Let us explore how a Vortisand® high efficiency media filtration system will optimize your water treatment efforts. Traditional sand filters are limited in their technology; the lack of fine filtration with low capacities created the demand for an improved system. The Vortisand® filter has been chosen by many customers around the world for its high efficiency and submicron performance, higher flow, compact design/footprint, automated operation and lower cost of operation.
High Efficiency - Submicron Performance
The high efficiency of the Vortisand filter lies in its unique use of microsand media coupled with cross-flow filtration, allowing the capture of particles under 1 micron in size.
The cross-flow technology enables optimization of the media bed, ultimately improving filtration capacity, and allowing the design of a horizontal vessel. With a single 36-inch vessel, the horizontal design is capable of treating a flow of up to 1,090 gpm, offering unparalleled performance and value. The filtration velocity through the media bed is up to 5 times faster than traditional filters, at 25 gpm/ft2 (60 m/h), while delivering higher water quality.
Lower Cost of Operation
An important consideration for any filtration system is the overall operating cost. The Vortisand filtration system potentially reduces 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 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 total suspended solids (TSS).
- Low Maintenance Costs: Requires little human intervention, with minimal maintenance tasks.
Evoqua’s Vortisand systems provide an automated experience, along with maintenance reminders and a user-friendly interface to ensure operating and maintaining the system is an easy task.
The effective use of microsand media ultimately results in requiring less media, enabling the system to achieve high levels of efficiency with a smaller footprint (up to 80% smaller and lighter in weight than traditional media filters). The system is also unique in its design, allowing for customizations to better suit the application at hand (such as a vertically stacked system capable of doubling the filtration capacity within the same footprint). The unique lightweight and compact Vortisand® filter design also provides both shipping and on-site infrastructure savings.
