Drinking Water Application Notes

1. 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.

2. Chlorine Method For UKAS Accreditation And DWI Compliance At Welsh Water
   4/13/2017

   In 2013 the Drinking Water Inspectorate for England & Wales announced that water samples collected in England and Wales must be tested in a laboratory that meets specific standards for drinking water sampling and analysis. At the time of the new instruction, the chlorine method employed at the Welsh Water Bretton laboratory was unable to meet these requirements, notably for the prescribed limit of detection. This prompted the laboratory to investigate new analytical options for monitoring residual chlorine.

3. Application Note: YSI Real-Time Water Quality Monitoring And The IPSWATCH-EMPACT Program
   12/28/2005
   The Ipswich and Parker Rivers watersheds lie only a short distance north of Boston, MA. The first settlements in these watersheds began in the early 1600s. Since that time, residents have relied heavily on the natural resources of the Parker and Ipswich Rivers, their coastal estuaries and Plum Island Sound, which is known as the Great Marsh. This ecosystem has been designated and protected by the Commonwealth of Massachusetts as an Area of Critical Environmental Concern (ACEC).
4. UV Technology Offers Solution For Emerging Water Crisis
   2/19/2014

   Many are turning to UV as an effective barrier to enable the reuse of wastewater, for indirect reuse, and aquifer recharge.

5. 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.

6. Application Note: Desalination Plants: YSI Instruments Monitor Flow & Water Quality At Multiple Stages
   2/3/2011
   Desalination is the process of removing salt from sea water or brackish river or groundwater to make potable water. By YSI
7. Defining Drinking Water Plant Backwash Profile Using The SOLITAX™ Sc Suspended Solids And Turbidity Sensor
   6/7/2013

   Today’s drinking water plants have many challenges to meet as they produce water for a fast-growing and increasingly demanding population.

8. Application Note: Simultaneous Determination Of Total Bound Nitrogen (TNb) And Total Organic Carbon (TOC) In Aqueous Samples
   5/31/2011
   Total bound nitrogen (TN_b) consists of dissolved ammonia, nitrates, nitrites, amines, and other organic nitrogen-containing compounds. TN_b measurements represent an alternative to Total Kjeldahl Nitrogen (TKN) analysis for rapid screening of industrial wastewater, drinking water,agricultural run-off, and surface waters. By OI Analytical
9. Accurate Flowmetering For Enhanced Water Network Performance
   5/9/2017

   Being able to accurately measure both the quantity and rate of water passing through a water distribution system is crucial to gaining an informed understanding of overall efficiency. As such, achieving a measurement that is exact as possible can have a significant impact on key areas including supply planning, maintenance and resource deployment, leakage detection and rectification and the overall environment, in terms of controlling abstraction and reducing unnecessary draw on natural resources.

10. Ion Exchange Resins And Activated Carbons For Better-Tasting Water
    12/18/2013

    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.
