SUMMARY:First application and market introduction of combined wastewater treatment and reuse technology for agricultural purposes
DESCRIPTION:First application and market introduction of combined wastewater treatment and reuse technology for agricultural purposes\n\n		\n	\n\n	\n		\n			RichWater\n\n		\n	\n\n	\n		\n			 \nWaste water source\nThe effluent coming from the municipal wastewater treatment plant of Algarrobo is the source of the reclaimed water. The municipal wastewater treatment plant treats wastewater originating from the 6\,284 inhabitants of Algarrobo town. The flow at the wastewater treatment plant is characterized by a high seasonal fluctuation due to the presence of tourists during the summer period. Wastewater inflow during summer is in the range of 4\,000 - 6\,000 m³/day\, while during the rest of the year is approximately 2\,000 - 4\,000 m³/day. The municipal plant is managed by the AXARAGUA\, a private-public partnership created by the ‘Mancomunidad de Municipios de la Axarquía’. Mancomunidad de Municipios de la Axarquia is a supra-municipal public body responsible for common management issues of municipalities within La Axarquia Region. \n\n		\n	\n\n	\n		\n			 \nDistribution System\nA pumping station distributes the reclaimed water from a reservoir tank placed at the MBR plant. The distribution network is made of PVC pipes. The reclaimed water is further stored in 7\,500 liters plastic tanks and there the nutrients contents are adapted so the final nutrition solution is distributed to PVC irrigation network. \n\n		\n	\n\n	\n		\n			 \nFarming system\nThe reclaimed water is used to irrigate avocados\, mangos and tomatoes. \n\n		\n	\n\n	\n		\n			 \nWaste water treatment description\nNutrient removal : Ultrafiltration is used along a membrane bioreactor whose design is adapted to maximize the presence of nitrates while complying legal requirements.\nPesticide removal : none\nDisinfection : UV disinfection and chlorination.\nSuspended solids removal : Ultrafiltration and a membrane bioreactor (UF\, MBR).\nOther \n\n		\n	\n\n	\n		\n			 \nCapacity\nThe wastewater treatment plant has a capacity of 150 m³/day. \n\n		\n	\n\n	\n		\n			 \nExtent of the agricultural beneficiaries\nThe experimental test site is less than one hectare. There is a strong involvement of the local community of irrigators\, in particular the ‘Community of Irrigators’ of Algarrobo which was established in 1879\, has a total irrigated area of 757 ha and includes 547 farmers. \n\n		\n	\n\n	\n		\n			 \nCosts\nNo clear data provided about the cost of the reclamation process. Funding was done by Horizon 2020 - Fast track to innovation. \n\n		\n	\n\n	\n		\n			 \nType of agreement\nFormal cooperation agreement with city council\, regional authorities and farmers in the region of La Axarquia. \n\n		\n	\n\n	\n		\n			 \nScientific results\nThe successful FP7 Treat&Use project is the base for the RichWater approach. The system has then been successfully applied in the test field in Southern Spain where various positive impacts (e.g. no additional fertilizer nor freshwater) could commonly be observed. \nMain results of the Treat & Use project: \n\nResults of crop production and yield are equivalent using treated waste water and clear water\nUse of alternative water source for irrigation permits to safe valuable water resources (e.g. aquifers)\nLow values of pathogens in water and fruit proof that TREAT&USE is a safe technology for waste water reuse in agriculture\nThe prototype can be up-scaled to higher production rates\, including food industry uses\nIt’s technically possible to use waste water directly from the sewer and provide it with the appropriate quality required by legislation\nThe use of waste water reduces the needs of additional fertilizer (and for the tomato crops tested in TREAT&USE\, there is no need of additional fertilizer at all)\nLow Operation and Maintenance and high automated control system allow an easy operation of the end user with relatively low annual costs\n\n  \n\n		\n	\n\n	\n		\n			 \nAdditional information\nVideo:\nhttps://www.youtube.com/watch?v=SAX1Qgj883c \nPDF:\nhttps://suwanu-europe.eu/wp-content/uploads/2019/11/22_RichWater_FACTSHEET-14_53_50.pdf
