  • Do More With Less: Integrating Nutrient Removal Control Improves Treatment Capacity And Efficiency
    Do More With Less: Integrating Nutrient Removal Control Improves Treatment Capacity And Efficiency

    Wastewater treatment plants (WWTP) are facing many challenges. Permits on nitrogen and phosphorus in the effluent water are progressively becoming stricter in order to protect surface waters from eutrophication. At the same time, plants are required to reduce both energy and chemical consumption and are often challenged with limited time and staff. In total, they are required to do more with less. In order to meet these challenges, a plant with a Sequencing Batch Reactor (SBR) in Green Lake, Wisconsin was upgraded with an advanced process control system – the OSCAR process performance optimizer with NURO controller.

  • New Water Turbidity Measurement Technology — The US Experience
    New Water Turbidity Measurement Technology — The US Experience

    The amount of insoluble matter present in drinking water is an essential quality indicator. Silt, sand, bacteria, spores, and chemical precipitates all contribute to the cloudiness or turbidity of water. Drinking water (DW) which is highly turbid can be unpalatable and unsafe. Consumption of even low concentrations of certain bacteria and other microorganisms can cause serious health effects. Consequently, an accurate and sensitive measurement of turbidity is vital for ensuring that drinking water is free of these contaminants.

  • Blower System Integration For Wastewater Aeration Applications
    Blower System Integration For Wastewater Aeration Applications

    The overall wastewater treatment process is complex, and each step is integral to ensuring water is properly purified. Effluent ends up in the plants, containing substances that must be removed before the water can be properly cleaned and returned for use. The range of potential contaminants is almost endless, and can include food, pulp, waste, or other substances. Afterwards, the water requires further scrubbing, with the aid of bacteria. It is in this part of the process that compressed air (ideally provided by energy-efficient rotary lobe blowers) plays a vital role.

  • How To Destroy Pathogens And Micropollutants With Ozone
    How To Destroy Pathogens And Micropollutants With Ozone

    Utilities continually face new challenges. Where treatment facilities were once expected to simply disinfect the water, they must now avoid creating disinfection byproducts during the process. New and more stringent regulations require removal of additional micropollutants and emerging contaminants. Finding the best technology to accomplish these goals can be difficult.

  • Aerobic Granular Sludge Technology Improves Wastewater Treatment While Reducing Lifecycle Costs
    Aerobic Granular Sludge Technology Improves Wastewater Treatment While Reducing Lifecycle Costs

    Activated sludge has been a cornerstone of wastewater treatment since the early 1900s. Over the years, variations of the activated sludge treatment process have surfaced. These variants were efforts to improve treatment performance or reduce capital or operating costs. A new technology, known as Nereda®, uses aerobic granular sludge to meet all those criteria.

    Water And Food: One Man’s Vision

    Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
