  1. 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.

  2. 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.

  3. Pilot Testing Potassium Sulfate Crystallization 1/13/2015

    ICP’s Ochoa Mine Project is projected to produce approximately 714,000 tons per year of SOP (K2SO4) from polyhalite ore for greater than fifty years as concluded in a feasibility study.

  4. Calculated pH By Differential Conductivity Measurement In Mixtures Of Alkalizing Agents 10/21/2014

    Proper measurement of pH is a key factor of corrosion risk surveillance in water-steam cycles.

  5. Is It Time For An Intelligent Wastewater Network? 7/18/2014

    Mainland Europe has had intelligence in some of its wastewater networks for over ten years now, and some of the oldest real-time control systems in the U.S. date back to the 1980’s. So why has intelligence in the wastewater network not been more abundant?

  6. What's Next For Water Quality Sensor Trends In Wastewater? 5/1/2014

    ‘Smart’ devices have transformed nearly every aspect of our home and work life: smart phones, smart televisions, smart appliances, even smart homes. Process instrumentation for wastewater monitoring and control is no exception. The online sensors available today are far superior to versions available just 10 years ago providing more measurements more reliably, and at a reduced cost. By Patrick Higgins

  7. The Science Of Water: Analysis Lab Does More Than Just Testing 4/23/2014

    For many, the word “bureau” conquers up images of suit-clad men and women brandishing firearms and badges. But in Philadelphia, employees of another type of bureau are also protecting the public — using science.

  8. Radioactive Iodine In Wastewater Treatment Plants 3/18/2014

    Radioactive material in the environment often causes public concern or even panic. However, it is very common for wastewater treatment plants to have some radioactive material passing through the system. Radioactive material may occur naturally or through nuclear fission. Iodine-127 and Iodine-131 are the most common Iodine isotopes found in municipal biosolids, because it has a tendency to re-concentrate in the waste stream. This article will further explain the basic background of radioactive Iodine, its use, health risks, and its presence in the wastewater treatment plant.

  9. Case Study Of Swan Turbiwell Quarterly Calibrated Unit Versus Quarterly Verified Unit 3/14/2014

    This paper presents the field data collected over a twelve month period at a municipal surface water treatment plant employing traditional clarification and filtration.  The final effluent turbidity was monitored by the third party compliance turbidimeter, a Swan Turbiwell (Protocol Turbiwell) was calibrated quarterly just as the compliance turbidimeter, and a second Swan Turbiwell (Non-protocol Turbiwell) that was not calibrated.

  10. Myths And Realities: Ammonium Based Aeration Control In Wastewater 3/7/2014

    The introduction of simple, reliable, and affordable in situ sensors based on ion selective electrode (ISE) technology provides the opportunity for more advanced activated sludge control strategies. For example, aeration control using ammonium as a response variable in addition to or in place of dissolved oxygen (DO) using continuous monitoring and control instruments.
