  2. Aerobic granulation - Wikipedia

    en.wikipedia.org/wiki/Aerobic_granulation

    The feasibility study showed that the aerobic granular sludge technology seems very promising (de Bruin et al., 2004. [22] Based on total annual costs a GSBR (Granular sludge sequencing batch reactors) with pre-treatment and a GSBR with post-treatment proves to be more attractive than the reference activated sludge alternatives (6–16%). A ...

  3. Aerobic granular reactor - Wikipedia

    en.wikipedia.org/wiki/Aerobic_granular_reactor

    Aerobic granular sludge is composed of bacteria, protozoa and fungi, which allows oxygen to follow in and biologically oxidize organic pollutants. AGS is a type of wastewater treatment process for sewages and/or industrial waste treatment. [ 2 ]

  4. Activated sludge - Wikipedia

    en.wikipedia.org/wiki/Activated_sludge

    Activated sludge tank at Beckton sewage treatment plant, UK.The white bubbles are due to the diffused air aeration system. The activated sludge process is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa.

  6. Fluidized bed reactor - Wikipedia

    en.wikipedia.org/wiki/Fluidized_bed_reactor

    A fluidized bed reactor (FBR) is a type of reactor device that can be used to carry out a variety of multiphase chemical reactions. In this type of reactor, a fluid (gas or liquid) is passed through a solid granular material (usually a catalyst) at high enough speeds to suspend the solid and cause it to behave as though it were a fluid.

  7. Upflow anaerobic sludge blanket digestion - Wikipedia

    en.wikipedia.org/wiki/Upflow_anaerobic_sludge...

    Third generation UASB reactors, the ECSB reactor. This is a double layer high load system, with 2 settler layers. The upflow rates are high below the first settler layer, and low below the second settler layer - this keeps both the 'adult' and 'baby' grains in the system, which pays off in greater net growth of granular sludge.
