IWC 24-70: Drivers for Residual COD Removal at Industrial Water Resource Recovery Facilities (WRRFs)
William Celenza, Burns & McDonnell, Chicago, IL

Influent wastewater BOD:COD ratio is measured for predicting biotreatability; however, treated effluent BOD:COD ratios have not typically been used as a treatment benchmark. The merging of wastewater reuse requirements and stringent discharge criteria in some states and countries such as China have already required COD values as low as 3 times BOD values. This discussion will present residual COD removal scenarios at industrial facilities and present case study schemes to achieve increased COD removal efficiencies.

IWC 24-72: Advanced Fouling Control for Once-Through Systems Including Innovative Solutions for Monitoring, Treatment, and Optimization
Nora Eibergen, Nalco Water, an Ecolab Company, Naperville, IL

Once-through cooling water systems present unique challenges to successful water treatment. This presentation showcases how innovations in chemistry, automated monitoring and control, and a novel deposit sensing technology were implemented at a coal-fired power plant to heal the cooling lake, improve operational performance, and reduce chemistry usage by 25%.
