8040 RO Membrane 8 Inch X 40 Inch 1 Year Warranty 10,500 GPD For Commercial & Industrial RO Water Filtration Plant

8040 RO Membrane 8 Inch X 40 Inch 1 Year Warranty 10,500 GPD For Commercial & Industrial RO Water Filtration Plant

I.Product Overview:

The HJ-FR-8040/400 is a high-performance fouling-resistant RO membrane element engineered for difficult water sources and environments prone to organic or colloidal contamination. With optimized membrane surface charge, enhanced smoothness, and improved hydrophilicity, it significantly reduces fouling adhesion and ensures longer operation cycles with excellent cleaning recovery.

II.Key Features:

1. Enhanced Anti-Fouling Capability

• Special membrane surface treatment improves hydrophilicity and minimizes attachment of colloids and organics.
• 34 mil feed spacer widens the flow channel, enhancing fouling resistance and cleanability.
• Provides stable performance under conditions with organic or colloidal fouling tendencies.

2. High Filtration Efficiency & Stable Performance

• Stable salt rejection up to 99.7%, minimum 99.5%.
• Permeate flow rate reaches 10,500 GPD (≈39.7 m³/day) per element.
• Effective membrane area of 400 ft² (37.2 m²) ensures strong productivity while maintaining high-quality permeate.

III.Technical Specifications:

Operating Limits

• Maximum operating pressure: 600 psi (4.1 MPa)
• Maximum operating temperature: 45°C (113°F)
• Free chlorine in feed water: < 0.1 ppm
• Continuous operation pH range: 2–11

Factory Configuration

Supplied with brine seal, interconnectors, and O-rings.
(Note: Some 8" internal-connection models may be supplied without a product water tube.)
