interface to make operating and maintaining the system an easy task.

small footprint

The effective use of the media bed ultimately results in requiring less media, allowing our customers to achieve high levels of efficiency with a smaller footprint (up to 80% smaller and lighter than traditional filters). The system can be customized to offer a vertically stacked design capable of doubling the filtration capacity within the same footprint.

This unique lightweight and compact design provides both shipping and on-site infrastructure savings.
