Water & Wastewater Treatment

What you'll learn

• Explain the multi-barrier approach and interpret Canadian drinking water guidelines, provincial licences, WSER and provincial effluent standards, and turn them into design targets.
• Model treatment units as ideal and real reactors, analyse tracer tests for T10, baffling factor and dead space, and plan hydraulic profiles, flow splitting and redundancy.
• Explain particle stability and coagulation mechanisms, select coagulant doses from jar tests including enhanced coagulation, and size rapid mix and tapered flocculation by velocity gradient.
• Compute settling velocities, size sedimentation basins by overflow rate, and compare plate settlers, ballasted flocculation and dissolved air flotation.
• Design rapid granular filters for rate, media, head loss and backwashing, and compare them with membrane filtration, including integrity testing.
• Calculate log inactivation and CT for chlorine, check ultraviolet doses, explain breakpoint chlorination, and control disinfection by-products.
• Compute lime and soda ash doses for softening, oxidant needs for iron and manganese, GAC contact time and bed life, and plan PFAS treatment and corrosion control for lead.
• Characterize municipal wastewater flows and loads, estimate peaking factors, and design screening, grit removal and primary clarification.
• Design an activated sludge process by solids retention time with Monod kinetics, compute oxygen demand and wasting, and check secondary clarifiers.
• Design biological nitrogen and phosphorus removal, including nitrification SRT, MLE recycle, chemical and biological phosphorus removal, and alternative biological processes.
• Perform solids mass balances through thickening, anaerobic digestion and dewatering, estimate biogas, and apply provincial and CFIA biosolids requirements.
• Assemble design basis reports and check a nutrient removal upgrade for volume, oxygen, alkalinity, clarifiers, solids and side streams, with risks and open items.
