WASTEWATER CASE STUDIES AND WHITEPAPERS

  • Dual Mixers Overcome Stratification And Prevent Ice Formation In Concrete Tank With Baffles

    The climate in Southgate, Ontario, is considered cold and temperate with significant rainfall throughout the year. Temperatures in winter average around -10°C and can drop as low as -30°C to -40°C for brief periods of time, which can wreak havoc on the local water storage tanks and distribution piping. Read more to learn how the installation of PAX Mixers has kept the tanks free from ice and has shown an improvement in disinfectant residual levels.

  • FGD Purge Treatment In Coal-Fired Power Generation

    Stricter environmental policies and regulations worldwide are changing how industry approaches all aspects of business. Likewise, EU (European Union) environmental policies governing air, soil, and water quality have become progressively stringent.

    These policy changes affect the power industry’s balance of meeting growing European energy demands with compliance to environmental standards. In order to conform with EU standards specific for flue gas, a coalfired generation plant (at the time owned by Endesa, Italia, S.p.A.) in Monfalcone, Italy, undertook the measure of installing a state-of-the-art FGD (flue gas desulfurization) system at their facility. This system would remove SO2 (sulfur dioxide) from the emissions for the 336 MW coal-fired power station.

By E. Michael Thurman and Imma Ferrer Center for Environmental Mass Spectrometry Department of Environmental Engineering University of Colorado Boulder, CO, USA
  • Magnetic Flow Meters Improve Recycling Of Gas Well-Produced Water

    As old gas & oil fields play out, newer methods must be used to extract resources from areas where they are locked in layers of shale. One current technique is known as “fraccing,” in which high pressure water is pumped into the well shaft to “fracture” the rock layers, allowing more natural gas to escape and be collected. However, this technique poses a number of environmental problems, including contamination of water with hydrocarbons, solid particulates, and scale producing ions — making it unsuitable for reuse.

  • Aerated Biological Nitrogen Removal

    Excess ammonia in receiving waters causes algal blooms that decrease oxygen levels. For this reason, many wastewater treatment plants (WWTPs) must limit ammonia in discharge. Mike Rousey, Hach Company

LATEST INSIGHTS ON WASTEWATER

  • Our infrastructure systems have operated in managed deterioration for decades. And not surprisingly, once they deteriorate badly enough and cross over into active failure, all cost discipline disappears.
  • Every day, food scraps disappear into trash bags, are hauled away, and forgotten. But that waste could be turned into something productive.

  • Currently, water infrastructure is outdated and fragile, prone to breakages and leaks. Reactive approaches to water infrastructure are only implemented after an incident and are more expensive than simple maintenance fixes. Geotechnical Internet of Things (IoT) devices enable water and wastewater industry professionals to identify and address issues before they escalate into catastrophic events.
  • Traditional gravity sewers rely on large-diameter mains, deep trenches, and often multiple lift stations — elements that carry significant capital and restoration costs, particularly in rural or rugged terrain. To improve cost efficiency and sustainability, many municipalities are adopting decentralized collection systems such as Septic Tank Effluent Pump (STEP) systems, Septic Tank Effluent Gravity (STEG) systems, and liquid-only sewers.
  • Aeration control strategies often remain conservative and static. Blowers operate continuously, oxygen levels are maintained near maximum, and airflow rates are rarely adjusted in response to real-time biological demand. The result is widespread over-aeration — a condition that does not improve treatment performance but significantly increases operating costs.
  • Emerging state water reuse regulations are driving adoption of ozone and advanced oxidation, requiring flexible, high-performance systems to meet pathogen, trace organic, and DBP control objectives.
