Product Details
The 4040 Anti Fouling RO Membrane element is engineered to deliver high-efficiency desalination while mitigating the operational challenges associated with biological, organic, and colloidal fouling. Built upon an advanced polyamide composite chemistry, the element maintains an optimal balance between water productivity and solute rejection under demanding feed conditions. Its robust physical construction ensures long-term mechanical integrity, making it a reliable component for plant operators seeking to optimize chemical consumption and extend membrane service life in commercial and industrial water treatment installations.
Core Features
- Fouling-Resistant Surface The membrane chemistry reduces the adhesion of organic matter, colloids, and suspended solids. This extends operational run times between cleanings and improves clean-in-place (CIP) efficiency.
- Consistent Water Quality With a 99.3% stabilized salt rejection (99.0% minimum), the element ensures uniform, reliable permeate quality under standard operating conditions.
- Dependable Throughput An active membrane area of 78 ft² (7.2 m²) delivers a 2250 GPD capacity, maintaining steady production rates in commercial and industrial RO systems.

Technical Notes:
●Permeate flow for individual elements may vary by ±15%.
●Active membrane area may vary by ±4%.
●Optimal salt rejection is typically achieved after 24 to 48 hours of continuous operation.
●Actual field performance depends on local feed water quality, system configuration, pressure, temperature, and recovery rates.
Applications

Frequently Asked Questions (FAQ)
Q1: How does the anti-fouling feature work?
A: The membrane surface is treated to modify its hydrophobicity and charge, which prevents organic matter, biological material, and suspended solids from adhering to the surface.
Q2: What feed water sources are suitable for this element?
A: It is ideal for municipal tap water, surface water (rivers/lakes), pretreated groundwater, and reclaimed wastewater where organic or colloidal fouling is a concern.
Q3: Is the FR4040 compatible with standard 4040 pressure vessels?
A: Yes. The element follows industry-standard 4040 dimensions and fits standard 4-inch commercial RO housings.
Q4: Can this membrane withstand aggressive chemical cleaning?
A: Yes. It tolerates a wide pH range (1–13) during CIP procedures, allowing for effective acid washes to remove scale and alkaline washes to remove organics.
Q5: How often should the membrane elements be cleaned?
A: Cleaning frequency depends entirely on the feed water quality and pretreatment efficiency. Operators should monitor system pressure drop and permeate flow; cleaning is recommended when normalized flow drops by 10% or differential pressure increases by 15%.
Q6: Do you offer OEM and private label options?
A: Yes. Custom labeling, private branding, and OEM manufacturing services are available for distributors, system integrators, and equipment manufacturers.
