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.
