Wastewater Application Notes

  1. VFD Energy Savings For Pumping Applications
    4/6/2017

    In the early days of variable frequency drive (VFD) technology, the typical application was in process control for manufacturing synthetic fiber, steel bars, and aluminum foil.

  2. Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency
    12/15/2017

    One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.

  3. 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. 

  4. Sink Or Swim: A Comparison Of Submersible And Surface Mixers For Anoxic And Anaerobic Tank Mixing
    9/18/2017

    With increasing requirements for enhanced nutrient removal, many wastewater plants are adding anoxic and/or anaerobic tanks in their secondary treatment systems. There are multiple options for enhanced nutrient removal including, but not limited to, the A2O (Anaerobic, Anoxic, Aerobic) process, the UCT or MUCT (Modified University of Cape Town) process and the Bardenpho process.

  5. Bristol-Myers Squibb Works Hard To Be A Good Neighbor
    4/18/2017

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

  6. How One Wastewater Treatment Plant Saved Time And Money Measuring Turbidity And TSS
    1/31/2012
    The wastewater treatment plant of a major corporation is designed for a population capacity of 6 million people and is considered a very large wastewater treatment plant.
  7. Determination Of Polar Pesticide Residues In Food Of Plant Origin, By And Automate QuPPe Solution
    9/29/2014

    The QuEChERS (Quick-Easy-Cheap-Effective-Rugged-Safe) sample extraction method was developed for the determination of pesticide residues in agricultural commodities.
