Designed for light commercial and community settings, our Household Large Flow Water Purification RO membrane is a high capacity RO membrane engineered to deliver a high volume of purified water. Perfect for small businesses, cafes, and small community water treatment systems, this commercial reverse osmosis element puts out 800 gallons per day or more. It effectively reduces dissolved solids, chemicals, and contaminants, giving you a reliable, continuous supply of clean water. Plus, its low-energy design keeps things efficient, making it a cost-effective solution for point-of-use applications that need higher flow rates.
High-capacity output – This membrane is built for high volume, delivering up to 800 GPD of purified water. That makes it perfect for applications that go beyond what a typical home needs.
Energy-efficient operation – With its low-energy design, it reduces the feed water pressure required, which lowers electricity use and overall operating costs for small businesses.
Consistent water quality – Using advanced reverse osmosis technology, it reliably removes a wide range of contaminants, giving you dependable water quality for drinking and cooking.
Durable and long-lasting – Made with industrial-grade materials, this element is built to handle continuous operation. That means a longer service life and fewer replacements.

Small commercial establishments – Perfect for cafes, restaurants, and offices where a point-of-entry RO system provides clean water for cooking, drinking, and ice makers.
Community water systems – Used in small community water treatment projects, like rural schools, clinics, or small villages, to provide a central source of safe drinking water.
Multi-family residential buildings – Installed in apartment buildings or condos to supply purified water to multiple units from one efficient system.
Make sure your pre-filtration system (sediment and carbon filters) is properly installed and maintained. This protects the RO membrane from clogging and chlorine damage.
Follow the system manufacturer's startup guidelines—especially slow pressurization to avoid damaging the element.
Monitor system performance regularly, including flow rate and TDS readings, to know when the membrane needs cleaning or replacement.
When replacing, lubricate the O-rings with a water-based lubricant and make sure the element is seated correctly in the housing.
Q: Can this membrane handle well water?
A: It can, but well water often requires robust pre-treatment, including a sediment filter and a carbon filter to remove hydrogen sulfide or iron, to prevent premature fouling of the membrane.
Q: How often should it be replaced?
A: Replacement frequency depends on feed water quality and pre-treatment. Typically, with proper pre-filtration, it can last 2-3 years. A significant drop in flow rate or rise in product water TDS indicates the need for replacement.
