Fairfield-Suisun Sewer District (FSSD) in California installed a Vaughan Rotamix® hydraulic mixing system next to an identical anaerobic digester with a 7-year-old gas mixing system. Rotamix® installation was completed in Sept, 2010.

Disposable, throw-away products are making raw sewage pumping tougher than ever. The Jefferson Street Pump Station at the City of Centralia, WA had a problem demanding a cost-effective solution.

The Independence Hill Conservancy District's Taney Lift Station was having continuous problems with wipes, swiffers, and plastics deposited in the incoming lines, which then broke loose in storms and overwhelmed the old non-clog pumps.

The use of Vaughan's self-priming chopper pump and nozzles upstream of the influent screens improves plant efficiency and greatly increases the amount of cogenerated electricity from digester gas.

During 2017’s Hurricane Harvey, the wettest tropical storm on record in the United States, over 52 inches of rain fell in the Houston area. The Vaughan pumps ran continuously for 72 hours with no plugging incidents and no problems while pumping over 2.5 million gallons of unscreened sewage through the lift station. It never flooded and none of the 150 homes served by this lift station experienced sewer back-ups.

When the Otay River Pump Station had a floating blanket of grease problem, they turned to the Vaughan Chopper Pump to help eliminate it – while also being a cost-effective solution.

This project provides an unusual "before-and-after" comparison of how a high-solids loaded digester system with a Rotamix mixing system performed before and after the Foambuster was installed.

The main lift station serving the waste water treatment plant in Morgan’s Point, Texas, continually experienced problems with its three standard non-clog pumps. The pumps frequently clogged when rainfall totals reached or exceeded 2 inches. Shop rags, pieces of 2 x 4 lumber, plastic bottles, gloves, and wet wipes all commonly clogged the pumps when the standard demand increased. Pump removal, unplugging, and recurring repairs were required, but the service company was not always available for immediate assistance, causing problems for residents serviced by this lift station.

Vaughan Co. provided a 50 HP, 1750-RPM model PE4P6CS-118 vertical pedestal chopper pump for the Carnelian Bay Pump Station to replace an existing pedestal pump, which was having difficulty with ragging.  

Replacing mechanical seals twice per year was difficult and expensive for Chester, IL, but a more serious problem occurred when the seals failed with the Mississippi River at flood stage and the sealed lift station underwater.

If you go looking for a particular sewage treatment plant in Cincinnati, Ohio, the first thing you'll notice is ... you might not notice it at all. In fact, when following perfectly clear directions to the facility, you might still drive right by it, dismissing it as just another office building. It doesn't register as a treatment plant.

The Vaughan Rotamix® mixing system for the blend tank at the Salmon Creek Wastewater Treatment Plant, Vancouver, WA, should have had plenty of mixing flow for stirring up the sludge considering the relatively small size of this tank. Rotamix® is a hydraulic jet mixing system with floor-mounted nozzles powered by a Vaughan Chopper Pump. By Vaughan Company

The chopper pump is a centrifugal pump that utilizes a chopping action between the impeller and suction plate. These pumps were originally designed in the 1960s for use in the local dairy industry to transport manure to and from storage tanks.

Chopper pumps utilize a chopping action between the impeller and the suction plate to break down solids that pass through the pump into smaller pieces. Vaughan Company, an established pump manufacturer in Washington, U.S.A., designs and manufactures a line of centrifugal chopper pumps.

Vaughan Company introduces its line of Self Priming Chopper Pumps; ideally suited for lift stations, scum wells, portable cleanout, or any retrofits of clogging pumps.
