Effect of salinity variation on the autotrophic kinetics of the start-up of a membrane bioreactor and hybrid moving bed biofilm reactor-membrane bioreactor at low hydraulic retention time

A membrane bioreactor (MBR) and a hybrid moving bed biofilm reactor-membrane bioreactor (hybrid MBBR-MBR) for municipal wastewater treatment were studied to determine the effect of salinity on nitrogen removal and autotrophic kinetics. The biological systems were analyzed during the start-up phase with a hydraulic retention time (HRT) of 6 h, total biomass concentration of 2,500 mg L−1 in the ...

Treatment performance, nitrous oxide production and microbial community under low-ammonium wastewater in a CANON process

To investigate the characteristics of anaerobic ammonia oxidation for treating low-ammonium wastewater, a continuous-flow completely autotrophic nitrogen removal over nitrite (CANON) biofilm ...

P-Recovery Systems

Our P-recovery systems have consistently proven to offer the lowest life-cycle cost, highest efficiency, lowest capital cost, lowest operating cost, simplest operation, least maintenance and greatest plant design or retrofit flexibility. The systems convert phosphorus and ammonia into struvite (Magnesium Ammonium Phosphate hexa-hydrate - MgNH4PO4.6H²O). As wastewater is pumped through the ...
