OLTREMARE RO Reverse osmosis membranes

1. Low Pressure Elements
   Oltremare LOW RO membranes have become a global choice in water treatment due to their stable performance at reduced operating pressure. Models LOW1, LOW2, LOW3, LOW4, and LOW7 provide high salt rejection efficiency and contribute to reduced energy consumption. Optimal for domestic and light industrial use, these elements combine economy and reliability.
2. Compact Elements
   Compact Oltremare membranes are designed as a universal solution that combines the housing and filter element in one module. This design allows for reduced installation costs, eliminates the need for an external vessel, and simplifies maintenance. Elements are easily installed, replaced, and provide performance on par with standard LOW and NANO membranes, but with lower overall system costs.
3. XL Elements
   Oltremare XL series membranes are an expanded line of 4-inch low-energy elements in 4040, 4021, and 4014 formats. Thanks to increased active surface area, the modules provide higher performance while maintaining standard dimensions compatible with typical 4-inch housings. This combination makes them an efficient choice for upgrading existing systems without the need for structural changes.
4. Brackish Water Elements
   Oltremare membranes for brackish water (BR) are designed for stable operation under medium mineralization conditions. High performance and efficient salt removal make them suitable for use in industrial water supply, wastewater treatment, agriculture, irrigation, and other areas. Due to their resistance to chemicals and operational reliability, these elements are often used in water preparation systems for boilers, power plants, and oil refineries.
5. Low Fouling Membranes
   Oltremare FOUL membranes are designed to work with contaminated or challenging types of feed water, including municipal effluents and industrial wastewater. The use of special design allows for reduced membrane fouling rate, increased intervals between cleanings, and extended system service life. The smooth surface of the elements also facilitates easier cleaning and increases operational reliability even under unstable conditions.
6. Seawater Membranes
   Oltremare SEA modules are designed for desalination systems with high salt content. They demonstrate stable efficiency under various operating conditions — from local installations on board ships to water treatment systems in hotels and coastal settlements. The variety of sizes allows adaptation to the specifics of each facility and ensures the required permeate quality even under high loads.

The Oltremare RO membrane series is used in various industries — from food processing and power generation to water treatment in hotels, medical facilities, and the agricultural sector. Thanks to high selectivity and stable permeate quality indicators, the modules are suitable for operation in challenging conditions and help maintain system efficiency.
Typical advantages of using Oltremare RO:

• Reduction of total dissolved solids (TDS) in permeate.
• Reduction of total suspended solids (TSS).
• Improved water quality without additional chemicals.
• Optimization of reverse osmosis system operation through reduced energy consumption.
