LIFEVERTALIM - Prevention and Integral management of high polluted effluents from Food SMES to urban sanitation systems
Spain is one of those EU countries subject to serious water scarcity and subsequent water quality problems. It also has a large fish canning industry that consumes large amounts of water during its production phases, including boiling, canning and cleaning. It moreover generates large amounts of wastewater that contain especially high levels of organic matter, fats and oils, nitrogen, phosphorus, salts and suspended solids – the organic and salt content is 15-50% higher than for urban wastewater. This makes wastewater treatment difficult, particular given that joint management is impossible due to the irregular geographical distribution of fish canning plants. Consequently, the treatment of these effluents is mainly carried out by urban Waste Water Treatment Plants (WWTPs), which are often not prepared for the correct management of these effluents; the high salt concentration inhibits efficient biological treatment. In addition, the production of canned seafood is seasonal, creating unmanageable load peaks and discharges into the sea or other water bodies. It is thus difficult to achieve the ‘good ecological and chemical status’ set for all water bodies by the Water Framework Directive (2000/60/EC). Techniques to improve management, along with efficient water use and treatment, are therefore necessary.
