Water Resource Recovery Facility Replaces its Aging UV System - Murfreesboro, Tennessee (Case Study)
Water Resource Recovery Facility Replaces its Aging UV System - Murfreesboro, Tennessee (Case Study)

Significant innovation had occurred in the 17 years since the TrojanUV4000™ was installed at the Murfreesboro Water Resource Recovery Facility. Advancements associated with system efficacy, simplified maintenance, and energy efficiency had been introduced, all of which correlate to cost savings. Such advancements can all be found in the TrojanUVSigna™ – the UV system that was selected for the upgrade.

  • Do You Really Want Manual Calibration?
    Do You Really Want Manual Calibration?

    Many of us who have been around the water industry for a while can recall the days of manually calibrating online analyzers.  The arsenal would include:  a cart of tools, calibration standard, “calibrators”, and “zero sources”.  These tools would only be used a few times a year, if that.  Although the calibration of water analysis instruments should be performed on a monthly basis, most operators would admit to only calibrating them once or twice a year.

    The term wastewater can be applied to a wide range of water sources from municipal sewage to storm runoff to industrial discharge water. By Michael Sheedy, Vice President of Technology and George Di Falco, Marketing Communications, Eco-Tec Inc.

  • Improved Pump And Seal Reliability When And Where It Really Counts
    Improved Pump And Seal Reliability When And Where It Really Counts

    The City of Chester, IL was getting only about 6 months life out of the mechanical seals in their former non-clog lift station pumps. While replacing seals twice per year was difficult and expensive, the more serious problem occurred when the seals failed with the Mississippi River at flood stage and with the sealed lift station underwater.

  • Case Study: Real-time Continuous Nitrate Monitoring Provides A Window On Nutrient Loading In Lake Pontchartrain Louisiana's Lake Pontchartrain Basin lies at the mouth of the Mississippi Delta and squarely in the sights of water quality experts from around the world. The Lake Pontchartrain Basin is an esturarine system that has been significantly disturbed by the construction of the Mississippi River Gulf Outlet in the 1960s as well as agriculture, logging and development in the area. The lake's increasing salinity and shrinking wetlands have garnered significant attention, as has the nitrate-laden water rushing past the basin through the MRGO just below Pontchartrain's southern shore

    Total Kjeldahl Nitrogen: Simplified With s-TKN™

    The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.
