  • Tracer studies on an aerated lagoon

    The city of Palmerston North, New Zealand, has two aerated lagoons as its secondary treatment facility. Interest about treatment efficiency led to an investigation into the hydraulics in the second lagoon to determine if further optimisation was viable. A tracer study using rhodamine WT was undertaken to ascertain the stimulus response output. Samples were also taken at 24 points within the ...

  • Wastewater lagoons – a new aeration concept

    The use of wastewater treatment lagoons, or stabilization ponds, is a common practice for rural municipalities and industrial facilities. Through the years there have been numerous designs for these ‘sludge settling basins,’ ranging from facultative, partial aerated, and fully aerated systems. But the primary reason for these systems is to utilize relatively shallow earthen ponds, or ...

  • 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 ...
