Composite Polyamide Reverse Osmosis (RO) membrane

Our innovative thin film composite polyamide membranes, combined with state-of-the-art spiral module assembly techniques, offer unmatched performance in removing dissolved salts, contaminants, and microbiological impurities from brackish water sources. With a focus on high reproducibility and scalability, our membranes cater to a diverse range of applications, from small-scale domestic units to larger industrial systems.

Reverse osmosis (RO) technology is a highly efficient solution for desalinating water, providing safe drinking water from brackish and seawater sources. As the demand for decentralized water treatment solutions grows, the use of desalination kits as point-of-use devices is becoming increasingly popular.

At TRL, we specialize in the development and deployment of advanced membrane technologies. Initially focusing on ultrafiltration (UF) membranes and the technology for rolling these membranes into spiral modules, we have successfully transferred these innovations for practical use. Our current focus is on thin-film composite polyamide membranes and their assembly into spiral configurations. These membranes exhibit exceptional capabilities, capable of reducing salinity levels by up to 90% in brackish water, even at feed concentrations of up to 3000 ppm. Additionally, our technology enables the production of commercial-scale flat sheet membranes.

Key Features:

  • Effective removal of dissolved salts to permissible levels, along with microbiological contamination control, ensuring consistent performance in brackish water treatment.

  • Versatile applicability, ranging from domestic to large-scale industrial settings, thanks to the adaptability of our spiral module preparation process.


  • Effective Salinity Reduction: Our membranes efficiently reduce dissolved salt levels, ensuring water is safe for consumption and industrial use.

  • Contaminant Removal: We excel in eliminating impurities such as iron and microbiological contaminants, guaranteeing clean and potable water.

  • Consistent Performance: Our process ensures high reproducibility, delivering reliable performance over time and under varying conditions.


  • Brackish Water Desalination: Our technology is perfect for desalinating brackish water, ideal for drinking, agriculture, and industrial applications.

  • Water Reuse: Industries such as pharmaceuticals, biotechnology, and food production benefit from our membranes in water reuse applications, promoting sustainability.

  • Radioactive Waste Treatment: We play a crucial role in treating radioactive waste, safeguarding the environment and public health.

  • Desalination of brackish water from various natural sources.

  • Utilization across diverse industries including pharmaceuticals, biotechnology, wastewater treatment, electrocoating, paints, dairy, food, and beverage.

  • Radioactive waste treatment, highlighting our membrane’s effectiveness in addressing complex environmental challenges.
