A skid (700) for use in separating biocomponents includes a housing (701) bounding a compartment (708), the compartment being partially bounding by a mounting platform (709); and a loading assembly (800) secured to the housing so as to communicate with the compartment. The loading assembly (800) includes an alignment plate (808) having a top surface with cavity (814) recessed therein, the cavity communicating with the compartment; a drive rotor (15) rotatably disposed below the alignment plate and at least partially encircling the cavity, the drive rotor including one or more magnets; a motor (169) coupled to the drive rotor for selectively rotating the drive rotor about the cavity; and a mount at least partially encircling the drive rotor and communicating with the compartment, the mount including a mounting plate having one or more mounting elements upstanding therefrom, the mount being movable between a raised position wherein the mounting plate is aligned with the alignment plate and a second lowered position wherein the mounting plate is disposed at an elevation lower than the alignment plate.

Disclosed is a centrifugal piston including a piston body and a weight. In a centrifugal environment, a first outer weight surface of the weight is configured to get in contact with a first inner body surface of the piston body, and a gap is formed between the first inner body surface and a recess of the weight.

The invention in at least one embodiment includes a system for treating water having an intake module, a vortex module, a disk-pack module, and a motor module. In at least one embodiment, a water system includes vortex housing having an interior wall defining a vortex chamber in fluid communication with the expansion chamber of said disk-pack turbine and inlets into the vortex chamber, and the vortex chamber having an upper section with a bowl or modified concave hyperbolic shape into which fluid is received from said inlets and a lower section with a conical or funnel shape with a steep vertical angle of change that opens into expansion chamber. In at least one further embodiment, the disk-pack module includes a disk-pack turbine having a plurality of disks having at least one waveform present on at least one of the disks.
