Lime Slaker System Reduces Operating Costs And Increases Sustainability At WTP
Lime Slaker System Reduces Operating Costs And Increases Sustainability At WTP

The West African City of Abidjan in Côte d’Ivoire has historically provided drinking water to its five million residents from water treatment plants that use hydrated lime systems. But because of the high content of carbon dioxide in the local groundwater, up to 160 ppm, setting the water to calcium carbonate equilibrium using hydrated lime was economically, operationally and environmentally challenging for the city of Abidjan.

  • Headworks Improvements Resulted In Significant Reduction Of Maintenance
    Headworks Improvements Resulted In Significant Reduction Of Maintenance

    Previously the crew at Payson WWTP wrestled with clogs that required constant attention and increased system downtimes. With the installation of the new headworks, the comparison was stark because suddenly the flow from the headworks was debris-free.

  • Plant Experiences “Phenomenal Improvement” With Fine Screen Retrofit
    Plant Experiences “Phenomenal Improvement” With Fine Screen Retrofit

    Spanish Fork WWTP utilizes the STEPSCREEN® in two identical headworks systems. The technology upgrade has made a vast difference in plant processing. Prior to the implementation of new technology, only one channel was processed.

  • Finescreen Helps Plant Operate On Cruise Control
    Finescreen Helps Plant Operate On Cruise Control

    As part of the new facility for the City of Clinton, the plant installed a new finescreen as an integral part of the operations. What they discovered was not only a reliable and durable technology but the automated feature of the system was transformational for plant operations. Read what they have to say.

  • Village Creek WRF Discovers Efficient Means To Use Scum
    Village Creek WRF Discovers Efficient Means To Use Scum Scum, the greasy substance that floats to the surface of clarifiers, gets nastier as it accumulates. Some smaller wastewater treatment plants mix their scum back into other processing streams while other larger plants treat their scum separately. The City of Fort Worth takes a unique approach in managing its scum and now turns what was once a liability into an asset.

    Pump Station’s Non-Dispersibles Problem: Solved

    Sun City, AZ, has had the same wastewater treatment plant since the '70s, along with a new, expensive problem: non-dispersible waste.

  • Monsters Protect Pump Station, Weather Storms In Scotland
    Monsters Protect Pump Station, Weather Storms In Scotland

    Pump blockages and rags are a significant barrier to energy and operational efficiencies at pump stations, causing unscheduled shut downs, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects caused by an influx of wipes and rags throughout a network of area pump stations. Engineers looked to a proven, powerful solution in the form of two JWC Environmental Channel Monster® grinders at one of their most problematic sites.
