The Michigan Department of Environment, Great Lakes, and Energy offered a Drinking Water Treatment Series to drinking water operators and personnel associated with F-Class drinking water treatment plants in the State of Michigan. 

 

 

 


Session 1 - Basic Math, Rules and Regulations, and Source Water (Recorded 8/21/23, 2 Hours 12 Minutes)

This session will cover Basic Math, Rules and Regulations and source water. Basic math will cover exponents, areas, volumes, unit conversions, concentrations, logarithms, graphing, flow rates, and example problems. Rules and regulations will cover surface water treatment rules, log removal, interim enhanced surface water treatment rule, filter backwash recycling rule, long term enhanced surface water treatment rules, crypto outbreaks, and bin classifications. Source water will cover ground water, great lakes, inland lakes or impoundments, and rivers.

 


Session 2 - Coagulation, Mixing, Flocculation, and Sedimentation (Recorded 8/23/23, 3 hours 4 minutes)

This session will cover concepts of coagulation, mixing, flocculation, and sedimentation. Coagulation will cover related regulations, chemical reactions, physical properties, and monitoring performances. Mixing will cover rapid mixing designs, and mixing characteristics. Flocculation will cover conventional treatment, direct filtration, basin designs, solid contact clarifiers and stages. Sedimentation will cover basic concept, conventional basins, optimization, and sludge removal.

 


Session 3 - Coagulation Dosage Calculations, Disinfection, Fluoridation (Recorded 8/28/23, 3 hours 15 minutes)

This session will cover alum calculations, disinfection/chlorination, and fluoridation. Disinfection and chlorination will cover properties of chlorine, chlorine reactions, breakpoint chlorination, chlorine residuals, chlorine by-products, and example problems. Fluoridation will cover public health issues, forms of fluoride used for water treatment, storage and handling, common feeders, and design, how to calculate application levels, residual testing, and reporting requirements.

 


Session 4 - Filtration and Problems (Recorded 8/30/23, 2 hours 10 minutes)

This session will cover filtration mechanisms, design, types of filters, filter media designs/analysis, sieve analysis, types of media, filter bottoms, filter control methods, back washing, filter problems, media depth/growth/rounding, filter operations, and treatment techniques.

 


Session 5 - Direct Filtration, Membrane Filtration, and Lab Analysis (Recorded 9/6/23, 2 hours 54 minutes)

This session will cover direct filtration, membrane filtration, and lab analysis. Direct filtration will cover schematic, direct filtration requirements, and coagulation requirements. Membrane filtration will cover membrane characteristics, design and configuration, green material selection end basic components, basic modes of operation, direct integrity test, diagnostics, and regulations. Laboratory analysis will cover disinfectant residuals, pH, temperature, alkalinity, turbidity, and hardness.

 


Session 6 - Chemical Feed Systems (Recorded 9/8/23, 2 hours 17 minutes)

This session will cover chemical feed systems, chemical classifications, water treatment chemicals, and chemical feed systems.
