  • How To Predict And Prevent CSOs And SSOs

    Combined and sanitary sewer overflows are natural hazards for wastewater collection systems. Without a comprehensive solution to monitor troublesome conditions, overflows can be triggered with little warning and lead to expensive and embarrassing situations. Fortunately, versatile analytical systems that capitalize on existing wastewater collection infrastructure hold promise for avoiding such negative impacts.

  • A Simple, Effective Strategy For Preventing Clogs

    Municipal wastewater treatment plant operators face significant challenges from a surge in clogs. Wipes that have been marketed as flushable, but don’t necessarily break down like toilet paper, are increasingly ending up in the waste stream. The proper mechanical solutions can help mitigate the problem and make operators’ lives easier.

  • Fluence's MABR For Wastewater Treatment features Passive Aeration And Saves Up To 90% On Energy Costs

    The Bordeaux region of St. Thomas had a pressing need for a wastewater treatment plant that produces high effluent quality.

  • Precise Biogas Flow Measurement

    As oil prices remain high, we are in the midst of a nation-wide initiative to seek renewable sources of energy to increase energy efficiency and energy security. Renewable energy accounted for 13.2% of the domestically produced electricity in 2012. Among the sources of renewable energy is the production of biogas from landfill gas (LFG) or digester gas.

  • Alcoholic Beverage Fusel Alcohol Testing With Static Headspace

    A static headspace method was developed using Teledyne Tekmar automated headspace vial samplers to meet the method requirements of the Alcohol and Tobacco Tax and Trade Bureau of the US Department of the Treasury (TTB) method SSD: TM:2001 for testing fusel alcohols in alcoholic beverages.

  • Dissolved Oxygen Measurement In Wastewater Treatment

    A wastewater treatment plant separates solids from the liquid, and consists of two basic stages: primary treatment and secondary treatment.

  • The Active Control Program For Advanced UV Oxidation

    This application note will explore how active control programs lower operational costs of compliant contaminant removal. 

  • Mapping And Identifying The Source Of Water Quality Issues

    A Southern U.S. municipality experiencing taste and odor issues in a certain neighborhood was also having difficulty maintaining chlorine residual levels in the area. Biological growth was suspected, however, water leaving the treatment plant met and exceeded all water quality requirements. After several investigations, the source of contamination in the distribution system could still not be identified.

  • Filter Installations Remove Solids From FGD Scrubber Effluent

    Power plants and refineries around the world must manage and treat complex effluent waste streams from the Flue Gas Desulfurization (FGD) process. Flue gas is generated by the combustion process of fossil and fossil-derived fuels, such as coal, oils, and natural gas in power plants. Petrochemical refineries may generate flue gas from a number of different processes, including Catalytic Cracking, Steam Methane Reforming, and Heaters or Furnaces.

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.
