  • Dry Air Scrubber for Propylene Oxide

    Background For decades, Advanced Air Technologies, Inc. has been the leader in air scrubber  technology for abatement of Ethylene Oxide (EtO) emissions.   In fact, AAT, Inc. was founded in 1987 on a unique dry scrubbing, chemi-sorption process for EtO.  The result is a series of fixed bed “Safe-Cell II” dry scrubbers, consisting of the DR-490, DR-50, and ...

  • Reverse flexing as a physical/mechanical treatment to mitigate fouling of fine bubble diffusers

    Achieving energy neutrality has shifted focus towards aeration system optimization, due to the high energy consumption of aeration processes in modern advanced wastewater treatment plants. A study on fine bubble diffuser fouling and mitigation, quantified by dynamic wet pressure (DWP), oxygen transfer efficiency and alpha was carried out in Blue Plains, Washington, DC. Four polyurethane fine ...

  • The rehabilitation of 43 year old waste lagoons

    In 1967 the City of Concordia, MO built a segmented lagoon system to handle the small town’s waste requirements. The main industry in Concordia is a Tyson renderings plant, and the lagoon system was designed to also handle that plant’s final waste and water polishing requirements. The lagoon system was a relatively standard design, consisting of an 18.7 acre primary lagoon, a 5.6 acre ...

  • Eliminating sludge islands in your wastewater lagoon

    Old municipal and industrial wastewater lagoons have the tendency to build islands of sludge at various locations around the lagoon. It is most common for older lagoons to build such islands wherever wastewater enters the lagoons. Of course, this is because the solids entering the lagoon have enough weight to fall out of the water as flow velocity is reduced, so the solids pile up just after ...

  • Water mixing in waste lagoons

    Man-made lagoons have been used worldwide for the treatment of domestic and industrial wastewater, it seems, forever. All waste lagoons were first designed and thoughtfully planned considering their locations, soil makeup, and waste reduction processes prior to being implemented. The biological process of organic waste reduction is always a consideration of waste lagoon designs. There are three ...

  • How new technologies are shrinking wastewater’s hefty carbon footprint

    Wastewater treatment plants are energy hogs. A 2013 study by the Electric Power Research Institute and Water Research Foundation reported that they consumed about 30 billion kilowatt-hours of electricity per year, or about 0.8 percent of the total electricity used in the United States. Wastewater treatment’s high energy footprint is ironic because the organic matter in wastewater contains ...

  • Study: Wastewater treatment improves fish health

    A decade-long study by Canadian researchers concludes that improved water treatment benefits fish populations. University of Waterloo researchers found that within a year after an upgrade to one of the area’s municipal wastewater treatment plants, there was a 70 percent decrease in the occurrence of intersex fish in Ontario’s Grand River. Within three years there was a full recovery ...
