High-speed sealed filter using the cross flow filtration principle
Rotary Filter is operated based on the cross flow filtration principle. Since the slurry flow is parallel to the filter media surface, while the pressure gradient is perpendicular, the cake layer on the filter media surface is peeled off and kept thin. Thus, the filtration speed is kept high for a long time.
Rotary Filter is a sealed filter apparatus that realizes the cross flow by a mechanism of agitating plates rotating adjacent to the filter media surface. The plates form a faster slurry flow than the conventional cross flow filtration. Thus, highspeed filtration is available even with highly concentrated slurry. It is available to filter slurry containing particles of size from submicron to micron, and also to filter a difficult-to-filtrate slurry.
Rotary Filter is a pressurized sealed filter that enables continuous discharging of condensed slurry or cake and is especially effective when it is applied to continuous dehydration, rinsing, and solvent replacement. In addition, the cake concentration is automatically controlled by detecting torque of the agitators, which is determined by the concentration.
Another type of the series, Ceramic Rotary Filters, is lined up for nanoparticle filtration.
