  • Winery and distillery wastewater treatment by anaerobic digestion

    ABSTRACTAnaerobic digestion is widely used for wastewater treatment, especially in the food industries. Generally after the anaerobic treatment there is an aerobic post-treatment in order to return the treated water to nature. Several technologies are applied for winery wastewater treatment. They are using free cells or flocs (anaerobic contact digesters, anaerobic sequencing batch reactors and ...

  • 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 ...

  • Case study - Covering lagoon stops odor complaints

    Problem: United Liquid Waste Recycling of Watertown, Wisconsin, recycles food and beverage waste into valuable byproducts such as fertilizer. Odors from the anaerobic treatment process needed to be stopped to enable the company to expand. Two lagoon anaerobic digesters needed an affordable odor control system, which had to function whether the lagoons were full or empty. ...

  • Case study - Wastewater lagoon cover stops odor complaints

    Problem: United Liquid Waste Recycling (ULWR) successfully recycles food and beverage waste into valuable by-products such as fertilizer. Odors from their anaerobic treatment process needed to be stopped to enable ULWR in Watertown Wisconsin to expand. Their two lagoon anaerobic digesters needed an affordable system to control odors. ULWR injects their valuable fertilizer into farm fields twice ...

  • Aerators Enhance Aerobic Digestion Process

    The city of Eden,N.C.,operates an extended aeration process designed for an average flow rate of 13.5 mgd with a mixed liquor suspended solids concentration that typically checks in about 6,000 mg/l. This high biomass concentration is necessary to provide a well-settling sludge and good effluent quality. Further, the plant influent is approximately 40% domestic wastewater and 60% industrial ...

  • Mixing To Enhance Facultative Wastewater Lagoon Treatment

    SolarBee® & GridBee® Are Leading The Way In most lagoons, sunlight causes a hard stratification at 12 to 18 inches of depth.  The top water is warmer and thick algae populations are producing supersaturated dissolved oxygen (DO).  The DO gasses off at the surface and is not readily available deeper in the pond for use by BOD-reducing bacteria. Meanwhile new ...

  • Turning waste into power

    Economic, social and environmental factors dictate the necessity to manage waste to a new level. Wastewater plants, landfills, farms and food plants are all the owners of biomass that can be digested to produce biogas and turned into power. Biogas can be burned directly in boilers for heat recovery and used for manufacturing, heating or cooling; this is the simplest method of direct biogas ...

  • Closed loop system takes manure and methane

    A CONVERSION plant in Mead, Nebraska is processing manure and methane to create ethanol and compost. According to Nebraska Governor Dave Heineman: “This plant sets a new standard for ethanol production in this state and our nation, and is an example of the innovation needed to take this industry to the next level. It lets America get its automotive fuel from the croplands of the Midwest instead ...

  • Biosolids management evaluation study for water reclamation facility, Sioux Falls, South Dakota

    The Sioux Falls Water Reclamation Facility (WRF) treats primary and secondary sludges in three primary anaerobic digesters and one secondary digester. Treated sludge is stored in lagoons until disposal by land application. Continuation of the land application process will require significant investment. The primary purpose of this study is to evaluate alternative biosolids handling and ...
