Year of implementation: 2015-2016
Wastewater represents a great problem throughout the world and particularly in Spain, where the European Commission has observed great delays in compliance. Indeed, the EC has opened a number of procedures against the state, and has imposed sanctions for failure to treat water, as well as the implementation of inadequate treatment.
Moreover, there are numerous facilities that are not economically sustainable owing to the implementation of inadequate treatment technologies. The transfer of techniques used at larger WWTPs to smaller treatment plants has also resulted in the transfer of a number of fixed costs that cannot be borne by the small private companies or municipalities that operate these plants. Moreover, these small plants are normally located at headwater basins, which are usually areas of significant ecological value. Therefore, if the water is not adequately purified, the environmental impact is considerable, and there are frequent cases of this in the agro-food industry, due to the great diversity of livestock farms. The problem is particularly complex in the case of the pig industry.
Inappropriate use of slurry brings with it a number of serious problems:
- Social nuisance caused by foul odors and degeneration of landscape
- Nitrate pollution of surface waters and groundwater
- Health problems and unsuitability of land for use
- Management difficulties, and high organic and mineral contamination making potabilisation of urban water impossible
The FiT-WATER projects assumes the challenge of demonstrating that a water treatment technology significantly increases its value and reproducibility on pig farms, through the use of new ICTs with the capacity to mitigate environmental problems. The main aim of the project is to implement innovative techniques aimed at making treatment processes more technological and demonstrating these techniques on a pig farm in order to showcase this attractive technology for the water treatment sector in general, and in particular, for the pig sector, a market that has long been crying out for technologically efficient solutions.
The specific project objectives are as follows:
- Develop a slurry treatment plant monitoring, visualisation and control system based on FIWARE technology, in order to enable the following:
- Collection of real time information on system status at different locations (temperatures, pressures, pump status, etc)
- Analysis of historical and real time data
- An alarm and incident management system
- Smart visualisation
- Remote control of facility (activation of pumps and systems)
- Each of these subsystems uses different FIWARE tools
- Validate the use of treatment plant outputs, mainly treated water, sludge and lignin, through the following procedures:
- Selection of irrigation and/or fertirrigation doses to be applied in horticulture
- Validation of the effect of lignin as an agent to improve cultivation land
- Determination of the crop production yield subsequent to application of treatment plant outputs
- Characterisation of commercial, sanitary and nutritional quality of horticultural crops subsequent to application of treatment plant outputs
- Comparison of values for water and fertiliser consumption, production and product quality with values associated with traditional cultivation.
- Compare, in terms of energy, the current management scenario with the enhanced management scenario, and the use of biogas on pig farms, through energy audits, analysis of improvements and feasibility studies.
- Disseminate the project results and, if applicable, the environmental and economic benefits demonstrated in the target sector (pig farming), thereby enabling more effective access to the market.
The original treatment system was developed and patented by Ingeobras. It has been tested and replicated successfully, in terms of fully availing of the water to be treated, in such a way that there are no discharges of any kind.
