Drinking Water Application Notes

  1. Comparison of UV vs. Sodium Hypochlorite (Fact Sheet)

    Hypochlorite has some significant environmental concerns associated with DBPs and residual toxicity.

  2. Network Monitors Water Quality In Shale Gas Drilling Region
    High-pressure injection of water, sand, and chemicals that fracture shale deposits deep underground to free trapped natural gas is employed by drillers tapping the Marcellus shale beds, a geologic deposit that stretches from central New York to Virginia and contains gas believed to be worth hundreds of billions of dollars.

  3. Dissolved Oxygen Measurement

    One of the most important measurements in the determination of the health of a body of water is its dissolved oxygen content. The quantity of dissolved oxygen in water is normally expressed in parts per million (ppm) by weight and is due to the solubility of oxygen from the atmosphere around us.

  4. Determination Of Pesticide Residues In Honey, By An Automated QuEChERS Solution

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

  5. Degassing Boiler Feed Water in China with 3M™ Liqui-Cel™ Membrane Contactors

    ShenLan Environment Inc. located in Shanghai, China uses 3M™ Liqui-Cel™ Membrane Contactors in their boiler feed water treatment systems. These systems realize lower operating costs with the added benefit of reducing the chemicals added to the boiler feed water.

  6. Application Note: Low-Flow Sampling Of Water Quality Parameters Used In Determining Groundwater Stability
    In April 1996, the U.S. EPA developed and published a document entitled Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures. The document states that “the most common ground water purging and sampling methodology is to purge wells using bailers or high speed pumps to remove 3 to 5 casing volumes followed by sample collection.” Adverse impacts can occur through this method affecting sample quality by increasing levels of turbidity. These problems can often be mitigated by using low-flow purging and sampling to reduce sampling-induced turbidity. By YSI
  7. Solution For Algae Blooms

    Harmsco® Filtration Products is pleased to offer a solution to the ever increasing blue-algae blooms in water sources. A multi-barrier approach is necessary to physically remove intact (algae and cyanobacteria) before they rupture in the treatment process and then remove extracellular cyanobacteria through adsorption.

  8. Water Distribution System Security Monitoring

    Ensuring safe drinking water doesn’t end when the water leaves the water treatment plant. Protecting the safety and security of drinking water from accidental or intentional contamination within the distribution system is becoming increasingly important.

  9. Pipe Repair On A Budget

    A new pipe-repair solution promises to save time and money, while also being sustainable, long-lasting, fully scalable, and safe for workers.

  10. Active Energy Control – Energy Reductions Of Up To 10% Above Standard Drives

    Energy costs continue to increase. At the same time, there is increased pressure to reduce utility bills without sacrificing operations or comfort.
