Description of the company

DEPUPORC offers the swine sector an integral slurry management system customised for your farm with the objective of water reuse.

The operating principle of the treatment plant is based on the mechanical solid-liquid separation and the subsequent treatment of the liquid effluent through patented electrocoagulation techniques and advanced oxidation to achieve the maximum utilisation of the water obtained from the manure as organic liquid fertiliser through the by-products obtained in the different phases.

The study of the farm’s liquid manure logistics allows us to determine the different balances of energy, mass and pollutants, with which we size and manufacture the necessary tailor-made plant to treat the farm’s liquid manure. We offer the farmer the construction and maintenance of these plants.

In the first phase of the system, we obtain, on the one hand, a separated solid that we can value as organic fertiliser and, on the other hand, a liquid effluent that we can valorise in ferti-irrigation systems by “pivots” or advance to the next phase of the treatment. In the second phase, we obtain a liquid effluent, microfiltered and already with reductions of macronutrients, which we can valorise in drip irrigation systems or advance to the next stage of treatment. In the last phases, we obtain liquid flows with increasing percentages of pollutants and bacteria removal until we reach the objective determined in the preliminary study.

DEPUPORC S.L. was constituted in Zaragoza in 2017 to exploit the rights of the “Patented system for the treatment of liquid manure with reduction of nitrogen and other pollutants by electrocoagulation and electro-oxidation techniques”. The company operates in the national market, both in the livestock and industrial sectors, since the technology applies to any industry with water treatment needs. The main objective of the system used in the livestock sector is the reduction of Nitrogen present in the livestock manure and, therefore, the reuse of the resulting liquid effluent, once separated from the solid and subsequently treated. This liquid effluent (water) can be used for irrigation, cleaning the establishment and even discharged into watercourses, provided its pollutants remain within the proper parameters. The reduction of nitrogen allows, in a proportional manner, to reduce of the hectares associated with the livestock farm for the application of liquid manure in the field.

Therefore, the environmental effect of the application of the system is global since it reduces the impact of the farm’s water footprint, avoids the saturation of crop fields, avoids the contamination of aquifers and reduces the emission of greenhouse gases. Finally, the separated solid, rich in organic matter, is valorised as fertiliser, thus completing the basic principle of circular economy.
