The Spiral wound membrane is formed by winding  a flat sheet membrane , feed spacer, permeate carrier and center permeate tube components into a spiral wound membrane module. This design significantly increases the packing density and separation efficiency of the membrane, while facilitating installation and maintenance. The operating principle is based on pressure-driven, selective separation of impurities, solutes or solvents from a solution by means of membrane materials with different pore sizes (MF, UF, NF, RO)

Product Features

• Compact Structure: The rolled membrane packs a large membrane area into a small space with high stacking density. This allows for high - capacity treatment in a limited space, suiting water treatment and separation processes of all scales.

  
  

• High Separation Efficiency: Based on different membrane materials and pore - size designs, it efficiently separates various substances. It has excellent removal of salts, organic matter, and microorganisms in water, with high desalination and retention rates.

  
  

• Broad Operating Pressure Range: The operating pressure can be selected according to application needs and material properties. Rolled reverse osmosis membranes typically operate at 1 - 10 MPa or higher, while rolled ultrafiltration and microfiltration membranes operate at 0.1 - 0.6 MPa.

  
  

• Strong Adaptability: By choosing different membrane materials and adjusting structure and performance parameters, rolled membranes can adapt to diverse materials and conditions, including different water qualities, temperatures, and pH levels.

  
  

• Low Operating Cost：Compared to traditional separation methods like distillation and extraction, membrane separation usually doesn't require heating or phase - change processes. It has low energy consumption and simple operation, resulting in relatively low maintenance costs.

  
  

• Customization Support：For the wide - ranging applications of rolled membranes, UNISOL provides a full spectrum of membrane types (MF, UF, NF, RO). Membrane modules are available as standard products, and can also be fully customized for customers.

Industry Applications

• Food & Beverage Industry: Applied in fruit juice clarification and concentration, milk degreasing and concentration, beer clarification, and enzyme purification.

  
  

• Pharmaceutical Industry: Used for separating and purifying drug intermediates, protein separation in biopharmaceuticals, antibiotic concentration, and removing pyrogens from drug solutions.

  
  

• Industrial Wastewater Treatment: Treats electroplating, printing and dyeing, and chemical wastewaters to recover heavy metal ions, remove organic matter, and enable water reuse.

  
  

• Seawater & Brackish Water Desalination: Removes salt and impurities from seawater to supply fresh water for coastal areas and islands.

  
  

• Chemical Production: In petrochemical and fine - chemical fields, it separates, concentrates, and purifies materials, like separating organic solutions and recovering catalysts.
