SUMMARY:Water reclamation for hydroponic system
DESCRIPTION:Water reclamation for hydroponic system\n\n		\n	\n\n	\n		\n			HypoWave\n\n		\n	\n\n	\n		\n			 \nWaste water source\nThe wastewater treatment plant Hattorf (Wolfsburg) treats 8\,000 population equivalents of urban wastewater. The wastewater treatment plant only receives urban wastewater without industrial discharger. All of the cities sewerage utilizes a separate system. The COD of the wastewater is about 890 mg O2/l. \n\n		\n	\n\n	\n		\n			 \nDistribution System\nAfter reclamation\, the distribution system can either be set up as through-flow system or as a circulation system with internal storage. Seven lettuce cultivation pipes with a length of 13 m each are connected to the distribution system. \n\n		\n	\n\n	\n		\n			 \nFarming system\nThe reclaimed water is used to irrigate a hydroponic grown lettuce crop in a greenhouse. In a hydroponic system lettuce plants are grown in an artificial or peat pot to which water and nutrients are provided by a nutrient solutions that is in contact with the plant roots. \n\n		\n	\n\n	\n		\n			 \nWaste water treatment description\nNutrient removal : none\nPesticide removal : Ozone and activated carbon\nDisinfection : Ozone and activated carbon\nSuspended solids removal : An integrated process consisting of an anaerobic/anoxic expanded granular sludge bed (EGSB) reactor and an aerobic sequencing batch reactor (SBR).\nOther \n\n		\n	\n\n	\n		\n			 \nCapacity\nThe hourly effluent of the wastewater treatment plant Hattorf is about 45 m³/h. The reclamation facility for the hydroponic system can treat 720 l/d. \n\n		\n	\n\n	\n		\n			 \nExtent of the agricultural beneficiaries\nThe hydroponic growing area is about 100 m² and consists of seven lettuce cultivation lines with a length of about 13 m. \n\n		\n	\n\n	\n		\n			 \nCosts\nFunding is done by the ministery of research. The cost of the reclaimed water isn't known. \n\n		\n	\n\n	\n		\n			 \nType of agreement\n\n		\n	\n\n	\n		\n			 \nScientific results\nScientific reports: \nBliedung\, A.\, Dockhorn\, T.\, Germer\, J.\, Fiebig\, B.\, Peters G.\, Rossmanith\, P.\, Wieland\, A.

Retrieved from http://www.isoe-publikationen.de/fileadmin/redaktion/ISOE-Reihen/dp/dp-43-isoe-2018.pdf \n\n		\n	\n\n	\n		\n			 \nAdditional information\nThe pilot plant and several case studies have shown the potential of the HypoWave process as an alternative cultivation method. With the reclaimed water of small communities of 500 and 1\,650 person equivalent\, an economic production can be achieved on 3\,600 and 6\,000 m². \nBrochure:\nhttp://www.hypowave.de/fileadmin/user_upload/Ergebnisse/Broschueren/1908_BR-ubt_hypowave-03_de_hi.pdf
