Old sludge conditions usually cause a dark brown, thick, scummy foam. It is usually caused by the growth of Nocardia or Microthrix parvicella, both of which grow at the high MCRT/low F/M condition associated with old sludge. A treatment pressure is required to decrease the total sludge units in the system. Thus, one must increase wasting and try to remove foam from the …
ATB-CWE-Decanters are used to draw off the near-surface clear water layer at the end of a treatment cycle in an SBR plant by gravity: Individual outlet systems: flexible hoses or stainless steel pipe systems as telescope or swivel joint system. Submerged outlet below the water surface: safe retention of floating materials.
A sequencing batch reactor (SBR) is a variation of the activated sludge process. As a fill and draw or batch process, all biological treatment phases occur in a single tank. This differs from the conventional flow through activated sludge process in that SBRs do not require separate tanks for aeration and sedimentation (Kappe, 1999). SBR systems contain either two or more …

1/9/2021· In SBR, the sludge concentration gradually increased with low SVI, which was the basis of the stable nitrogen removal performance. Compared with that in SBR, the decreased MLVSS/MLSS in CSTR might resulted from the washout of biomass and the retention of inert matter due to the higher settling velocity of inert particles than bio-flocs. In phase IV, the …
