The operating characteristics of six full-scale wastewater treatment plants using the staged, closed loop bioreactor process known as orbal were evaluated to determine the degree of simultaneous biological nutrient removal (SBNR) occurring. Low effluent total nitrogen concentrations indicate that simultaneous nitrification and denitrification occurs reliably in these facilities. The use of SRT ...
A pilot-scale primary maturation pond was spiked with (15)N-labelled ammonia ((15)NH(4)Cl) and (15)N-labelled nitrite (Na(15)NO(2)), in order to improve current understanding of the dynamics of inorganic nitrogen transformations and removal in WSP systems. Stable isotope analysis of delta(15)N showed that nitrification could be considered as an intermediate step in WSP, which is masked by simul...
In order to achieve satisfactory biological treatment of wastewater, the wastewater should contain sufficient carbon, nitrogen, phosphorus, and trace minerals to meet the metabolic requirements for cell growth. For most food processing wastes, nutritional balance is not a problem since there usually is enough carbon, nitrogen, phosphorus, and trace minerals. However, certain food processing was...
