ANDROID APPLICATION FOR THE INFORMATION OF THE WASTEWATER pH NEUTRALIZATION PROCESS HUMAN OPERATOR

Abstract

The wastewater pH neutralization process from a wastewater treatment plant is one of the most important processes from a plant chemical step, having a strong nonlinearity and also a dynamic behavior. The multiple emergency situations that can occur in the pH neutralization process operating affects the biological processes with undesirable consequences on the plant emissary. So, the real-time information of a plant human operator regarding the problems that occur in the pH neutralization process is absolutely necessary for the optimal treatment process operating and problems prevention. The paper presents an Android application for real-time information of the wastewater pH human operator, application that uses React Native v.0.64 technology, PHP and MySQL languages. The developed application has a number of component modules (the authentication module, the process monitoring module and the module for real-time information (warning) of the process human operator), modules that works both on Android and iOS devices. The main advantage of the application is that it provides in real-time a detailed warning report for the process human operator, report that can be access by the operator on his Android device and used later in similar situations in order to take the best decisions. A set of simulation results related to the developed application is also presented, for different process disturbances.
