  2. Aerated lagoon - Wikipedia

    en.wikipedia.org/wiki/Aerated_lagoon

    There are two main types of submerged diffused aeration systems for lagoon applications: floating lateral and submerged lateral. Both these systems utilize fine or medium bubble diffusers to provide aeration and mixing to the process water. The diffusers can be suspended slightly above the lagoon floor or may rest on the bottom.

  3. Water aeration - Wikipedia

    en.wikipedia.org/wiki/Water_aeration

    Water aeration is often required in water bodies that suffer from hypoxic or anoxic conditions, often caused by upstream human activities such as sewage discharges, agricultural run-off, or over-baiting a fishing lake. Aeration can be achieved through the infusion of air into the bottom of the lake, lagoon or pond or by surface agitation from a ...

    en.wikipedia.org/wiki/Hypolimnetic_aeration

    TIBEAN systems exhibit a high degree of variability, catering to a wide range of applications. They offer oxygen inputs ranging from 1.5 to 60 kg/h, can be used at depths of 5 to 50 meters, and provide flow rates of 600 to 7500 m 3 /h. The utilization of deep-water aeration systems can serve various objectives, depending on the specific priorities.

  5. Fine bubble diffusers - Wikipedia

    en.wikipedia.org/wiki/Fine_bubble_diffusers

    The subject of bubble size is important because the aeration system in a wastewater or sewage treatment plant consumes an average of 50 to 70 percent of the energy of the entire plant. [3] Increasing the oxygen transfer efficiency decreases the power the plant requires to provide the same quality of effluent water. Furthermore, fine bubble ...

    en.wikipedia.org/wiki/Diffuser_(sewage)

    Diffusers are typically connected to a piping system which is supplied with pressurized air by a blower. This system is commonly referred to as a diffused aeration system or aeration grid. There are two main types of diffused aeration systems, retrievable and fixed grid, that are designed to serve different purposes.

  9. Coarse bubble diffusers - Wikipedia

    en.wikipedia.org/wiki/Coarse_bubble_diffusers

    Manufacturers of diffused aeration systems claim that converting from coarse bubble to fine bubble system should yield a 50 percent energy cost savings. [2] Specifically, in aeration tanks, a system that utilizes coarse bubble diffusers requires 30 to 40 percent more process air than a fine bubble diffused air system to provide the same level ...
