Currently, animal husbandry and poultry farming waste, cattle and pig manure, bird droppings are prohibited to be exported to the fields and used as fertilizer without pretreatment. The standard disinfection process is reduced to composting, which takes 3-12 months. A promising direction of intensification of animal waste processing is the creation of a specially formed pulsed high-voltage electric discharge inside the liquid volume. Under the influence of which the microbial flora – bacteria and fungi - intensively dies. Specialists of the SPA “Spiral” have developed a pilot plant for manure treatment. The test results showed that coliform and Enterobacteria, including dysentery bacillus, were completely destroyed after processing a sample of cattle manure by the EGI method.
