51. Fairbanks Nijhuis Protecting New Orleans 12/18/2012

    Originally constructed from the 1920s to 1949, the Gulf Intracoastal Waterway (GIWW) is one of America’s most remarkable transportation arteries. The New Orleans District U.S. Army Corps of Engineers operates and maintains the GIWW in Louisiana, and maintains its six locks for both navigation and agricultural purposes.

52. Demystifying Explosion Proof Submersible Pumps 12/18/2012

    When the discussion turns to requirements for “explosion-proof” pumps, many people rely on word of mouth, past practices or even old wives tales it seems. By Kevin Clemons

53. Easy And Trouble-Free Self Priming Centrifugal Pump Adjustments 12/18/2012

    Most manufacturers employ a semi-open impellers in their self priming centrifugal sewage and trash pump designs. While other types of impellers, (enclosed, open or recessed), are sometimes used, this type of impeller has a proven field record for clog resistance and high efficiency. By Kevin Clemons

54. The Straight Scoop On UPC/IAPMO Listed Grinder Pump Systems 12/18/2012

    At least two major sewage grinder pump manufacturers advertise their systems as having UPC/IAPMO listings. There has been some confusion as to what this listing really means. By Kevin Clemons

55. Mixing Comparison: Hydraulic Or Gas 5/10/2012

    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.

56. Advanced Wastewater Pumps Will Pay Dividends In Energy Savings For City Of Andalusia, Alabama 9/26/2011

    The sewer utility for the City of Andalusia, AL, was in line to receive stimulus funds for energy-related conservation projects, but the proposed use for replacing aging pumps at two lift stations along the municipal sewage collection system had to be fully demonstrated to be eligible. The prerequisite for eligibility required at least 30 days of documented monitoring to substantiate a guaranteed 25% reduction in electrical consumption.

57. X-PELLER Eliminates Hand Wipe Clogs With Ease 1/19/2011

    Designed to bring practicality and ease to daily, personal sanitary needs, increasingly durable disposable hand wipes have been making a mess with wastewater pump stations. By Smith & Loveless, Inc.

58. Case Study: Vortex Wastewater Pumps 12/28/2010
    Vortex pumps are primary sewerage pumps used to transport are sewerage through the wastewater treatment plant process. Because these pumps are required to handle the raw sewerage including grit and associated storm water runoff debris the abrasion rate is quite high. In this plant the pumps were lasting less than 1 year before severe abrasion caused reduction in tolerances leading to re-circulation. As the sewerage was no longer being efficiently transported to treatment the plants capacity was effectively reduced. Plant was considering replacement after 1 year a t a cost of $8,500.00.

60. Article: Expanded Use Of Split Seal Technology For Large Pumps And Agitators 12/28/2010
    New advances in split mechanical seals have expanded its application for use in both water and wastewater systems. These systems move vast amounts of fluid through pipes and tanks. Water-based fluid systems comprise the largest fluid transport systems in the world with wastewater streams being the largest. While the systems’ designs can vary by region, most use centrifugal pumps to move fluid. Many of the centrifugal pumps are very large and difficult to assemble, so they have not typically been sealed by mechanical seals which require total equipment disassembly. However, split mechanical seals have advanced so that these pumps can now be sealed without equipment disassembly.
