Voraxial Separators

Click here to download a printable .pdf brochure EVTN’s patented Voraxial Separator (“VAS”) is a cost-efficient, continuous flow separator that simultaneously separates liquid/liquid, liquid/solid and liquid/liquid/solid mixtures flowing through the separator at heretofore unheard of high flow rates.
The Voraxial Separator is fitted with a patented, non-clog, lowshear impeller designed to create a vortex in the fluids flowing through the separator. By this action, heavier materials are forced to the outside of the vortex while lighter materials are drawn to form the central core of the vortex, thereby creating separated flow streams. A specially designed manifold is utilized at the exit of the separation chamber to collect the separated streams.
CHARACTERISTICS OF THE VORAXIAL SEPARATOR • Scaleable - The Voraxial Separator can be manufactured to handle any volume. • Clog-free - Open impeller design makes the Voraxial Separator virtually clog-free. • Low shear - Specially designed impeller produces low-shear performance. • Compact - The Voraxial Separator requires a small footprint to handle large volumes.

• Specially designed for 2-way separation (liquid/liquid and liquid/solid) and 3-way separation (liquid/liquid/solid).
• Low energy requirements. The Voraxial Separator is energy self-sufficient and provides its own motive force. The energy required to operate the Voraxial Separator is very low compared to other devices. • High flow rates and high "g" force. The Voraxial Separator is fitted with a patented, non-clog, low-shear open impeller which is capable of generating very high “G” forces at high flow rates. SEPARATOR PROPERTIES

• Separation efficiency. The Voraxial Separator effectively performs liquid/liquid, liquid/solid and liquid/liquid/solid separation as shown below. A third party concluded that: “as a separator the VAS is remarkable in its performance…"

EVTN is developing equipment to address the separation needs in the following areas:
• Crude Oil - Produced Water Separation • Oil Refinery Waste Pond Cleanup • Oil Spill Cleanup • Stormwater Management	• Headworks Grit Separation for Municipal Wastewater Treatment Plants • Palm Oil Recovery from Production Wastewaters

Enviro Voraxial Technology, Inc. is emerging as a leader in the rapidly growing environmental and industrial separation industries. EVTN has developed and patented the Voraxial Separator ("VAS"); a revolutionary and proprietary technology that efficiently separates large volumes of solids and liquids based on their distinct specific gravities. Superior separation is achieved in real-time, and in much greater volumes, with a more compact and energy efficient machine than any product on the market today. The VAS operates in-line and is capable of processing flow rates exceeding 8000 gallons per minute with only one moving part. The VAS technology helps protect the environment and its natural resources while simultaneously making countless industries more reliable, productive and cost effective.
