Mechanical Filtration
High-capacity drum and micro-screen filtration for reliable solids removal in commercial RAS loops.
What Problem It Solves
Accumulated solids increase ammonia production, consume oxygen, and harbor pathogens. Effective mechanical filtration is the first defense for stable water quality.
Position in a RAS Flow
Located immediately downstream of culture tanks to capture feed fines, feces, and suspended solids before biological treatment.
How It Works
Process water passes through automated drum or screen filters that capture particles above a defined micron rating. Backwash cycles remove collected solids to waste, maintaining consistent hydraulic performance.
Key Design Considerations
- •Match screen mesh to species and feed type
- •Size for peak feed loading, not average
- •Plan backwash water and waste handling
- •Ensure redundant capacity for commercial uptime
Common Mistakes
- •Undersizing filters for peak biomass periods
- •Ignoring backwash water recovery impact
- •Placing filtration too far from tanks increasing breakdown of solids
