  • Can trickling filters be used in a BNR process?

    Nitrogen and phosphorus are nutrients in a wastewater treatment system. A Biological Nutrient Removal (BNR) process removes either portions of the influent total nitrogen through denitrification or portions of the influent phosphorus through anaerobic selection or both. In a BNR process, ammonia is ultimately converted to nitrogen gas, not just nitrate or nitrite. If you have requirements for ...

  • Fenton degradation of Cartap hydrochloride: identification of the main intermediates and the degradation pathway

    The advanced oxidation of Cartap hydrochloride (Cartap) promoted by the Fenton system in an aqueous medium was investigated. Based on total organic carbon, chemical oxygen demand and high-performance liquid chromatography, the oxidation of Cartap is quite efficient by the Fenton system. Its long chain is easily destroyed, but the reaction does not proceed to complete mineralization. Ion ...

  • Removal of carbon dioxide from the atmosphere to reduce global warming: a modelling study

    We propose non–linear models to study the feasibility of removing CO2 from the atmosphere by introducing some external species such as liquid droplets and particulate matters in the atmosphere, which may react with this gas and get it removed by gravity. Further, this gas can also be removed by photosynthesis process upon using plantation of leafy trees around the sources of ...
