The range of services of the BoCross Dynamic filter allows micro filtration and ultra filtration of even nanoscale suspensions. The shear gap principle ensures almost ideal physical conditions for the separation process and thus, for the high concentration of suspensions.

Dynamic sieve filtration allows the separation of coarse or fine grain fractions. Highly viscous and concentrated suspensions can be filtered in a closed apparatus with high throughput and sharp separation cut.

BoCross Dynamic and BoCross MicroScreen are dynamic crossflow filters for micro, ultra, dia or sieve filtration. With the BoCross filter series, suspensions with high concentrations or viscosities can be thickened, washed, cleared or classified.

In a BDO production plant (butanediol process) 24 BoCross MicroScreen filter units of 10 m² each are applied for recovery of catalyst by dynamic precoat filtration.

From a high valuable polymer dispersion coarse particles (x > 20 µm) have to be separated completely. The difference in density of the particles compared to the fluid is negligible.

The BoCross Dynamic filter is used for concentrating and washing of a modified and very fine titanium dioxide which has to be further processed.

A pharmaceutical suspension is synthesized so that a considerable amount of salt is formed during neutralization. This microfine suspension must be cleansed (washed out) of salt and further concentrated.

For concentrating a fine-particulate special PCC product a BoCross Dynamic filter with 6 m² filtration area is operated.
