  • 5.4.1. Nitrate in Depth

    Predicate All discussions of research papers on nitrate must be predicated with a caution. The 10 ppm of nitrate of the scientists, (the Hach test kit and the Lamotte test kit) is a 44 ppm test level of nitrate via the “normal” aquarium test kits (API aquarium test kit, the Seachem Multitest kit, the Sera…

  • Overcoming major bottlenecks in aquaponics – A practical approach (summary)

    great references on why AP is not good enough – also sectionsonnitratelevels Summary Aquaponics is the combination of fish production in aquaculture and hydroponic (soilless) production of crop plants. Despite of representing already a sustainable, innovative approach for future food production systems, aquaponics are still missing economic success and up to date major bottlenecks were…

  • Nitrification in rapid sand filter: phosphate limitation at low temperatures – unprocessed

    In winter 1995-1996 the RSF of AWS River-Lake Waterworks suffered from ammonium breakthrough. Research indicated that the nitrification was limited by stagnated growth of the nitrifying bacteria due to low phosphate concentrations at low temperatures (0-3°C). Phosphoric acid was dosed prior to the RSF (dose 35-50 μg PO43- -P.l-1) to stimulate bacteria growth. Two weeks after…
