Wedge Wire Screens for Aquaculture and Fish Farming

Aquaculture operations depend on reliable water filtration to maintain water quality, protect fish stocks, and manage waste streams. Wedge wire screens provide non-clogging, low-maintenance filtration for intake water screening, recirculating aquaculture system (RAS) filtration, and effluent treatment. The continuous slot design ensures uniform flow distribution critical for maintaining dissolved oxygen levels, while passive intake configurations protect both aquatic life and the facility water supply.

APPLICATIONS

Where Our Screens Work

Intake Water Screening

Passive intake screens prevent debris, algae, and wild fish from entering aquaculture water supply systems. Low through-slot velocity meets environmental regulations for aquatic life protection.

Recirculating Aquaculture Systems (RAS)

Rotary drum screens and cylindrical filters provide continuous mechanical filtration in RAS loops. Automatic backwash maintains filtration capacity without interrupting fish production.

Effluent Treatment

Sieve bend and rotary screens remove suspended solids from discharge water before release. Meeting environmental discharge limits requires consistent filtration below permitted TSS levels.

Fish Egg and Fry Protection

Fine-slot screens in hatchery systems protect fish eggs and fry from mechanical damage while maintaining water circulation. Slot sizing is matched to species-specific requirements.

Waste Collection and Solids Removal

Flat panel and cylindrical screens collect feed waste and fecal solids from tank bottoms and raceways. Self-cleaning V-wire design reduces manual maintenance.
