  1. Precipitant Savings Through Optimized Phosphate Elimination With Integrated Predictive Diagnostics
    4/18/2017

    Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks. Although being compliant with the effluent limits, the values observed fluctuate between 0.2 and 0.8 mg/L.

    Hach LDO® technology improves the efficiency of pharmaceutical plant’s wastewater treatment process, helping to protect the environment and the community.

  3. Improving Compliance Through Real-Time Phosphorus Control
    4/18/2017

    Levels of phosphorus, a chemical element that promotes organic growth, must be controlled in wastewater coming from beverage, food and dairy processing plants. Failure to control phosphorus accurately has a negative impact on water quality and can lead to large fines.

  4. DR6000 In The Brewing Industry
    4/18/2017

    Compliance and consistent high quality are two of the key goals within the beverage industry. Hach® provides support for these goals through comprehensive analyses of water and beer.

  5. RTC‐ST Reduces Polymer And Increases Biogas Production
    9/14/2015

    Hach’s off‐the‐shelf Real-Time Control System for Sludge Thickening (RTC‐ST) adjusts the sludge thickening process in real time. Thanks to the RTC-ST, a wastewater treatment plant improved thickened sludge consistency and gas production while reducing money spent on excessive polymer dosing and maintenance.

  6. How Automated Real-Time Controls Can Provide More Consistency In Wastewater Treatment Operations
    3/19/2015

    Within a wastewater treatment plant (WWTP), operators typically face an extremely wide range of different variabilities.

  7. Sensor Maintenance Made Easy With Predictive Diagnosis
    12/12/2014

    As winter sets in across the country, those trips outside to take a reading or conduct scheduled maintenance on your water quality instruments aren’t quite so invit­ing. But what if your instruments could save you the trip? Predictive diagnosis is set to become the operator’s new best friend.

  8. North Las Vegas Puts Advanced Wastewater Treatment To Work
    5/9/2014
    The North Las Vegas Water Reclamation Facility treats an average of 17 million gallons a day (MGD) of wastewater through an advanced nutrient removal process with subsequent membrane filtration. The utility’s process control enables treatment effluent exceeding typical environmental standards and allows discharge to Lake Meade, where it subsequently is withdrawn and fully treated by other facilities for drinking water distribution.
  9. City Saves Money And Energy With Real-Time Control System
    12/12/2013

    Because blowers are run continuously, energy costs associated with the aeration basin are typically the largest expense for wastewater facilities. The wastewater treatment plant in the city of Grand Rapids was looking to reduce aeration energy costs and recently upgraded the facility with a Hach Real-Time Control System. The result was a nearly $60,000 energy efficiency incentive payment from Consumers Energy, and the plant is now on track to save the city more than 735,000 kilowatt hours of electricity and $62,000 annually.

  10. Cruise Control Monitoring For Wastewater Treatment Plants
    11/22/2013

    Packaged, real-time control solutions from Hach can improve process efficiency of phosphorus control, nitrification and denitrification control, sludge thickening, and sludge dewatering for wastewater treatment plants. In this video, Katie Craig, Director of WorkFlow Solutions, explains how the real-time controllers make plant operations easier and more reliable. With instrument sensors, RTC modules, and a designated customer support team available to customers, learn how these off-the-shelf systems operate like cruise control to provide optimization through continuous measurement.
