Solvay selects Neptune Benson’s Vortisand filtration technology

The H2F Vortisand is a crossflow microsand submicron filtration system. It is a high capacity, high flow automatic backwashable media filter that combines crossflow dynamics with microsand media to achieve submicron filtration at speeds up to 5 times faster than traditional multimedia filters.

Solvay’s filtration challenge was to polish treated river water out of an existing clarifier/thickener. The goal was to reduce the total suspended solids in order for the water to be used for manufacturing processes.

Neptune Benson proposed four H2F-600 filters to meet the filtration needs of the plant under varying operating conditions. The flexibility and modular design of the H2F Vortisand eliminated the need for a clear well for backwash purposes, resulting in less capital investment and reducing water consumption.

Due to tight space requirements, the design and engineering team decided on an inline configuration within a 40 foot custom designed container. The units will be fully pre-assembled, minimizing the installation cost and eliminating the need for an expensive new building.

“By using our patent pending horizontal sweeping design, the H2F Vortisand technology is becoming increasingly popular in the market. Now that the microsand crossflow filtration has been scaled up, water treatment plant designers can now benefit from this technology for any large application,” said Marco Bosisio, vice president of Industrial Products at Neptune Benson. “Our first H2F Vortisand in France proves that crossflow microsand submicron filtration technology offers a cost-effective solution to industrial filtration challenges worldwide.”
