Quality
Environmental
Energy
• Growing population and industry
• Climate change and draught
• Stricter regulation on discharge/withdrawal
• Water reuse incentives and mandates
• Energy to increase ~30% by 2030
• Demand for water to increase ~40%
Growing water scarcity and impairment

4. Types of Reuse
Urban Reuse
• Irrigation of parks, highway
medians, golf courses, etc.
• Commercial uses such as vehicle
washing, window washing, etc.
• Fire protection
• Dust control and concrete
production
• Toilet and urinal flushing
• Construction water
Groundwater recharge
• Aquifer reinjection
• Subsurface infiltration
• Surface infiltration
Industrial Reuse
• Cooling water
• Boiler make-up water
• Industrial process water
Agricultural reuse
Environmental and recreational
• To create, restore, and/or
enhance wetlands
• Recreational and aesthetic
impoundments eg. Ornamental
ponds
Reclaimed wastewater is an increasingly
important source of supply

11. Industrial Wastewater Reuse

12. Specifics of Industrial Wastewater Reuse
Treatment
General Considerations!
• Treatability of Wastewater or achievability of
effluent requirements is always questionable!
• Wastewater characteristics can be
completely different from one application to
next within same industrial segment

13. Specifics of Industrial Wastewater Reuse
Treatment
•
•
•
•
•
•
•
•
•
•
Extreme pH variations
Non (readily) biodegradable fractions (COD, organic N)
Nutrient deficiencies (N, P, ions)
Extremely high influent concentration (COD, N, P, etc.)
High solids concentrations (TSS, VSS)/ inert material
high temperatures
high/ low TDS
inhibitory compounds or toxic compounds
other compounds to be considered for design, e.g. sulphides
Foulants/ Scalants (colloidal material, free oil, scalants)
Piloting is an essential tool for accurate design
