Hydranautics CPA5 LD 8" Brackish Water Reverse Osmosis Membrane | KnappRO

Hydranautics CPA5-LD 8" Reverse Osmosis Membrane: High-Performance Brackish Water Filtration

The Hydranautics CPA5-LD 8" membrane is engineered for demanding brackish water treatment applications, offering exceptional efficiency in industrial, municipal, and commercial systems. With a permeate flow of 11,000 GPD (gallons per day) and a 99.7% nominal salt rejection rate, this low-fouling spiral wound element ensures maximum productivity while minimizing maintenance.

Technical Specifications

• Permeate Flow: 11,000 GPD (41.6 m³/day)
• Nominal Salt Rejection: 99.7% (minimum 99.6%)
• Membrane Type: Low-fouling spiral wound, composite polyamide
• Active Membrane Area: 400 ft² (37.1 m²)
• Element Size: 8" diameter × 40" length (8040)
• Maximum Operating Pressure: 600 psig (4.16 MPa)
• Maximum Operating Temperature: 113°F (45°C)
• Chlorine Tolerance: < 0.1 ppm
• pH Range (Continuous Operation): 2 – 11
• Feed Water SDI: ≤ 5.0

Key Features and Benefits

• High Salt Rejection: Removes up to 99.7% of dissolved salts, ideal for moderate salinity water (2,000–8,000 ppm TDS).
• Low-Fouling Design: Spiral wound construction reduces fouling, extending membrane life and lowering operational costs.
• Energy Efficiency: Operates at lower pressures, saving on energy for large-scale setups like boiler feed or cooling towers.
• Durable Build: Proven in harsh environments, with a long service life for reliable performance.

Applications

Perfect for:

• Industrial water purification in manufacturing and power plants.
• Municipal systems for potable water production.
• Agricultural irrigation and food/beverage processing.
