Using an adaptive approach to the development of water purification system

Abstract

In terms of water consumption from decentralized water supply systems there are a number of problematic aspects that negatively affect water quality, especially drinking water supply, namely: lack of modern control methods and integrated water treatment systems, qualified service personnel, long logistics of components and reagents, long distances to the final water consumer, inability to respond timely to the need of control laboratory equipment calibration and the failure of units and others. Unpredictable natural or man-made factors further complicate these problematic aspects. All this and the constant changes in the requirements to water quality and technological processes, leads to the search of new, modern approaches to solving such problems and issues of uncentralized drinking water supply. Therefore, this paper analyzes the current experience of developing small autonomous water purification systems for drinking water supply, which do not require constant presence of the operator and laboratory quality control of water and can work automatically in difficult conditions. Also a rationale for technological and structural design as well as the description of adaptive water purification systems using an adaptive approach to the structure as a whole, individual units, assemblies and to the power supply of electrolytic processes, giving it adaptive properties for the use in modern drinking water treatment is provided in the paper. The adaptive function of neutralizing the manifestation of dangerous biological agents and the efficiency of the system is designed for man-made and natural emergencies and water disinfection from bacteria and viruses. The pH was chosen as the main control parameter of water quality. The system uses an effective process of synthesis by electrolytic methods of coagulant, disinfectant and destructive effects on hazardous biological agents - pulsed current with changing parameters and shape. In case a working solution changes the pH, the parameters of the pulsed load current are changed by the adaptive power supply to the most efficient one. The proposed approach and model of the system are effective and preventive and is offered as an option to improve existing water treatment systems for drinking water supply.
