Adoption of optimal wastewater treatment system for fruit and vegetable production

The food industry and agro-industrial branch produce large amount of wastewater containing organic substances in high concentrations, suspended solids and cleaning agents. For small pollutant concentrations, plants dilute wastewater to standard values. However, expensive treatment is required for most of the water production process. Adoption of the most suitable wastewater treatment scheme for a fruit and vegetable enterprise is relevant because it assumes economic benefits primarily for the enterprise. The article provides an overview of existing purification systems that are suitable for cleaning specific juices of fruit and vegetable production. Using the hierarchy analysis method in this paper, an optimal wastewater treatment system of a fruit and vegetable enterprise has been selected, the main advantage of which is the possibility of returning wastewater to production. © The Authors, published by EDP Sciences.
