Nanofiltration (NF) is a de novo class of membrane filtrations with unique properties ranging from ultrafiltration to reverse osmosis. Thanks to their high removal performance, NF membranes have gained increasing attention from both academia and industry for various applications, especially in water and wastewater treatment and desalination. However, the NF process still requires further improvement in terms of selectivity, separation efficiency, membrane fabrication, operation requirements, and sustainability.

This Special Issue on “Nanofiltration Membranes: Recent Advances and Environmental Applications” of the Membranes seeks to include but is not limited to recent progress in emerging NF membranes fabrication and modification, polymeric and ceramic NF membrane, hybrid and composite NF membranes, organic solvent NF, positively charged NF membranes, NF module and process design, NF removal mechanisms, fouling mitigation strategies, new environmental applications of NF, and predictive modelling of NF membrane processes. Authors are invited to submit their latest original results as full papers or short communications. Furthermore, state-of-the-art and critical reviews and analysis papers are welcome.



GRE pipe is well suited for environments where the corrosion resistance at competitive prices is required.

The Early Rotor Blades

Early helicopters like the famous Bell 47 came with main rotor blades made of wood. The inherent characteristic of wood being strong and flexible provided the perfect material for early rotor blade designs.

There were problems however as wood can easily be damaged by woodpeckers, dust and stones, and even rain causing the blade to swell leading to severe vibrations from an out of balance rotor system.

As the realization of the versatility of the helicopter become more popular, the design and evolution of the airframe and the rotor blades began to move forward.

Materials Development

5. When the RO system is working or there is pressure in the frp membrane housing, it is strictly prohibited to knock, disassemble or move the membrane housings. The surrounding vibration source environment must be strictly controlled.

6. It is strictly forbiden to apply pressure or gravity to the upper part of the membrane shell, or to its corresponding accessories.

7. In order to ensure the inner surface of the fiberglass membrane housing clean, manufacturer use a neutral cleaning solution to clean. It is strictly forbidden to use concentrated hydrochloric acid, concentrated sulfuric acid, etc. as cleaning fluid.

The above is all the content that the editor introduces to everyone, we need to maintain and clean the FRP membrane housings regularly during use.
