Drinking Water Application Notes

  1. Immediate pH Correction For Fluctuating Flow

    In a number of water, wastewater and industrial process applications, pH is one of the most critical and highly sensitive analytical measurements.  Examples of critical pH applications include: Reverse Osmosis (RO) systems in which a controlled feed of caustic solution is typically added to the feed stream in order to convert a portion of dissolved carbon dioxide into bicarbonate precipitate allowing for removal by the RO membrane.

  2. Accurately Measuring Network Leakage

    The pressures of supplying a growing global population mean that the world’s water supplies need to be managed more closely than ever.

  3. Ultrapure Water For Determination of Toxic Elements In Environmental Analyses

    In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using MilliporeSigma water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated.

  4. Air / Gas Mass Flow Meter Improves Wastewater Treatment Processing Efficiency

    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.

  5. Ion Exchange Resins And Activated Carbons For Better-Tasting Water

    For many, access to good-tasting tap water is limited, and buying bottled water can be expensive. Simple pour-through jug filters offer a low-cost and effective alternative. Activated carbons, in conjunction with ion exchange products, produce drinking water that is absent of all industrial pesticides and contaminants.

  6. Hydrant Pressure Monitoring Application Note

    One of the most popular uses for the Telog Hydrant Pressure Recorders (HPRs) is to monitor and analyze customer pressure complaints. The HPR is ideally suited for this application because it is rugged, highly portable, and can give a complete, time stamped picture of the pressure differential between the customer’s water pressure and the water pressure being delivered by the utility.

  7. Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications

    Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

  8. Waste Technologies Transform Problems To Profit

    Anaerobic digestion processes that radically improve the quality of wastewater while delivering green energy extracted from biological waste streams are emerging as a profitable way for agricultural and food processing industries cope with the twin impact of drought and pollution challenges.

  9. Monitoring Aromatic Organics For Optimizing Coagulation

    With the increasing awareness about the negative effects of organics within the water and wastewater treatment process along with increasingly strict water quality regulations, the need for more effective organics removal is becoming more important.

  10. A Comparative Study Of On-Line And Laboratory TOC Analyzers For Analysis Of Raw And Finished Drinking Water

    Total organic carbon (TOC) analysis is an important indicator of water quality throughout the drinking water treatment process. Raw source water is progressively treated in chemical coagulation, flocculation, sedimentation, and filtration steps to remove particulate matter and natural organic matter (NOM).
