Welcome to our Residential Reverse Osmosis Membranes. We assemble several models of residential membranes from the small low-pressure membrane, customized designs, inline membranes, or Encapsulated membranes. Our membranes are made of high-quality flat sheets with the TFC technology. This technology consists of a thin layer of polyamide with a thin layer of polyethersulfone or polysulfone on each side. We use it in domestic or residential water purification applications. These elements are mainly used in small water systems such as various household pure water machines, hospitals, and laboratory pure water devices.
