The intensive development of industry, the growth of cities and other settlements, and their improvement require solving the issue of preventing the negative impact of human activities on the environment. This particularly concerns the food and processing sectors, which are among the strategic pillars designed to ensure a sustainable provision of the population with the high-quality food required. Water resources rank first by the intensity of the negative impact of food and processing industry on the environment. To eliminate or reduce the damage caused to the environment by industrial waste emissions, it is proposed to switch them to closed cycles. This would allow not only solving the environmental protection issue but also rationally using natural resources. Wastewater contains feed residues, cooking salt, detergents, nitrites, phosphates, alkalis, acids, and possibly, pathogenic microflora. The paper describes a rational technology developed for the neutralization and deep purification of agricultural wastewater.
