Optimal Slot Sizing for Passive Intake Screens Configurable Apertures
OASIS Passive Intake Screens: Sustainable Water Withdrawal Solutions
Key Features
- Uninterrupted Operation: Designed for continuous water withdrawal from rivers, lakes, and oceans.
- Non-Plugging Vee-Wire Technology: Patented internal dual flow modifiers ensure high open area with minimal entrance velocity and pressure drop.
- Zero Submerged Moving Parts: Eliminates breakdown risks and reduces wear, paired with an air backwash cleaning system for maintenance-free performance.
Advanced Design for Environmental Protection
Our passive intake systems combine wedgewire screen structures with conveyance pipelines and pumping stations to deliver:
- Marine Biota Exclusion: Small screen apertures (typically <3 mm) and low inflow velocities (10-15 cm/s) prevent entrainment of aquatic life.
- Self-Cleaning Efficiency: Semi-automated compressed air bursts and natural water currents sweep debris and organisms off screens.
- Custom Engineering: Tailored to site-specific environmental regulations, current velocities, and ichthyoplankton protection requirements.
Technical Superiority
- Ultra-Low Velocity Design: Engineered to maintain ≤0.15 m/s slot velocity (adjustable per application), allowing juvenile fish to escape unharmed.
- Optimal Slot Sizing: Configurable apertures (2-10 mm) balance flow efficiency with regulatory compliance.
- Minimal Head Loss: Large open area and low velocities ensure energy-efficient operation across all applications.
Compliance & Durability
- 316(b) Clean Water Act Certified: Meets strict impingement/entrainment standards.
- Corrosion-Resistant Materials: Available in stainless steel, super duplex, or NSF-certified Z-Alloy.
- Proven Applications: Ideal for power plants, desalination facilities, cooling stations, and industrial water systems.
Why Choose OASIS?
- Lower Lifetime Costs: Reduced installation, operation, and maintenance expenses.
- Eco-Safe Performance: Verified fish-friendly design with <1% impingement rates.
- Scalable Solutions: High-capacity systems adaptable to any marine or freshwater environment.
