Discharge and reuse / Application solutions

Reclaimed Water, Greywater & Rainwater Reuse

Set disinfection barriers and storage/distribution protection according to the reuse pathway and human exposure.

Illustrative wastewater treatment facility scene
Illustrative application scene

Environment and objectives

First confirm what is being treated and at which treatment stage.

Toilet flushing, washing, landscape irrigation, industrial reuse, cooling make-up and greywater/rainwater storage.

Operating conditions to check first

Different reuse pathways have different requirements. Potable reuse needs a separate specialist assessment and must not be grouped with ordinary non-potable reuse.

Compare candidate treatment approaches

Why each approach is recommended and under which conditions it applies.

01
Disinfectant

Hypochlorite and other chlorine systems matched to the intended use

Reason for recommendation
For comparison in reuse systems requiring a storage/distribution residual.
Conditions of use
Check chlorine demand, odor, corrosion and sensitivity of vegetation or downstream processes.
Documents to verify
Reuse pathway and water-quality requirements; product documents; residual/by-product monitoring
Discuss this approach
02
Disinfectant

Application-specific options such as peracetic acid and chlorine dioxide

Reason for recommendation
Assess for the specific reclaimed-water quality and disinfection contact stage.
Conditions of use
Disinfection efficacy alone is insufficient. Meet final-contact, residual and downstream requirements.
Documents to verify
Intended-use evidence; actual-water efficacy trials; residues and compatibility
Discuss this approach
03
Supporting equipment

UV, ozone and downstream storage/distribution management

Reason for recommendation
Provide validated treatment barriers for reuse systems.
Conditions of use
Water may be recontaminated between equipment discharge and the point of use. Check storage time and circulation.
Documents to verify
Equipment validation; storage/distribution flow; operational and point-of-use testing
Discuss this approach
04
Supporting products

Water-treatment support specific to the downstream use

Reason for recommendation
For reuse in cooling, membranes or irrigation, continue selection under the relevant operating conditions.
Conditions of use
Meeting disinfection requirements does not establish compliance with every process-water specification.
Documents to verify
Downstream equipment and water-quality specifications; residual compatibility; target-application information
Discuss this approach

This comparison supports initial purchasing screening. It does not replace the specific formulated product label, equipment instructions or site validation, and provides no universal dosage or on-site mixing instructions.
