  • Adaptive neuro-fuzzy inference system for real-time monitoring of integrated-constructed wetlands

    Monitoring large-scale treatment wetlands is costly and time-consuming, but required by regulators. Some analytical results are available only after 5 days or even longer. Thus, adaptive neuro-fuzzy inference system (ANFIS) models were developed to predict the effluent concentrations of 5-day biochemical oxygen demand (BOD5) and NH4-N from a full-scale integrated constructed wetland ...

  • In situ Remediation of 1,4-Dioxane using Electrical Resistance Heating

    An increasing number of states are establishing enforceable 1,4-dioxane cleanup goals due to recent improvements in analytical detection methods and existing carcinogenic risk information for 1,4-dioxane. Historically, 1,4-dioxane was used as a stabilizer for chlorinated solvents, primarily 1,1,1-trichloroethane. In addition, 1,4-dioxane has been used in a broad range of products including but ...
