Abstract

The growth of the population of our planet, especially in cities, brings to the fore the problem of waste disposal, both solid and liquid. In the US and Europe alone, residents annually produce about 67 billion cubic meters of wastewater requiring treatment. For each type of waste, many processes and methods for their neutralization have been developed in the world practice. For wastewater treatment, bioaugmentation is currently the most common method, it is also widely used in soil bioremediation and air biofiltration. However, it should be borne in mind that there is no single component that allows cleaning from any impurities. In each individual case, it is necessary to conduct a comprehensive analysis of environmental parameters, composition of pollutants, available technologies and other conditions. And although there is no universal mechanism for bioaugmentation, the developed processes allow you to choose an algorithm for almost every specific task. But with any chosen algorithm of operation, the implementation of an automated control system should be a mandatory part of the process. Optimization of the wastewater treatment process allows not only to protect the environment, but also often leads to the efficient use of chemicals, reducing the amount of solid waste, and reducing energy consumption. Therefore, wastewater treatment plant controls used to monitor and control wastewater treatment plants are becoming absolutely essential in today’s world.
