Wastewater Reuse & Polishing
Water reuse turns treated effluent into a usable resource, but downstream users and discharge limits demand consistently low suspended solids. High-flow cartridge filtration is an effective tertiary polishing barrier that captures residual particulate after biological or clarification stages.
Where in the process
A tertiary (final) polishing step after secondary treatment / clarification, before reuse or discharge. It targets residual suspended solids and turbidity, not dissolved load.
What goes wrong without adequate filtration
- Residual suspended solids that breach reuse or discharge turbidity limits
- Variable effluent quality that overwhelms an under-sized final barrier
- Fouling and abrasion of reuse pumps and distribution downstream
- Frequent change-outs and labour when many small cartridges carry the load
How it works
- 1
Take feed from secondary stage
Treated water from the biological or clarification stage enters the polishing filter as the final particulate barrier before reuse or discharge.
- 2
Capture residual particulate
The high-flow element removes residual suspended solids and turbidity so the water meets its reuse or discharge target.
- 3
Ride through quality swings
High dirt-holding absorbs peaks in effluent quality without a sudden pressure-drop spike or a breakthrough of solids.
- 4
Deliver reuse-ready water
Consistently low turbidity protects downstream reuse users and keeps discharge within turbidity limits.
Typical filtration requirements
- Reliable capture of residual suspended solids and turbidity
- High dirt-holding capacity for variable effluent quality
- Robust media that tolerate an industrial effluent matrix
- Low pressure drop across high reuse-water volumes
Why high-flow wins here
Selection & sizing factors
Sizing & selection
Tertiary polishing ratings depend on the reuse target — finer for demanding reuse, coarser as a discharge safeguard. We match media and rating to your effluent and reuse goal, and can supply the housing for a retrofit. Send us your effluent quality and target.
The right housing for this solution
A polishing housing is usually a retrofit into an existing plant, so it is configured to fit the available footprint and the connections you already have. We size the housing to the reuse flow, select a material that suits an industrial effluent matrix, and supply the matching high-flow elements. Use the housing configurator for a polishing skid or a replacement vessel.

View solutionFrequently asked questions
Can filtration alone make water reusable?
High-flow filtration removes residual particulate as a polishing step. Full reuse fitness depends on the whole treatment train; the cartridge stage is the final particulate barrier, not a complete treatment.
How is the rating chosen for reuse?
It follows the reuse target and the quality leaving your secondary stage. Tell us both and we recommend a rating and media.
Does high-flow filtration remove dissolved contaminants?
No. It is a particulate / suspended-solids barrier. Dissolved load is handled by the upstream treatment stages; the polishing filter targets turbidity and residual solids.
Can it be retrofitted into an existing plant?
Yes. We size a configurable housing to your reuse flow and available footprint and supply the matching elements — use the housing configurator to start.
The right solution for your process?
Tell us your flow rate, medium and target rating — we recommend the element and, if required, the matching housing.
