81. The Most Misunderstood Fact Behind Dissolved Oxygen Sensors (It's The Pressure, Not The Concentration) 8/5/2015

    A dissolved oxygen sensor ought to be simple to understand. Whether it is membrane or optically based, it gives a signal that is proportional to the concentration of oxygen concentration in water.

82. Instant Water Quality Monitoring: It's About Time 7/6/2015

    These are trying times in the water and wastewater industry, characterized by a general lack of resources — failing infrastructure, inadequate funding, and even a lack of water itself. But it’s also an exciting time, with new technologies guiding the way to a brighter future.

83. Smell Test: A Comparison And Ranking Of Hydrogen Sulfide Emission Factors 6/1/2015

    How bad does your wastewater treatment plant (WWTP) really smell? Researchers provide a new perspective on headworks odor control and measurement.

84. Rumors, Half-Truths, And Truths About Temperature And pH 4/6/2015

    A few months ago I received a call from an angry user who was using one of our differential probes and a controller. Embedded in the probe is a thermistor that measures temperature.

85. Coal Yard Runoff Compliance Using Actiflo® Technology 3/6/2015

    Storm water runoff from a 37-acre coal storage yard utilized as part of daily operations at an industrial site in Southwestern Pennsylvania posed a problem when the Pennsylvania Department of Environmental Protection (DEP) updated the facility’s NPDES permit.

86. Measure And Control Cyanide With The CNSolution 9310 3/2/2015

87. PPCPs: Preparing For An Uncertain Regulatory Future 2/23/2015

    As regulations tighten and technology evolves, monitoring and removing pharmaceuticals and personal care products (PPCPs) from wastewater streams becomes more complex. A laboratory information management system (LIMS) may be the key to managing this complexity.

88. Math Solutions: Simulating Jar Test Results 2/12/2015

    Water Online’s “Math Solutions” series, presented by wastewater consultant and trainer Dan Theobald (“Wastewater Dan”), instructs operators on specific math solutions for operator certification exam preparation.

89. Color, Turbidity And Philosophy 1/28/2015

    When we humans look at objects we describe them in terms of color. We say that an apple is red or a leaf is green. To us color is an attribute just as surely as the mass or dimensions of an object. But the fact is that color is a pure human construct. Take away the human and it does not exist.
