The Reverse Osmosis Membrane Element (33-2521) is built to deliver a strong balance of performance, reliability, and seamless integration. Optimized for seawater desalination, it combines high salt rejection with steady production rates, making it ideal for compact marine, offshore, and mobile water purification systems.
Its thin film composite construction minimizes energy use while maintaining excellent water quality - an advantage for operators focused on efficiency and sustainability. Each element is made from high-grade materials and rigorously tested to ensure long-term performance in harsh environments.
Designed for compatibility with standard pressure vessels, including Parker Village Marine and Sea Recovery systems, the 33-2521 membrane allows for straightforward installation or replacement. Its durable design supports extended operational life and dependable output, reducing maintenance needs and overall operating costs.
The 33-2521 membrane is built to industry specifications, ensuring full compatibility with all standard pressure vessels. Whether you're equipping a Parker Village Marine or Sea Recovery system, or retrofitting another RO brand, this membrane offers a secure fit and hassle-free installation. Its universal design helps simplify maintenance, minimize downtime, and allows operators to replace membranes quickly and confidently.
Each membrane element is subjected to rigorous performance testing to guarantee reliability in real-world desalination environments. Parker's commitment to quality ensures that every membrane consistently meets output expectations. To protect membrane integrity during shipping, storage, or system shutdowns, elements are delivered ready for preservation - with guidance for using standard sodium metabisulfite storage solutions to prevent biological growth and extend shelf life.
These RO membranes are specifically designed for use in Parker Village Marine and Sea Recovery Watermaker systems, while also fitting many other industry-standard pressure vessel housings. Both system lines are known for delivering reliable freshwater production through reverse osmosis and are used across a wide range of applications - from private yachts to commercial and military vessels.
While Village Marine systems are built for durability and dependable operation under demanding conditions, Sea Recovery units focus on user-friendly, automated performance with high efficiency. Parker membranes ensure that both system types maintain strong performance and deliver clean water, even during continuous saltwater operation.
Parker’s Sea Recovery series includes compact to large-scale RO systems designed for marine use — from leisure boats to commercial vessels. With automated operation, low energy use, and minimal maintenance, these systems ensure reliable freshwater production at sea. Built for efficiency and ease of use, Sea Recovery units offer a smart solution backed by a proven quality.
