Water Surge Prevention: Analysis Of Solutions And Alternatives

Water Surge could cause damage in a water conveyance system, from leaking pipes to serious breakdowns and accidents the consequences of which could lead to heavy financial costs and even loss of life.  There are various solutions that are able to prevent or reduce the damage.  It is important to know the differences between the solutions, and the advantages and disadvantages of each technology, before recommending the most suitable solution for the system.

    The Highs And Lows Of Flow Measurement

    In Feb. 2014, the Federal Bureau of Reclamation informed central California farmers that they would receive no irrigation water from the lakes, canals, and reservoirs under the Bureau’s control due to severe drought conditions. During the previous year, the farmers were only given 20 percent of their normal allocation of water.  California officials who oversee the state’s water holdings also released information that no water will be available to the farmers for irrigation. Residential users also saw severe cuts. By Rich Lowrie, Water and Wastewater Industry Manager, KROHNE, Inc.

  • Versatility Of Thermal Mass Flow Meters
    Versatility Of Thermal Mass Flow Meters

    There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.

  • The Basics: Monitoring Deionized Water
    The Basics: Monitoring Deionized Water

    Years ago, high purity water was used only in limited applications. Today, deionized (Dl) water has become an essential ingredient in hundreds of applications including: medical, laboratory, pharmaceutical, cosmetics, electronics manufacturing, food processing, plating, countless industrial processes, and even the final rinse at the local car wash.

  • The Basics: Keeping Our Water Clean Requires Monitoring
    The Basics: Keeping Our Water Clean Requires Monitoring

    Keeping the water in our lakes, rivers, and streams clean requires monitoring of water quality at many points as it gradually makes its way from its source to our oceans. Over the years ever increasing environmental concerns and regulations have heightened the need for increased diligence and tighter restrictions on wastewater quality.

  • The Basics: Testing RO Quality
    The Basics: Testing RO Quality

    Osmosis is the phenomenon of lower dissolved solids in water passing through a semi-permeable membrane into higher dissolved solids water until a near equilibrium is reached.

    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.

    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.

    On-Line Phosphorous Measurement Takes The Guesswork Out Of Alum Treatment

    Phosphorous promotes eutrophication in surface waters and helps create conditions for algal blooming and oxygen depletion. Some phosphorous removal can occur naturally in a conventional biological wastewater treatment facility, but the result is not reliably compliant with increasingly strict limits on permissible phosphate levels in effluent discharged to receiving streams, ponds and lakes. By Bob Dabkowski, Hach Company
