DuPont SFP-2860 High-efficiency Ultrafiltration Membrane For Industrial water treatment
Product Overview
The DuPont™ SFP-2860 is an 8-inch, externally-fed hollow fiber ultrafiltration (UF) membrane module designed for high-flow water treatment systems . It is engineered with high-strength, hydrophilic PVDF (Polyvinylidene Fluoride) membrane fibers to ensure long service life, reliable performance, and reduced operating costs .
Key Features & Benefits:
-
High Filtration Efficiency: A nominal pore size of 0.03 µm effectively removes bacteria, viruses, and particulate matter, including colloids, providing excellent protection for downstream processes like Reverse Osmosis (RO) systems .
-
Durable Material: The PVDF hollow fiber membrane offers high mechanical strength and strong chemical resistance, ensuring a longer lifespan and stable performance even under harsh cleaning conditions .
-
External Pressure Design: This structure allows it to handle higher feed suspended solids concentrations, reducing pre-treatment requirements and minimizing backwash water volume .
-
Cost-Effective Design: The large 8-inch diameter and 51 m² effective membrane area provide an economical design for larger systems . The U-PVC membrane shell eliminates the need for expensive pressure vessels

Proper start-up of a UF system is indispensable for preparing the membranes for operational service and preventing membrane damage. Adhering to the correct start-up sequence also contributes to ensuring that the operating parameters of the system conform to the design specifications.
Before commencing the system start-up procedures, membrane pretreatment, installation of the membrane modules, instrument calibration, and other system checks should be accomplished. Kindly refer to the product technical manual.
