Mechanical Filters for Aquaculture — Drum & Disc Buyer's Guide
Mechanical filters remove suspended solids before biofiltration. Missed solids poison biology, foul pipes and inflate energy. Screen aperture, hydraulic load and backwash strategy define performance.

Typical applications
- RAS solids removal
- Hatchery pre-treatment
- Effluent polishing
Project sizes
- Small RAS: $30K–$200K per unit
- Mega RAS: $500K–$5M per filter set
Selection criteria
- Screen aperture (10–100 µm) matched to solids profile
- Hydraulic load and turndown
- Backwash water consumption
- Automation and alarms
Questions buyers should ask
- Guaranteed TSS removal at my flow?
- What is backwash water as % of throughflow?
- How is the panel cleaned during CIP?
Common procurement mistakes
- Sizing on average flow, not peak
- Choosing aperture too coarse for downstream biofilter
RFQ recommendations
- Publish design TSS and hydraulic load, not model number
