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 where the intake module is above the vortex module, which is above the disk-pack module and the motor module. In a further embodiment, a housing is provided over at least the intake module and the vortex module and sits above the disk-pack module. 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.

A cleaning apparatus, including: a suction system; a separation system; a filtration system; and a garbage collection system at least comprising a first garbage collection cavity configured to collect garbage passing through a primary separation system and a second garbage collection cavity configured to collect garbage passing through a secondary separation system, wherein the first garbage collection cavity and the second garbage collection cavity have a common airtight cover, a bottom of the second garbage collection cavity and a bottom of the first garbage collection cavity are located on the airtight cover in a direction extending outward from a center of the airtight cover, and the first garbage collection cavity and the second garbage collection cavity are isolated in a sealed manner in a direction perpendicular to a surface of the airtight cover.

A compact disc stack cyclone separator includes: a fluid inlet; a vortex generator which generates a forced vortex; a conical or cylindrical vortex generating chamber; a separation chamber which is a cavity formed by downstream open ends of stacked truncated cones; narrow gaps between the stacked truncated cones, a collecting channel for heavy phrase fluid from the gaps between the stacked truncated cones which installed about the outlets of the gaps at upstream open end of the stacked truncated cones to channel heavy phrase fluid to a storage chamber of heavy phrase fluid; and an outlet for heavy phrase fluid to flow out from the storage chamber of heavy phrase fluid, while the outlet of light phrase fluid is annexed to the downstream open end of the last stacked truncated cone which is the downstream open end of separation chamber.

A surface cleaning apparatus comprises an air treatment chamber with a moveable member positioned therein. An end wall of the air treatment chamber is openable in response to a moveable member being longitudinally translated through at least the portion of the air treatment chamber. The driving assembly includes a handle and a drive rod that is rotatably mounted about a longitudinally extending axis of the drive rod between a stored position in which the moveable member is in a stored position and an operable position in which the moveable member is translatable through at least a portion of the chamber. In the stored position, the handle is longitudinally spaced from the first and second ends of the air treatment chamber and, when the driving assembly is in the operable position, the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber.

A surface cleaning apparatus comprises an air treatment member having an air treatment chamber. A moveable member is positioned in the air treatment chamber. A driving assembly is drivingly connected to the moveable member wherein the driving assembly is operable between a stored position is which the surface cleaning apparatus is operable to clean a surface and a cleaned position in which the moveable member has been translated through at least a portion of the chamber, wherein, in the stored position, a portion of the driving assembly is longitudinally spaced from the first and second axially spaced apart ends of the air treatment chamber.

A surface cleaning apparatus comprises an air treatment chamber having a first end, an axially opposed second end, an axis extending between the first and second axially opposed ends and an axially extending air treatment chamber sidewall. The air treatment chamber air outlet is provided at the second opposed end and the first opposed end is moveably mounted between a closed position and an open position in which the air treatment chamber is open. The air treatment chamber has a stationary portion and an openable portion and the openable portion is moveably mounted between a closed position and an open position in which the air treatment chamber is open. When the openable portion is in the closed position, the openable portion and the stationery portion abut along peripheral edges that extend along a length of the air treatment chamber sidewall.

A uniflow cyclone for a hand vacuum cleaner has a dirt chamber that is external to the cyclone chamber and vortex finder, which has a solid portion that is spaced from and faces a dirt outlet of the cyclone chamber and a porous section that is angularly spaced around the cyclone axis of rotation of the cyclone from the solid portion.

A surface cleaning apparatus comprises an air treatment chamber having a first end comprising a first end wall, an axially spaced apart second end comprising a second end wall, a sidewall extending between the first and second end walls, an air treatment chamber air inlet and an air treatment chamber air outlet provided at the second end. A dirt collection region, which is contiguous with the air treatment chamber, is positioned axially from the first and second end walls and is closer to the second end wall than the first end wall.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

A surface cleaning apparatus comprises an air treatment chamber with a moveable member positioned therein. An end wall of the air treatment chamber is openable in response to a moveable member being longitudinally translated through at least the portion of the air treatment chamber. The driving assembly includes a handle and a drive rod that is rotatably mounted about a longitudinally extending axis of the drive rod between a stored position in which the moveable member is in a stored position and an operable position in which the moveable member is translatable through at least a portion of the chamber. In the stored position, the handle is longitudinally spaced from the first and second ends of the air treatment chamber and, when the driving assembly is in the operable position, the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber.
