Description

The 1812 75 GPD Reverse Osmosis Membrane is a high-performance thin-film composite (TFC) membrane designed for domestic and light commercial Reverse Osmosis (RO) systems. Engineered for low-pressure operation, it delivers high permeate flow and excellent salt rejection, making it ideal for producing clean, safe drinking water from municipal, borehole, and low-salinity water sources.

Designed to effectively remove dissolved salts, Total Organic Carbon (TOC), silica (SiO₂), and other dissolved contaminants, this membrane is suitable for residential drinking water systems, beverage production, laboratory applications, and light commercial water purification. Its efficient design provides reliable performance while reducing operating costs through low-pressure operation.

Features:

• Low-pressure operation for improved energy efficiency.
• Produces up to 75 GPD (approximately 284 litres per day).
• High permeate flow with excellent desalination performance.
• Effectively removes dissolved salts, TOC, and silica (SiO₂).
• High rejection of dissolved minerals and contaminants.
• Compatible with standard 1812 membrane housings.
• Suitable for residential and light commercial RO systems.
• Long service life with proper pretreatment and maintenance.
• Reliable and consistent water quality.
• Easy installation and replacement.
