RO membrance 4040

About RO membrance 4040

A 4040 RO Membrane is a standard industry-size reverse osmosis element widely used in commercial and light industrial water purification systems. The numbers "4040" denote its physical dimensions: 4 inches in diameter and 40 inches in length.

These membranes are primarily engineered to filter brackish water, removing over 99% of dissolved solids, heavy metals, and organic impurities.

       Production Capacity: Typically produces around 2,400 to 2,600 Gallons Per Day (GPD) (roughly 250 Litres per hour) under optimal conditions.

       Salt Rejection Rate: Usually ranges between 99.0% to 99.7%, ensuring highly purified output water.

       Material Composition: Built using Polyamide Thin Film Composite (TFC), wrapped in a spiral-wound configuration to maximize the active filtration area.

       Pressure Requirements: Standard brackish water (BW) versions function between 150 to 300 psi, with a maximum rated limit of up to 600 psi. High-efficiency ultra-low pressure (ULP) variations are also available for energy savings.
