Separation and dewatering of biological microparticles from low concentrated suspensions by using the energy efficient thin film filtration

Z. Lam*, H. Nirschl, H. Anlauf, Karlsruhe Institute of Technology (KIT), Germany

The cake filtration is considered to be a low cost process for the continuous separation of inorganic and organic particles and also provides a very gently product treatment. The continuous sedimentation in the centrifugal field or the precoat filtration on a vacuum drum filter is currently used for the separation of biological microparticles. Separation in a centrifugal field with a low density difference between the particles and the continuous phase requires a high centrifugal force to achieve the desired separation efficiency. Therefore a large amount of energy is required to accelerate the suspension. An alternative separation method for biological microparticles would be the cake filtration, but this method however causes a high filter cake resistance.

The aim of this project is to develop a continuous thin film filtration method for the cake filtration...
