Embodiment Construction

[0057] According to an embodiment of the present invention and as figure 2 As shown in , there is a method 200 for wastewater treatment process (WWTP) control in a wastewater treatment process system such as EGSB system 100 . refer to figure 1 , a typical EGSB system 100 includes an EGSB reactor 102 , an influent conditioning tank 104 , a diversion tank 112 and an equalization tank 114 . Influent wastewater from various sources or customers 116 may be fed into the diversion pond 112 or into the equalization pond 114 . The primary purpose of the equalization tank 114 is to dampen fluctuations in the flow rate, temperature, and concentration of pollutants of the influent wastewater to maintain the operability of the downstream process. Where there are fluctuations in the parameters (pressure, flow rate, pollutant concentration, etc.) sudden change of measure. Finally, influent wastewater from customers 116 is directed to EGSB reactor 102 for treatment.

Abstract

A system for wastewater treatment process control comprising a set of measuring means arranged to obtain a dataset, the dataset comprises a plurality of process variables related to a parameter of thewastewater treatment process; a prediction module arranged to receive the dataset and predict the parameter of wastewater treatment process based on a soft sensor; a troubleshooting module arranged to compare the predicted parameter with a predetermined criterion; wherein if the predicted parameter does not satisfy the predetermined criterion; the troubleshooting module is operable to identify atleast one process variable from the plurality of process variables which causes the predicted parameter not to satisfy the predetermined criterion and determine whether the identified at least one process variable from the plurality of process variables is controllable. An optimisation module for use in a wastewater treatment system is also disclosed.

Description

technical field [0001] The present invention relates to systems and methods for process control in wastewater treatment. In particular, the system and method are suitable for, but not limited to, controlling parameters of an Expanded Granular Sludge Bed (EGSB) process and will be described in this context. Background technique [0002] The following discussion of the background to the invention is intended only to aid in the understanding of the invention. It should be appreciated that the discussion is not an acknowledgment or admission that any of the referenced material was public, known or part of the common general knowledge of those skilled in the art in any jurisdiction as at the priority date of the invention. [0003] Throughout the application, unless the context requires otherwise, the word "comprise" or conjugations such as "comprises (singular third person)" or "comprises (participle)" will be understood to mean the inclusion of a claimed integer or group of in...
