In addition, in certain embodiments, the second SBBR includes an oxic phase for converting some ammonium to nitrite and, in some cases, an external carbon source is added to the wastewater under anoxic conditions to reduce the concentration of the nitrate in the wastewater. | 08-28-2014 |
20150068976 | PROCESS FOR TREATING AN EFFLUENT FOR THE PURPOSE OF BRINGING DOWN THE PHOSPHATE CONTENT THEREOF, COMPRISING A STEP OF OPTIMIZED WET HEAT TREATMENT, AND CORRESPONDING EQUIPMENT - The invention pertains to a method for treating an effluent to be treated in order to reduce its phosphates content, said method comprising a step of anoxic biological treatment of said effluent to be treated, producing a first effluent, a step of aerobic biological treatment of said first effluent, producing a second effluent, a step of recirculating at least a part of said second effluent to the inlet of said anoxic biological treatment step, a step of liquid/solid separation of at least a part of said second effluent, producing a treated effluent and a first denser effluent, a step for producing volatile fatty acids including a wet heat treatment, at a temperature of 100° C. to 350° C., for a residence time of between 10 and 180 minutes, of at least a part of said first denser effluent, a step of anaerobic biological treatment of at least a part of the effluent coming from said wet heat treatment step, and a step of recirculating at least a part of the effluent coming from said anaerobic biological treatment step to the inlet of said anoxic biological treatment step. | 03-12-2015 |
