Selective Removal and Recovery of Phosphate from Municipal Wastewater
ISBN: 9783843382670 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Eutrophication of global water bodies, primarily due to influx of nitrogen and phosphorus in the waterways has been a concern over the past few decades. Phosphorus being the rate-limiting nutrient in freshwater ecosystems, its discharge by wastewater treatment facilities are being increasingly limited. However,current physicochemical and biological treatment methods suffer from the drawbacks of excessive sludge production, high operating costs and inability to attain complete nutrient removal due to thermodynamic and kinetic limitations. On the other hand, the global reserve of phosphate...

Hydroinformatics: Subsurface Flow and Transport
ISBN: 9783843388795 / Angielski / Miękka / 80 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Density-driven flow is the flow that is mainly influenced by the density differences in the fluid system. An example of such a flow is submarine groundwater discharge where freshwater is discharged into the sea in the form of submarine springs. Discharges from such seeps can have considerable impact on the quality of the water in the surrounding areas. As a result there is considerable interest in modelling such phenomena. In the current study, an attempt at developing a numerical model able to simulate density driven flow using the finite volume formulation has been made. The model has been...
