Let’s Turn Pumping on its Side with Flygt N-Horizontal – Join us for a Live Webinar

Contact JCI to Scedule for a Live Webinar

Unlike typical wet-well electric submersible solids-handling pump installations, dry-pit pump stations are not flooded with sewage. Since the dry-pit pump stations are typically built below grade level, the dry-pit pump station is vulnerable to flooding during an upset condition.

Protection of electrical equipment has dictated the installation of conventional vertically mounted, non-clog pump units in the dry-pit with a conventional electric motor installed at a level above grade, connected by an extended drive shaft. This design keeps the electric motors above the flood level. Maintaining of extended drive shafts, universal joints and bearings can be a mill-wright’s nightmare. Electric submersible pump have been successfully used in dry-pit installations for decades. While designed to continuously operate submerged in the pumped media in the wet-pit design, the adaptability of submersibles provides for excellent service in dry-pit installations.

The utilization of the dry-pit submersible pump has been expanded to include horizontal installation. This webinar reviews the installation modes for electric submersible pumps focusing upon dry-pit type applications. The numerous features and benefits of the horizontal dry-pit installed solids-handling pump will be provided to the attendees. An overview of successful projects of both new and retrofit of ageing pump units will be highlighted with emphasis placed upon design elements that pump station engineers need to focus upon.

Whether designing a new pumping station or a retrofit/upgrade for an ageing dry-pit pump station, current technology in submersible pump designs deliver pump station designers and users with alternatives to consider when developing designs. This webinar relates the technical benefits and savings of placing a submersible pump in horizontal dry-pit service.

Olathe KS wastewater expansion utilizes Flygt and Sanitaire equipment in Biological Nutrient Removal with Fermenter

Cedar Creek WWTP in Olathe, KS now has the first robust treatment system for nitrogen and phosphorus removal in the country, after a 1.5 million gallon per day (MGD) wastewater treatment facility expansion brought the hydraulic capacity of the plant to 5.25 MGD.  The goal of the expansion was to reduce the frequency of wet weather discharge overflow and lower the effluent nitrogen and phosphorus concentrations through biological nutrient removal (BNR).Flygt compactmixer

Xylem – Flygt submersible mixers and a Sanitaire Fine Bubble Aeration system were used in a new five-stage  BNR biological process to remove nitrogen and phosphorous.  Sanitaire’s coarse-bubble aeration system and Flygt PP pumps were used in this multi-step treatment process.

Key highlights of Olathe, KS WWTP Upgrade:

  • Capacity: Increase design from 1.5 MGD to 5.25 MGD
  • Consulting Engineer: Black & Veatch
  • Contractor: Garney (Grimm) Construction
  • Ribbon cutting: November 1, 2013
  • Energy Savings: implementing  fine bubble diffused aeration system
  • Designed for Low effluent Nitrogen & Phosphorus: Biological nutrient removal (BNR)
  • Fermenter: A key item is the WAS “fermenter” in the anaerobic zone to produce volatile fatty acids (VFA) to allow phosphorus accumulating organisms (PAO) to thrive in the anaerobic zone.
    • This allows sufficient carbon sources with VFA to allow for low total nitrogen limits with denitrification and to have VFAs remain in order to meet low phosphorus limits.
    • Without the fermenter, the denitrification process would compete for the VFAs and would not allow sufficient number or phosphorus accumulating organism (PAO).
  • Winner of a Silver Peak Performance Award from the National Association of Clean Water Agencies (NACWA)

Other JCI Equipment Highlights:

  • Siemens/Turblex Turbo Blowers with Integrally Geared Compressor
  • Andritz Centrifuge, D4LL

It was featured in Kansas Rural Water Associations, The Kansas Lifeline magazine, “Olathe Expands Cedar Creek Wastewater Treatment Facility to Provide Biological Nutrient Removal”,  November 2010.
