1. A filtering process comprising:
providing a dispersion comprising a liquid and a plurality of particles contained in the liquid;
moving an object relative to the dispersion;
controlling at least one parameter selected from the group consisting of
a viscosity of the dispersion;
a surface tension;
a moving speed of the object;
a shape of the object; or
a dimension of the object; and
selectively removing from the dispersion a plurality of separated particles attached to a surface of the object, wherein an average particle size of the plurality of separated particles is smaller than an average particle size of the plurality of particles of the dispersion before conducting the filtering process.
