WASTEWATER

Cutting-Edge Solutions For Coking Wastewater Reuse To Meet The Standard Of Circulation Cooling Systems

Coking wastewater generated from the processes of coking, coke gas purification, and recovery of coking products, is highly toxic and carcinogenic. The wastewater usually contains phenolic, aromatic, heterocyclic, and polycyclic organics, and some inorganics, such as cyanides, sulfides, ammonium, ammonia, and so on, which makes it hardly degradable.

    How To Control Activated Sludge With Online Sensors

    The goal for domestic wastewater treatment in the 21st century should be to have a minimal carbon footprint and to be 100% self-sustainable with regards to energy, carbon, and nutrients – while achieving a discharge or reuse quality that preserves the quality of receiving waters (Water Environment Research Foundation (WERF), 2009). Sustainability with respect to energy requires both conservation and production. By Dr. Robert Smith, Ph.D., P.E., BCEE, YSI, a Xylem brand

  • Biosphere™ Moving Bed Biological System Enabled Neptune Beach To Achieve Total Nitrogen Limits Without Additional Tanks
    Biosphere™ Moving Bed Biological System Enabled Neptune Beach To Achieve Total Nitrogen Limits Without Additional Tanks

    Nutrients from growing coastal communities threaten bio-diversity: Bio-diversity in Florida’s St. John’s River estuaries is dependent on clean water. Growth in the area’s coastal communities is adding nitrogen and phosphorous nutrients to the river through wastewater discharges.  These nutrients cause rapid growth of some organisms, limit dissolved oxygen availability to others, and upset the balance of a diverse ecosystem.  In 2005, the Florida Department of Environmental Protection began implementing Total Mass Discharge Limits (TMDL) for nitrogen and phosphorous from the area's wastewater treatment plants.

  • Total Kjeldahl Nitrogen: Simplified With s-TKN™
    Total Kjeldahl Nitrogen: Simplified With s-TKN™

    The Dallas County Water and Sewer Authority (DCWSA) in Selma, Alabama recently found itself in a tough spot: under the scrutiny of the Alabama Department of Environmental Management (ADEM). The wastewater treatment system needed better means for control. Ammonia, TSS, cBOD, and TKN readings were out of compliance. Then they discovered a new testing method known as simplified-TKN (s-TKN), and with it, better process control to achieve regulatory compliance.
