The Complete Course in Water and Wastewater Treatment

Explore the major methods of disinfection by detailing plain, pre, post, double, breakpoint, and super chlorination, plus dechlorination and residual chlorine management for safe water.

Understand the theory of filtration for water treatment, using sand filtration to remove suspended particles, turbidity, and microorganisms via mechanical straining, sedimentation, biological action, and electrolyte changes.

Learn about cartridge filters, including surface and depth filters, meltblown, string wound, and pleated cartridges, their housings, and how differential pressure indicates when to replace filters.

This lecture presents screening as the first unit operation in water treatment, removing rags and plastics to protect pumps, and explains inclined bar screens and their benefits.

Understand the four zones of sedimentation basins—inlet, settling, sludge, and outlet. Identify tank types by operation and shape, including fill-and-draw, continuous-flow, circular, rectangular, and hopper-bottom.

Analyze the physical characteristics of wastewater, including color, odor, turbidity, temperature, and total solids. Understand how these factors influence wastewater treatment processes and design.

Discover how moving bed biofilm reactor (MBBR) uses thousands of polyethylene biofilm carriers in an aerated tank to achieve robust, compact wastewater treatment with easy operation and no sludge recycle.

Explore the effluent treatment plant process across biological, physical-chemical, and combined models. Learn how screening, equalization, pH control, aeration, settling, and sludge handling remove contaminants from textile wastewater.

Restore reverse osmosis membrane performance through on-site cleaning in place or off-site cleaning, using low pH or high pH treatments, following membrane specs, and flushing with permeate.
