GPD Reverse Osmosis Membrane

Description

RO Membranes

The Germicidal Core of 0.0001 Micron Water Purification

Reverse Osmosis (RO) membranes are the “heart” of any pure water system, acting as a sophisticated molecular barrier. Utilizing a Thin-Film Composite (TFC) multi-layered structure, these membranes achieve an incredibly fine filtration level of 0.0001 micron—a precision that standard filters cannot match. This allows the system to expel up to 98% of dissolved salts, heavy metals, bacteria, and viruses, providing the safest possible drinking water.

Features

• High Contaminant Rejection: Effectively removes Total Dissolved Solids (TDS), Lead, Arsenic, Fluoride, and pathogens.

• TFC Technology: Built with a Polyamide layer for filtration, supported by Polysulfone and Polyester layers for maximum pressure resistance and durability.

• Versatile Capacities: Available in various GPD (Gallons Per Day) ratings to suit residential or light commercial needs.

• Universal Compatibility: Fits standard RO membrane housings used in 5-stage and 7-stage systems.

• Trusted Quality: We supply high-performance membranes from industry-leading brands including Sinoflow, Vontron, and Linki.

Selection Guide: Finding Your GPD Capacity

The GPD rating indicates how many gallons of purified water the membrane can produce in a 24-hour period under optimal conditions (25°C and 3.5Bar pressure).

How It Works

• The Molecular Sieve: High-pressure water is forced against the semi-permeable TFC membrane. Only pure water molecules are small enough to pass through the Polyamide layer.

• The Rejection Stream: Dissolved impurities are washed away to the drain (wastewater), preventing them from ever reaching your glass.

• The Result: Ultra-pure water suitable for drinking, laboratory use, aquariums, and sensitive medical processes.

Maintenance & Service Life

To protect your membrane and ensure it lasts 1 to 3 years, you must replace your sediment and carbon pre-filters every 6–12 months. Signs it is time to replace your RO Membrane:

1. Reduced Flow: The storage tank takes significantly longer to fill than usual.

2. Increased TDS: Your water starts showing higher Total Dissolved Solids readings on a TDS meter.

3. Taste Change: A return of saltiness or chemical taste in the purified water.

Important Note for 400 GPD Users

Before purchasing a 400 GPD membrane, please check your current membrane size code. Size 3012 (approx. 12 inches) and 3013 (approx. 13 inches) are NOT interchangeable.
