- Reduced Corrosion Extends Sewer Life
- Eliminates Odour Treatment Costs
- Built-to-Spec for Any Size
The VFI’s patented spiral flow design eliminates odorous and corrosive gases in a unique way. It uses the wastewater’s own flow energy to suppress the turbulence which releases noxious gases. The spiral flow creates a downdraft which traps airborne gases and forces air into the sewage flow to oxidize odorous gases. By installing a Vortex drop structure, municipalities can save thousands of dollars in monthly chemical feed, air-phase treatment and maintenance costs.
HOW IT WORKS
VORTEX TOP FORM
The wastewater flows into the Vortex Top Form which directs the flow around a channel of decreasing radius. At the same time, the Vortex channel slopes downward to accelerate the wastewater to a supercritical velocity.
VORTEX DROP SHAFT
Once the flow is channeled into the smaller Drop Shaft, the velocity and centrifugal forces generated within the VFI cause the flow to hug the inside walls of the Vortex Drop Shaft. This spiraling flow creates a negative air core, which draws airborne gases down the Drop Shaft to the Energy Dissipation Pool. Frictional forces created within the Vortex Drop Shaft assist in dissipating the fluid energy.
ENERGY DISSIPATION POOL
The flow exit is submerged in the Energy Dissipation Pool at the bottom of the Vortex. Air and gases drawn down the air core are forced back through the wastewater and are reentrained into the flow. This significantly increases the dissolved oxygen concentration in the wastewater, and the re-entrained odorous compounds are then quickly oxidized.
TYPICAL PROJECT FLOW FOR A VORTEX FLOW INSERT
STEP 1: DESIGN INFORMATION FORM
Customer provides a completed Design Information Form to IPEX which assists IPEX engineers in developing a conceptual design.
STEP 2: CONCEPTUAL DESIGN
IPEX designs the unit based on the Design Information Form. IPEX provides conceptual drawings for the project and CFD analysis (where necessary). IPEX provides an engineering estimate.
STEP 3: DIMENSION SIGN-OFFS
Once the project has been bid and IPEX has received the purchase order, IPEX will send Dimension Sign-Offs to the Project Engineer and Contractor to verify that all the data is correct.
STEP 4: DETAILED DESIGN
Upon receiving the completed Dimension Sign-Offs, IPEX design engineers will begin the Detailed Design process.
STEP 5: FABRICATION
Once the Detailed Design has been completed, the fabrication of the Vortex unit will commence.
STEP 6: SHIPMENT & INSTALLATION
Once the fabrication process has been completed, the Vortex will be shipped to the jobsite along with a full set of detailed installation instructions.
