project - EIP-AGRI Operational Group
Study of the water cycle in pig farms and development of new methods for its use
Estudio del ciclo del agua en explotaciones ramaderas porcinas i desarrollo de nuevos metodos para su utilización
Objectives
This project aims to provide a solution to one of the main limitations of NDN technology, by connecting NDN systems with electrodialysis and ozonation technologies to treat the liquid effluents obtained.
Apart from recovering the solid fractions by composting, the aim is to recover the liquid effluents from livestock manure by ED treatment and ozonation, thereby obtaining a high quality water without any pollutants, salts or nutrients that could be reused on the farm itself, or used for recharging aquifers and other environmental services.
Description of the measures planned in the project
Objectives
El presente proyecto quiere dar solución a una de las principales limitaciones de la tecnología NDN, mediante el acoplo de los sistemas NDN con las tecnologías de electrodiálisis y ozonización para tratar los efluentes líquidos obtenidos.
El objetivo que se persigue, a parte de valorizar las fracciones sólidas mediante compostaje, es el de valorizar los efluentes líquidos de las deyecciones ganaderas mediante el tratado por ED y ozonización y de esta forma obtener un agua de calidad sin contaminantes, sales ni nutrientes, que pueda ser reutilizada en la misma granja o utilizarse para recarga de acuíferos y otros servicios ambientales.
Activities
The following actions will be carried out in order to achieve the aforementioned objectives:
- Operation and optimisation of the ED plant for the treatment of NDN effluent.
- Operation and optimisation of the ozonation plant for the purification of the ED permeate.
- Optimisation of the composting process of the solid fraction of slurry and NDN sludge.
- Assessment of the possible uses of the ED concentrate in fertigation.
- Assessment of compliance with regulations for discharge into river courses, industrial use and drinking water of the effluents obtained.
- Study of the technical-economic feasibility of the processes applied.
Activities
Para alcanzar los objetivos descritos se realizarán las siguientes actuaciones:
- Operación y optimización de la planta de ED para el tratado de efluente NDN.
- Operación y optimización de la planta de ozonización para la potabilización del permeado de ED.
- Optimización del proceso de compostaje de la fracción sólida del purín y de los fangos de NDN.
- Evaluación del cumplimiento de normativas de vertido a cauce, uso industrial y de agua potable de los efluentes obtenidos.
- Estudio de la viabilidad técnicoeconómica de los procesos aplicados.
Context
Osona is one of the areas most severely affected by the problem of livestock manure, and according to the Ministry of Agriculture, Livestock, Fisheries and Food, 20% of Spain's total slurry is produced in Osona. Livestock manure in Catalonia is currently managed in three main ways: direct application to fields; external management by an authorised manager; in situ composting of the slurry.
Although many improvements are being made to the treatment of the solid part of the slurry, with technologies such as composting to reduce the concentration of organic matter, biodrying to produce energy, and other techniques, none of these technologies focus on reusing the water, or involve a comprehensive system which recovers all the effluents obtained based on the concept of "zero waste".
This project aims to evaluate the technologies of electrodialysis (ED), ozonation and composting for treating the effluents obtained in NDN slurry treatment facilities. The processes of ED and ozonation could reduce the content of nutrients and salts in the effluent in NDN, and this would enable this effluent to be reused, avoiding problems of salinisation and excess nutrients in the soil.
The new technological approach will provide a compost suitable for use in agriculture and water suitable for use on farms, either for cleaning or watering for livestock. The potential application of the concentrate obtained in ED by fertigation will also be considered.
