③  A New Separation Technology with Ice Filter

      ( Fusible Filter )

 

  

     This technology uses centrifugal filtration with fusible materials, such as ice crystals, to separate emulsions. It removes stable surfactants (e.g., proteins) from oil droplets in emulsions (e.g., fish livers) and promotes the coalescence of the oil droplets. The collected oils are then recovered by melting the ice filter. (Pat.)

​

Separation principle of this technology:

      The fusible filters are compressed against the rotating basket wall surface by centrifugal force. As a result, the emulsions, after reaching the basket wall surface at high speed from the filter layer surface of the fusible filter, are forced to move along the basket wall surface through compressed narrow gaps between the basket wall surface and the fusible filter, and also between the filter crystals adjacent to the basket wall surface. In addition, the viscosity differences between the oils and the aqueous solutions in the emulsions increase with decreasing temperature, thus improving separation efficiency.

 

     This technology has the potential to both disrupt the membranes of microalgae and separate oil and solution from them.
