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

Case Study: YSI Multiparameter Instruments Assist In Storm Water And Combined Sewer Overflow Monitoring
The city of Indianapolis, Indiana has been monitoring surface water quality of the White River and its tributaries since 1991. Each year the Indianapolis Office of Environmental Services (OES) collects nearly 6,000 samples from 27 locations. Two specialized programs, Continuous Dissolved Oxygen and Critical DO, are designed to collect data during periods when the potential exists for dissolved oxygen problems
