  • Manufacturer of Electrical Appliances - Case Study

    Denitrification of wastewater with electrodialysis A manufacturer of electrical appliances uses sodium nitrate solution for an electrochemical etching process. The sodium nitrate created concentrations of nitrate in the wastewater that were too high discharging in the sewage system. Options for treatment were biological denitrification or electrodialysis. After comparing both solutions, ...

  • Ojai Valley, CA – Ojai Valley Sanitary District Case Study

    The Ojai Valley Sanitary District (OVSD) wastewater treatment facility processes an average 1.8 MGD of wastewater per day which is then either reused for irrigation or discharged to the Ventura River. In 2010, the award winning treatment facility initiated a new program to further improve its treated effluent by removing nitrate concentrations to very low level. As part of the initiative, ARoNite ...

  • Rancho Cucamonga, CA – Biological Nitrate Removal Case Study

    The initial ARoNite Pilot programs of Nitrate Removal proved highly successful across several cities in California and brought promise for a full-scale denitrification solution. Around that same time, 2012 APT began to work with Cucamonga Valley Wager District (CVWD) to identify water wells within the CVWD’s service area that had been shut down and out-of-service due to severe nitrate ...

  • High frequency monitoring needed to protect UK rivers - Case Study

    The science behind nutrient pollution in rivers is still poorly understood despite the fact that nitrate and phosphate concentrations in the UK’s rivers are mostly unacceptable, although an element of uncertainty exists about what an acceptable level actually is. Key to improving our understanding of the sources and impacts of nutrient pollution is high-resolution monitoring across a broad ...

  • Application of Lab-on-a-chip Technology in Water Analysis

    The Important of Water Analysis Water analysis is essential to ensure its quality or to detect pollutants that should be removed by water treatment. However, water quality does not mean making the water suitable for human consumption; it depends on its end use. For example, completely different quality standards are applied in case of industrial water compared to those ...
