[1] We present a conceptual approach for evaluating the biological and hydrological controls of nutrient removal in different sized rivers within an entire river network. We emphasize a per unit area biological parameter, the nutrient uptake velocity (nf), which is mathematically independent of river size in benthic dominated systems. Standardization of biological parameters from previous river...

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...

Replacing annual row crops with perennial grasses for bioenergy represents a landscape-level change in species composition, with the potential to impact annual soil nutrient removal on a regional scale. In this study we measured the concentration of ten essential nutrients in harvested material from three potential perennial bioenergy crops: Panicum virgatum L., Miscanthus giganteus, and a rees...

background: investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. the advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. th...

Wastewater is the spent or used water containing dissolved or suspended solids such as pollutants and microbes, including nutrients. The wastewater discharged into the water bodies are hazardous to environment and cause various health problems in human beings. Eutrophication is one such major environmental problem caused due to the discharge of nutrient rich wastewater into the nearby water bod...

For past so many years wetlands have served functions like providing habitat for aquatic and terrestrial plants and animals, for recreational activities and for treatment of polluted water. Both natural and constructed wetlands gave been used for treatment for wastewater from sewage, septic tanks, agricultural activities, industries, landfills and highways, etc. Treatment of wastewater in a wet...
