CRM for Nanoparticle Purification

Product Information
At chemical engineering etc. field usually face solid-liquid separation process of powder suspend liquid. Along with the technological advance, the dimension of particle is gradually tended in super-pure particle, solid-liquid separation of superfine particle, especially non-homogeneous phase solid-liquid separation makes extremely difficult. Because of particle’s Brownian motion, traditional gravity’s sedimentation almost can’t use.

Considering each kind of filtration technique with filtering cloth as percolation, on the one hand retention performance to super-fine particle filtration becomes bad, product makes a lot loss because of the limitation of percolation, on the other hand it is depend on bridging function of filtration cake layer particle to carry out particle retention, if the grain is more small, filtration cake layer of formation becomes more and more compact, the filtration resistance is also more big, filter speed is more and more small, the rinse which filters is also very difficult, rinsing result is too bad, operate labor strength is heavy.
