Aqua Hygiene Water is a well-known supplier of Industrial and Commercial Reverse Osmosis membranes in the United Arab Emirates. Our selection includes products from DuPont Filmtec, Hydranautics, LG, Suez (Lanxess), Vontron, Toray, and more. We offer 1.8", 2.5", 4", and 8" diameter RO membranes for residential and industrial applications designed for both seawater and brackish water filtration systems. With Aqua Hygiene, you will find the right reverse osmosis replacement membrane to ensure the top performance of your filtration system.

Brackish Water Membranes

Brackish Water (BW) Membranes are designed to provide high flow rates and optimized salt rejection when treating water at high salinity levels (up to 8,000 ppm NaCl Salinity). To achieve this, BW RO membranes must be used in combination with medium to high applied inlet water pressure (around 200 to 300 PSI). With these requirements met, BW membranes are capable of delivering an excellent balance of both flow and salt rejection.

Seawater Reverse Osmosis Membranes

Seawater Reverse Osmosis (SWRO) membranes are designed to offer long-term cost efficiency for seawater desalination systems. Our high-quality SWRO membranes feature exceptional productivity and salt rejection rate, making them ideal for several applications such as marine and maritime watermakers, sea and land-based desalinators, and seawater and high brackish water desalination plants.

Dupont Filmtec BW30-400 Commercial Reverse Osmosis Membrane

DOW FILMTEC BW30-400 Membrane elements are the product of choice when high-quality permeates are required. BW30-400 is a DOW FILMTEC™ Brackish Water Reverse Osmosis (BWRO) 8” Element, which can separate salts from water. Previously known as BW30 8040, the BW30 400 is produced with an automated fabrication process that ensures precision, consistency, and reliability.


  • Decades of proven performance
  • Delivers high-quality permeate water while minimizing CAPEX
  • Offers the most effective cleaning performance, robustness, and durability due to its widest cleaning pH range (1 – 13) tolerance and the support of Dow technical representative's high rejection gives good water quality;
  • Filmtec performance and quality


The element with the best combination of productivity and salt rejection available. When high-performance counts, CPA membranes from Hydranautics set the standard for RO membrane elements. CPA membranes provide the highest salt rejection rates available - every element on every order for every customer.

Hydranautics' 8040 CPA3 RO Membrane is a composite polyamide membrane element designed to offer high rejection of various contaminants that may be present in water. It can act as pretreatment to reverse osmosis (RO) membranes or as the primary treatment and is available in both 4” and 8” configurations, it offers great flexibility and convenience for many applications. Highly efficient with optimized membrane area and several modern cleaning regimes, the Hydranautics 8040 CPA3 RO Membrane is capable of producing over 600 million gallons per day of pure water and has become the go-to choice amongst global municipalities and industries.
