Nutrient removal efficiency may be system specific based on the geotextile bag size and influent flow rate.
The developed model agreed with the experimental results very well in a wide range of the influent flow rate (F) and solution concentration (C0).
Column studies were performed for different operating conditions and low influent flow rate, low influent Cr VI) concentration and higher bed depth give better adsorption.
Results are evaluated in simulations, demonstrating the robustness of the algorithm to variations in the influent flow and concentration, and dynamics not considered in the reduced order model.
We assume that the model is such that the bacterial growth rate is unknown, and the measurements and influent flow rates are disturbed.
The results of the simulation closely represent experimental observations over wide ranges of the influent flow rate, fluidized-bed height and adsorbent particle size.
High bed height, low influent flow rate, and high influent Cr VI) concentration were found to be the better condition for the adsorption of Cr VI).
Data obtained varying influent flow values and nitrate influent concentrations, confirm the potentiality of the system and show the possibility of full-scale applications.
Under the condition of sufficient carbon, the uniform influent flow distribution ratio was proposed from the standpoint of which is easy for process control, operation optimization and management.
The effects of relevant dynamic parameters, such as influent flow rate, adsorbent bed height and initial ammonium ion concentration on the adsorption of ammonium ion were examined, respectively.
The concept of influent flow distribution ratio was introduced according to the performance of the step-feed process for inflow splitting and volume distribution.
