Commercial RO Membrane Replacement

SpiroPure commercial reverse osmosis (RO) membrane elements are used in different types of systems, like restaurants, hotels, and office buildings. Brackish water membranes produce high-quality water for brackish and tap water applications with low pressure, providing high permeate flow. For very low pressure and low energy consumption, we offer extremely low-pressure RO membrane elements for ultra energy savings! Our sea water membranes are perfect for treating seawater and other high-sodium applications, with a high NaCl rejection rate. Our commercial membranes are offered in 2.5" x 21" (2521), 2.5” x 40” (2540), and 4” x 21” (4021) sizes.

High-Quality Commercial RO Membranes

At All Filters, we carry a range of filtration products with different features and capabilities to meet the exact requirements of your business or circumstance. Our friendly and knowledgeable customer service team is available seven days a week to provide individualized advice so you can find the right product. We offer three main types of replacement RO membranes in our commercial lineup, including:

  • Extremely Low Pressure Systems: Our membranes for low pressure reverse osmosis filter systems are ideal if you need water filtration but want to keep energy costs as low as possible, and your system is designed for it. For example, homeowners using well water or small businesses like coffee shops that need purified water can benefit from clean water without investing in more expensive filtration products.
  • Brackish Water Systems: Our commercial RO membranes filter brackish water and are perfect for people dealing with water that is more salty than freshwater but less salty than seawater. Places like shopping malls, hotels, laundromats, and car washes can benefit from brackish water models.
  • Seawater Desalination Models: These products are well-suited to people or businesses who require a system for purifying water that contains high levels of salt. They are fitted with sea water membranes and are ideal for people like coastal homeowners and yacht owners, or remote resorts and agricultural farms. These systems have a high salt rejection and the ability to operate in severe conditions.

FAQs on Commercial RO Membrane

How often should I schedule commercial RO membrane replacement?

Generally your commercial RO membrane element will last for around 2 to 4 years. This number can vary by each unique situation, however, such as by the water quality, how much the filter is used, and your system maintenance practices.
How long your commercial membrane lasts will mostly depend upon water quality, usage, and maintenance practices. Higher contaminant levels in water and usage will shorten a cartridge’s life span. But proper maintenance practices can help extend a membrane’s working time.
All Filters brackish water BW series commercial RO membrane filters are better for water conditions with higher total dissolved solids (TDS). If you are looking to reduce high rates of sodium, the seawater desalination SW series filter is the best option.
These membranes use reverse osmosis technology to reduce high levels of TDS down to 0.0001 micron in size. Commercial membranes are able to handle larger amounts of water for applications like smaller hotels, whole house systems, car washes, and agricultural filtration. Read our handy commercial membrane blog to learn more.
To know how often to change your specific commercial RO filter cartridge, look for signs of membrane failure. Signs that your membrane is no longer performing as well include slower flow rates and higher levels of TDS leaching into the filtered water.
