We are excited to share KC Water’s YouTube channel post on a “Five Year Old Fascinated By Wastewater Treatment Process”. It’s great to see this 5 year old, Damon Mertz, taking a plant tour of KCMO’s Fishing River Wastewater plant. We’re excited by Damon’s interest and look forward to this fine future wastewater treatment plant engineering professional! The link below is direct from Kansas City’s KCMOWater site:

Scum removal is an important feature for both primary and secondary clarifiers; however, specifications rarely specify agitation to help mix and efficiently transport this scum. Primary clarifier scum consists primarily of fats, oils, grease and other “modern trash” debris. Secondary clarifier scum is the biological foam or the biomass that has floated to the top due to denitrification. In a clarifier, scum removal mechanisms use skimmers that push the scum into a scum pit adjacent to the clarifier. As the pit fills with scum, primary and/or scum pumps pump the contents to the digesters.
The wastewater utility had to monthly manually vactor out the scum that accumulates from fats, oils and grease trapped in the primary scum trough which was costly, odorous and messy. The existing scum pumps would only pump out the clear liquid beneath leaving a floating scum mat that built up and needed to be vactored out.
In the scum pit, installed a Flygt compact 2.5HP submersible mixers on a timer and set to turn on prior to operation of scum pump. The fats, oils, grease (FOG) and floatables are entrained and pumped away and no more need to manually vactoring out four scum pits monthly.

A Flygt pump with N-hydraulics was installed to retrofit screw induced pumps. The Flygt’s self cleaning impeller to handle the challenging scum/debris without clogging.

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.

On November 30 and December 1, 2016 JCI Industries, Inc. hosted a training class on NOV/MOYNO Progressing Cavity Pump (PCP) systems. This course was open to JCI Environmental clients across Kansas and Western Missouri. The training was conducted by a Progressing Cavity Pump expert from NOV/Moyno.
Topics discussed included:
• A basic understanding of Progressing Cavity Pumps and Pumping Systems
• How to determine where PCPs can provide best value in applications
• The necessary steps to design, optimize, and operate a PCP system
• Pump sizing methodology to provide a successful PCP system
Identifying and understanding the components of a Progressing Cavity Pump was accomplished through disassembling and reassembling a pump with the training instructor.

JCI’s membership on Moyno’s Distributor Advisory Board met at the Greengate 340,000 sq ft manufacturing facility in Manchester, UK . The construction of a complete progressing pump cavity manufacturing facility including comprehensive automated and custom lines of machine shop and ALS rubber shop was completed in 2015. This facility was the original manufacturing plant for the Lancaster bombers in World War II.
