Description of the tech for sale
To achieve an optimum design of water treatment plants (WWTP), is necessary a deep knowledge of the mechanisms that take place in the activated sludge processes. The great quantity of factors that influences the performance of these processes, makes necessary the use of complex mathematical models. In fact, the large number of parameters present in the most used and accepted models makes especially difficult their correct estimation for a specific system. A possible alternative could be the parameter estimation through the adjustment by simulation of experimental data on dynamic conditions. However, this methodology has various disadvantages, as could be its inaccuracy for those parameters that present high correlation and its dependence on the experimental data hydraulic conditions. Researchers from the Universitat de València and the Universitat Politècnica de València, have developed an automated calibration device that allows the calculation of the kinetic and stoichiometric parameters for the most accepted models for activated sludge processes.
BioCalibra performs all necessary assays for calibration, as well as numerous experiments designed for the performance evaluation of the biological process as could be: determination of biodegradability of waste water, verification of the existence of toxic compounds, determination of possible interferences, or determination of potential impacts on treatment process. BioCalibra performs both the experimental tasks and the subsequent determination of calibration parameters for the mathematical models.
