Vortical cross-flow filtration system

A filtration system comprising:

• a first filtration region comprising
• a first opening configured to receive a fluid to be filtered, and
• a first filter configured to filter the received fluid into a first filtered fluid and a retentate fluid that retains filtered particles from the received fluid,
• the first filtration region configured to discharge the retentate fluid to a second opening and to discharge the first filtered fluid to a third opening;
• and
• a second filtration region configured to receive the retentate fluid from the second opening, the second filtration region comprising a second filter configured to filter the retentate fluid to produce a second filtered fluid and to retain filtered particles filtered by the first filter and the second filter.

A filtration device comprising:

• a vortical filter comprising a first opening, a second opening, a rib, and a cross-flow filtration region between the first opening and the second opening;
• and
• a collection unit,
• wherein the rib includes a rib height in a range between 2.0 mm and 6.0 mm,
• wherein the vortical filter is configured to generate vortices in a fluid entering the vortical filter via the first opening and being configured such that filtered fluid exits through a filter media of the cross-flow filtration region,
• wherein the vortical filter is configured such that fluid containing filtered particles substantially exit the vortical filter at the second opening,
• wherein the collection unit comprises a collection filtration region configured to receive the fluid containing filtered particles from the second opening and to retain the filtered particles while permitting additional filtered fluid to pass through the collection unit, and
• wherein a percentage of filtered fluid exiting through the filter media of the cross-flow filtration region is in a range between about 60% and 99% after the second fluid filtration cycle.

A filtration device comprising:

• a vortical filter comprising a first opening, a second opening, a rib, and a cross-flow filtration region between the first opening and the second opening;
• wherein the rib includes a rib height in a range between about 1.0 mm and 5.0 mm,
• wherein the rib includes a rib width in a range between about 5.0 mm and 23.0 mm,
• wherein the rib includes a number of revolutions in a range between about 2.0 and 6.0,
• wherein the vortical filter includes a helix angle of about 11.5 degrees,
• wherein the vortical filter includes a helix pitch in a range between about 7.0 mm and 31.0 mm,
• wherein the vortical filter includes a helix inner diameter in a range between about 25.0 mm and 75.0 mm,
• wherein the vortical filter has a raker reduction ratio β/α in a range between about 2.5 and 5.5 including the end points,
• wherein the vortical filter is configured to generate vortices in a fluid entering the vortical filter via the first opening and being configured such that filtered fluid exits through a filter media of the cross-flow filtration region, and
• wherein the vortical filter is configured such that filtered particles substantially exit the vortical filter at the second opening.
