In this research, an experimental study to evaluate nutrient removal from synthetic wastewater by a lab-scale moving bed biofilm process was investigated. Also, kinetic analysis of the process with regard to phosphorus and nitrogen removal was studied with different mathematical models. For nutrient removal, the moving bed biofilm process was applied in series with anaerobic, anoxic and aerobic...

Phosphorus-modified phosphonoacetate and thiophosphonoacetate oligodeoxyribonucleotides were chemically synthesized and their biochemical properties evaluated. Under physiological pH, these DNA analogs possess negative charge and form stable, complementary A-like DNA:RNA heteroduplexes when analyzed via circular dichroism spectroscopy. Phosphonoacetate and thiophosphonoacetate oligomers were fo...

The synthesis of 1,4-diamines containing the (Z)-1,4-diaminobut-2-ene subunit via a temporary phosphorus tether/RCM strategy is described. We have developed a new method utilizing phosphorus nuclei as suitable temporary tethers for the coupling of nonracemic allylic amines. This approach allows for the generation of C(2)-symmetric and unsymmetric 1,4-diamines 1-3, which may have considerable sy...

Simple model for anaerobic phosphorus release and aerobic uptake batch test was constructed based on ASM2d and analyzed with sensitivity analysis. And it was simulated with estimated parameters. The phosphorus behaviors were mainly influenced by the initial concentration of soluble COD (SA) in anaerobic condition and PHA (XPHA) in aerobic conditions, respectively. Sensitivity analysis suggested...

In general, conventional P analysis methods suffer from not only the fastidious extraction and pre-treatment procedures required but also the generally low specificity and poor resolution regarding the P composition and its temporal and spatial dynamics. More powerful yet feasible P analysis tools are in demand to help elucidating the biochemistry nature, roles and dynamics of various phosphoru...

Biological nutrient removal (BNR) technology can suffer poor performance or complete failure due to the fastidious nature of the bacteria used in the system. The bacteria involved necessitate strict operating conditions, multiple zones with one or more recycling lines, carbon source augmentation, and efficient aeration. For wastewater treatment plants receiving significant combined sewer overfl...
