Canister (pod) screens — clusters of cylindrical passive wedge-wire screens manifolded together to deliver high capacity where a single screen cannot pass the flow within fish-protective velocity limits.
Intake Screening for Water & Desalination Plants
A pod or canister screen groups multiple cylindrical passive wedge-wire screens onto a common manifold, multiplying capacity while keeping each element’s through-slot velocity low. Pods suit high-capacity SWRO and cooling-water intakes where a single T-screen cannot pass the required flow within the 0.15 m/s velocity limit that protects aquatic life.
Clustered passive cylinders on a manifold
Several wedge-wire cylinders share one intake, multiplying area.
A single manifold collects screened water from all elements.
Add elements to match flow without raising velocity.
Sequenced air-burst keeps every cylinder clear.
Cu-Ni / coated wire for marine durability.
Service one element while the others stay online.
| Parameter | Typical | Notes |
|---|---|---|
| Per-element velocity | ≤0.15 m/s | Held low by clustering |
| Elements | Multiple cylinders | Sized to total flow |
| Cleaning | Sequenced air-burst | Per element |
| Material | Cu-Ni / super duplex | Marine service |
| Use | High-capacity intakes | Beyond a single T-screen |

Select the regulatory standard for your country — it sets which parameters we need for a compliance-aware process assessment.
Required parameters for the chosen standard are flagged on the sample form. You can still submit a partial set and we will advise what else to test.
