Design of Sequencing Batch Reactors for Nitrification/Denitrification Author: Michael Kuznetz Sequencing Batch Reactors (SBRs) are used all over the world and have been around since the 1920s. With their growing popularity in Europe and China as well as the United States, they are being used successfully to treat both municipal and industrial wastewaters, particularly in…
Hydraulic Design of WW Lift Stations Author: Michael Kuznetz This course presents a summary of the principles of wastewater submerged centrifugal pump operations and wastewater wet well hydraulic design basics. In addition, it offers practical details of hydraulic design of lift stations such as pump sequencing, wet well clearance parameters, detention volume, minimum pump cycle…
Mercury Contamination of Groundwater from Coal Ash Author: Michael Kuznetz This course presents the so-called Mercury Phase Transformation Algorithm (MPTA) for electric utility boilers and power plants that use pulverized coal. The MPTA predicts mercury coal ash leachate concentration based on coal mercury content, coal fly ash content and flue gas sorbent injection rate. It…
Predicting Mercury Impacts to Groundwater from Coal Ash Author: Michael Kuznetz This course presents a new mathematical algorithm that defines the maximum initial mercury (HgII) concentration in groundwater leachate from a hypothetical coal combustion fly ash landfill. The algorithm was derived based on HgII Mass Law for the vadose zone of inorganic and slightly organic…
Soil Cation Exchange Capacity for Mercury Author: Michael Kuznetz This course presents the soil selectivity sequence and a cation exchange capacity (CEC) expression for mercury (II) which completes the author’s series of classes on mercury. The expression for soil mercury II can used in conjunction with the author’s Mercury Phase Transformation Algorithm (MPTA) for electric…
Air-Phase Mercury Removal Author: Michael Kuznetz This course presents the Universal Mercury Removal Efficiency Algorithm (UMREA) for electric utility boilers and power plants that use pulverized coal. UMREA, derived by the author, is an expanded and a more flexible version of the US DOE Mercury Removal Efficiency Algorithm. UMREA predicts flue gas mercury removal for…
