To study process performance and population dynamics in activated sludge, a pilot-scale Membrane Bioreactor (MBR) was installed in a municipal wastewater treatment plant (Aubergenville, France). Since no solids losses occur in the MBR effluent, the sludge residence time (SRT) can be: i) easily...
aTo cut down the cost of ammonium removal in wastewater treatment, a great deal of work has been done on ammonium treatment processes and removal pathways. Traditional nitrification and denitrification theory had beenwidely accepted for years, with two reactors needed for the two processes separately...
Describe the negative effects of pollutants on crops, forests, and other materials. Which pollutants are mainly responsible for these effects? What are the advantages and disadvantages of aerobic wastewater treatment? Define and explain the differences between natural radioactive decay, nu...
Explain the process of purification of water. How do ions get into the water in nature? Explain how. Give a brief history of THMs and explain how they influence water treatment. Water is ubiquitous and necessary for life on our planet. Describe the numerous unique properties of water and how...
A one-year-set of measured data from a full scale wastewater treatment plant has been used to calibrate the efficiency of the adsorption and to evaluate the ability of the mathematical model to describe the measured data in both steady state and dynamic conditions. The approach lumped the ...
Nitrogen removal processMathematical simulationOptimal operationTo achieve new emission standards and enhance the denitrification of the oxidation ditch in the Handan West Sewage Treatment Plant, this research used the ASM Bio-P model based on self-made simulation software to study the optimum operation ...
Nanofiltration is used in a growing number of applications for the treatment of drinking water, wastewater, and process water. Trial-and-error is generally used to test the applicability of nanofiltration and to select the membranes. In particular for organic molecules, a model that describes ...
This work involves the presentation of a general approach to describe the gas-filled membrane absorption process by analyzing three different applications. Ammonia removal from wastewater was described in a previous work using a resistance-in-series model. In this contribution, this model has been ...
