The Vortex Flow Solution – See how the technology works.

Watch our new animated video to see how the VFI’s unique patented spiral flow design eliminates odorous and corrosive gases.  The spiral flow creates a downdraft which traps airborne gases and forces air into the sewage flow to oxidize odorous gases.  Installing a Vortex drop structure can save municipalities thousands of dollars in monthly chemical feed, air-phase treatment and maintenance costs.                 Click here to download IPEX Vortex Flow Insert...

Air Entrainment and Vortex Drops

Air Entrainment and Vortex Drops

One of the most common questions from design engineers is how much air a vortex drop will inject into the sewer system.  There are often concerns that the vortex will cause significant changes in air flow in the lower sewer, or could perhaps cause it to become pressurized.  This would certainly be a valid concern if it were not for a key feature of the vortex drop – the Energy Dissipating Pool (EDP).  Without the EDP, air dragged down by the vortex could simply vent out the bottom of the structure, which would make its performance very similar to an outside drop structure with respect...

Western Regional Water Reclamation Facility Uses Vortex Flow Save Costs (Part 2)

To carry wastewater flow from customers in Boone County and portions of Kenton County to the new Western Regional Water Reclamation Facility, SD1 constructed the Western Regional Tunnel Conveyance System, an energy-saving gravity design that consists of 32,610 feet of 8.5-foot diameter pipe installed by tunneling method.  The new system has a treatment capacity of about 20 million gallons of wastewater per day is the single largest capital project in SD1’s history. To divert the flow from Dry Creek to the new plant, the force main from SD1’s Burlington Pump Station had to be rerouted...

Northern Kentucky Awarded the 2012 Environment Initiative of the Year (Part 1)

Sanitation District No. 1 (SD1) in Northern Kentucky is responsible for the collection and treatment of wastewater and storm water management covering an area of more than 220 square-miles, encompassing 30 municipalities throughout Boone, Campbell and Kenton Counties. As the second largest public sewer utility in Kentucky, SD1 is responsible for:  1,700 miles of sanitary sewer line 142 wastewater pumping stations 15 flood pump stations 8 package treatment plants 3 major wastewater treatment plants Over 400 miles of storm sewer pipe Over 28,000 storm sewer structures Over the years, SD1 has...

Ever Wondered How to Effectively Calculate Flow?

Ever Wondered How to Effectively Calculate Flow?

Here is a handy spreadsheet that was developed by Mr. Shaurav Alam, a Ph.D. candidate at Louisiana Tech University. It calculates both the Hazen Williams and Darcy Weisbach equations for flow and has a short introduction explaining both methods.  (Click on the image to download.) Accurately calculating the flow in your system is an important step when it comes to designing a Vortex Flow insert.  All wastewater systems are unique and impacted by their surrounding environment.  As a result, there are no “one size fits all” vortex flow inserts.  Instead, units are custom designed to...

WEFTEC 2012 REVIEW… “I HATE USING CHEMICALS”

This year’s WEFTEC show in New Orleans was a success. We showcased our new Vortex Flow demo unit which attracted a lot of attention from attendees and other exhibitors. “We had a few engineers stop by that have specified a Vortex in the past, but had never seen one in operation. It helped them to better understand the principles of what it can do and exactly how it works,” commented Kerry Koressel, IPEX Regional Sales Manager. For those who haven’t seen a Vortex Flow unit in action, the following video demonstrates how a typical unit operates. At WEFTEC we were able to introduce the...

How the Vortex Flow Insert Works – Part 2

The Vortex Flow PVC insert is a passive system that effectively controls H2S odors in sewer drop structures. It works by: 1) Suppressing turbulence in the flow – thus preventing H2S gas from being stripped from the sewage 2) Creates a slight negative pressure in the manhole or chamber which draws the H2S gas down and prevents it from being discharged out of the manhole. 3) Draws air into the system which oxidizes some of the airborne H2S gas 4) Entrains or oxygen into the sewage which continues to oxidize H2S in the line (effectively aerating the sewage). PERFORMANCE For H2S When the...

Overcoming Short Drops in Wet Wells

Pumping or lift stations are used to move wastewater to higher elevations from underground gravity sewer lines. Sewage is fed into, and temporarily stored in an underground pit, or wet well. When the sewage level rises to a predetermined point, a pump will start, lifting the sewage upward through a pressurized pipe system or rising main.  The sewage is then discharged into another gravity manhole and the cycle starts all over again until the sewage reaches its point of destination – usually a treatment plant.  The wet well which receives and temporarily stores the wastewater is directly...

Creating Sustainable Wastewater Systems

Sustainability is the long-term, responsible use and management of our resources both natural and manmade.  In terms of wastewater systems, there are increasing expectations relating to levels of service, protection of the environment and enhanced sustainability of the entire system.  For wastewater systems, this can be a challenging position as H2S-related odor and corrosion problems are a common occurrence in wastewater collection systems and require continuous maintenance. Several methods exist to address the problem: Chemical injection systems (for example, Ferric chloride, bioxyde)...
