Treatment Trains for Water Reuse
Combine barriers based on the contaminants and intended reuse application.
Water-system note: treatment requirements depend on source water, intended use, equipment, permits and local rules. Real systems require qualified design, operation and laboratory verification.
What this topic covers
Combine barriers based on the contaminants and intended reuse application.
Core water-treatment ideas
Reuse trains may include biological treatment, filtration, membranes, adsorption and disinfection.
Multiple barriers can provide redundancy for important contaminant classes.
The appropriate train depends on source water and end-use requirements.
Important limits
Repeated recycling can reduce freshwater demand while concentrating some constituents.
What to monitor
A reuse project needs treatment, storage, distribution, monitoring, residuals and permit review.
Lifecycle perspective
Demand reduction and water balance should be considered alongside advanced treatment.
