Industrial films usually have the following types for use in different scenarios.

Thin-Film Composite (TFC) Membranes: TFC membranes are the most widely used in industrial RO applications. They consist of a thin polyamide layer on top of a porous support layer, providing high rejection rates for various contaminants.

Cellulose Acetate (CA) Membranes: CA membranes were one of the first types used in RO applications. They have a thicker active layer made of cellulose acetate, offering good rejection of salts but lower resistance to chlorine.

Thin-Film Nanocomposite (TFN) Membranes: TFN membranes are a newer generation of RO membranes that incorporate nanoparticles into the active layer. This technology enhances rejection rates and improves membrane performance.

Hollow Fiber Membranes: Hollow fiber membranes consist of small-diameter, tubular fibers that allow water to flow through the membrane walls. These membranes are commonly used in applications with high suspended solids or oils.

Brackish Water Membranes: Brackish water membranes are specifically designed for treating water with higher salinity levels than typical feed water. They offer higher rejection rates for salts and minerals found in brackish water sources.

High-Rejection Membranes: High-rejection membranes are designed to achieve exceptional rejection rates for specific contaminants, such as heavy metals, nitrates, or organic compounds. They are used in specialized industrial processes where stringent purity requirements are necessary.

Ultra-Low Pressure (ULP) Membranes: ULP membranes are engineered to operate at lower pressures, resulting in energy savings and reduced operational costs. They are suitable for applications where minimizing energy consumption is a priority.

These different types of industrial RO membranes are selected based on the specific water quality, feed water composition, and desired treated water specifications in various industries such as manufacturing, power generation, food and beverage, pharmaceuticals, and more.Please contact our staff for details.
