Dupont Filmtec BW30-4040: RO Membrane 2400 GPD, a 4″ x 40″ brackish water Reverse Osmosis Membrane that can provide RO quality water up to 2,400 gallons per day at a 15% recovery rate. It can operate at feed pressures ranging from 225 psi to 600 psi with 99.5% salt rejection. This element offers the highest quality water for a medium-sized water treatment system that produces less than approximately 10 GPM (2300 L/h) of permeate. This membrane element features the thickest feed spacer available in the industry today to lessen the impact of fouling as well as a fiber glassed shells
FilmTec 8040 membrane is an industrial-sized reverse osmosis (RO) element manufactured by DuPont (formerly Dow FilmTec) for large-scale water treatment systems. The “8040” designation refers to its standard dimensions: 8 inches in diameter and 40 inches in length. These membranes are used in industrial applications to purify brackish water and desalinate seawater
Brackish Water (BW)
Designed for treating tap water and water with lower salt concentrations (TDS up to 10,000 ppm).
BW30-400: A standard high-rejection, high-flow model for brackish water applications DATASHEET
a series of industrial reverse osmosis (RO) membranes manufactured by Polymex. The “8040” designation indicates the membrane’s standard size: 8 inches in diameter and 40 inches in length.
This size is intended for large-scale industrial RO plants and water treatment systems that require a high water output.
Key characteristics
Technology: The membranes are built with a Thin-Film Composite (TFC) structure, which allows for efficient filtration by using a semi-permeable barrier to remove contaminants.
High capacity: The large size of the 8040 series allows for high water output and excellent flow rates, making it suitable for industries that need a continuous, large-volume supply of purified water.
High rejection: These membranes are engineered for high salt rejection and effective removal of dissolved solids, organics, and other impurities.
Durability: They are known for their long operational life and resistance to fouling and scaling, which helps reduce maintenance costs.
The 4021 RO Membrane is a 4″ × 21″ thin-film composite reverse osmosis element designed for commercial and light industrial water purification systems. It delivers high-quality purified water with excellent salt rejection efficiency and stable performance. Suitable for brackish and borewell water applications, and compatible with standard 4″ membrane housings.
Key Features:
High salt rejection (up to 98–99%)
Consistent permeate flow output
Long service life with proper pre-treatment
Fits standard 4″ × 21″ RO membrane housings
Applications: Commercial RO plants, drinking water units, industrial water treatment, hotels, schools, and bottling units.
Toray 8040 Membrane is a Reverse osmosis (RO) membrane used in water purification process, these are semi permeable membranes which separate ions, unwanted molecules and larger particles from processed water. Permeate water is forced through these membranes with the use of pressure built in with the help of a pumping system.
