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 reactor was studied. At a temperature of 32 ± 1 °C and a pH between 7.5 and 8.2, two operational experiments were performed: the first one fixed the hydraulic retention time (HRT) at 10 h and gradually ...
In this study, surfactant modified zeolite-clinoptilolite (SMZ) by CPB (cetylpyridinium bromide) was used for simultaneous removal of ammonium, nitrate and phosphate in synthetic wastewater, and ...

System S&P specializes in fixed-bed technology in the form of rotating biological contactors for the biological stage of sewage treatment. The RBC are the heart of the System S&P® system. Continuously turning about their own axis, the plane-parallel disks are slowy rotated, exposing them alternately to the substrate and the ambient air. The biofilm which forms on the biodiscs ...
