  • The Operation of Anaerobic Lagoons

    The operation of the anaerobic lagoon adjacent to Isfahan Wastewater Treatment Plant was studied over a 12- month period. The rate of organic loading, BOD and SS removal efficiencies and their relationships with organic reductions and ambient temperature were studied. A high correlation was found to hold among temperature, organic loading rate, and BOD 5 removal. A correlation coefficient of 87% ...


  • 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 ...

Two lagoon anaerobic digesters needed an affordable odor control system, which had to function whether the lagoons were full or empty. ...

  • Use of biocatalysts to reduce hydrogen sulfide emissions from lagoons and landfills

    Emission of odors from ponds and lagoons occurs due to aerobic and anaerobic decomposition of organic solids to release hydrogen sulfide, ammonia, and other organic by-products.  Aerobic biodegradation occurs near the water-air interface, where diffusion of oxygen occurs, while anaerobic degradation prevails mainly near the bottom of the pond or lagoon, where there is low or no dissolved oxygen ...

  • 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 ...

  • Case study - Mazzei aeration system solves lagoon odors and high maintenance problems

    The Problem: A large vegetable processing facility was experiencing problems with its lagoon surface aerators. The company’s treatment process includes a collection and screening assembly, two anaerobic stabilization ponds and a 40 million gallon aerated lagoon. The aeration lagoon is used for BOD reduction and polishing before the water is discharged to a near-by creek. Several surface ...

  • Case study - Mazzei aeration system eliminates odors from winery wastewater lagoons - Madera, CA

    The Problem: A California winery was having odor problems from its wastewater evaporation lagoons. The wash and wastewater from this facility contain large amounts of organic matter. The wastewater is collected and pumped to two main lagoons for evaporation, percolation, and sprinkler irrigation. The high organic loading results in high BOD levels, and over time, the lack of oxygen in the ...

  • A Bayesian network model for assessing natural estrogen fate and transport in a swine waste lagoon

    Commercial swine waste lagoons are regarded as a major reservoir of natural estrogens, which have the potential to produce adverse physiological effects on exposed aquatic organisms and wildlife. However, there remains limited understanding of the complex mechanisms of physical, chemical, and biological processes that govern the fate and transport of natural estrogens within an anaerobic swine ...

  • Anaerobic sewage treatment technology in Latin America: a selection of 20 years of experiences

    From the early introduction of Anaerobic Sewage Treatment, AST, technology to Latin America 20 years ago to now, the technology has become a viable alternative to provide affordable sanitation to the region. The engineering community has learned to identify and manage the main risks factors of the technology, namely: odor emissions, material corrosion, scum removal and low treatment performance ...

  • Feasibility of a flow-through treatment regime by the EOH2O™ electrolytic oxidation process to meet BOD, TSS and ammonia discharge limits from municipal facultative wastewater lagoons

    The patented EOH2O electrolytic oxidation process has been employed as a continuous batch treatment system for reduction of nutrients, TSS, odor, and pathogens in manure lagoons for several years. Due to the positive results of such applications, several Pacific Coast rural municipalities approached Aquatic Technologies to determine if a constant flow-through treatment system could be designed to ...


  • Upgrading an existing wastewater treatment plant based on an upflow anaerobic packed-bed reactor

    Upgrading a wastewater treatment plant (WWTP) may be necessary to meet the existing effluent quality and/or to meet the stricter future effluent quality requirements and/or to increase its capacity because of population growth or sewerage expansion to serve more areas. Inability to meet the existing effluent quality may result from lack of proper plant operation and maintenance, inadequate plant ...
