In a sewer cleaning vehicle is provided having a container for the water required for cleaning the sewer and/or the sludge obtained during cleaning of the sewer, and an extension arm which is liftable and lowerable and/or rotatable about a vertical axis and which is accommodated on the container for the manipulation of a flushing hose which can be supplied with compressed water and which can be inserted into the sewer. A suction hose with a suction draft can be lowered into the sewer. At least one further working device which is provided for working the sewer and which can be manipulated by the extension arm is carried along on the vehicle and can be loosely accommodated on an associated retaining device provided on the vehicle side and can releasably be coupled to the extension arm when required by an associated coupling device.

A combination vehicle (10) for cleaning a sewer includes a water jetting system (12) with a frame (34) mounted to a first end (38) of the vehicle (10) and horizontally spanning substantially the width thereof, and a slide carriage (36) operatively engaged with the frame (34) and slideable therealong. A hose reel frame (28) pivotally connects to the slide carriage (36) and is pivotal about a vertical axis, and supports a hose reel (30) that is rotatable about a horizontal axis and configured to support a hose (32). The hose (32) operatively connects to a water jetting source (46) to supply pressurized water for use in cleaning the sewer. A controller (44) operatively connects to the hose reel frame (28) and is operable to move the slide carriage (36) along the frame (34), and also to pivot the hose reel frame (28) relative to the vertical axis, thereby to enhance safety and maneuverability in locating the hose (32) in a desired position for cleaning a sewer.

A cleaning vehicle generally has a grey water reservoir having a pre-filter; an aspiration conduit leading into the grey water reservoir upstream from the pre-filter and a vacuum pump adapted to create a vacuum inside the grey water reservoir to draw grey water; a vortex separation subsystem connected downstream from the pre-filter; a filtration bag subsystem connected downstream from the vortex separation subsystem; a filtrate reservoir connected downstream from the filtration bag subsystem; a high pressure hose having an end connected downstream from the filtrate reservoir and another end having a high pressure spray nozzle; a filtrate path extending from the grey water reservoir to the high pressure spray nozzle via the pre-filter, the vortex separation subsystem, the filtration bag subsystem and the high pressure hose; and at least one pump adapted to entrain a flow of fluid along the filtrate path.

A boom hose apparatus for a material collection vehicle includes a telescoping boom assembly and a hose assembly supported by the boom assembly. The boom assembly includes a plurality of telescoping conduits. A flexible hose is received through the telescoping conduits and can slidably extend from, or retract into, the conduits independently from the telescoping of the conduits.

A septic hose compressor is provided that is attachable to a conventional septic hose such as the hoses used in RVs. The system includes an air-tight second end cap that attaches to the second end of the septic hose. The first end cap attaches to the first end of the septic hose and includes a one-way valve or other flow restriction mechanism to allow for the removal of air from the interior of the septic hose to provide a compressed septic hose that is suitable for storage.

A method for managing a live stream of waste stream fluids in which a controller of an applicator unit accesses data indicative of a first concentration of at least one contaminant in a volume of waste stream fluids loaded in the applicator unit, and a contaminant capacity profile indicative of an amount of the at least one contaminant to be applied in the land area. At least a portion of the volume of waste stream fluids loaded in the applicator unit is applied on at least a portion of a land area based on the first concentration of the at least one contaminant in the volume of waste stream fluids and the contaminant capacity profile. The controller generates an updated contaminant capacity profile based at least in part on the volume of waste stream fluids applied on the land area and the first concentration of the at least one contaminant in the volume of waste stream fluids applied to the land area.

A machine for processing liquid or semi-liquid food products, includes: a frame including a front wall and a lateral wall; at least one container for containing the product to be processed; a stirrer mounted inside the container; a thermal treatment system, operatively connected to the container to heat the walls thereof; a dispenser connected to the container to allow extracting the product to be processed, the dispenser being mounted on the front wall of the frame. A supporting rod, having a longitudinal axis, is coupled to the lateral wall and movable in rotation about an axis perpendicular to the lateral wall, between a rest position and an operatively active position. A shelf is rotatably coupled to the supporting rod. The supporting rod supports the shelf. The shelf is movable in rotation about the longitudinal axis between an inoperative position and an operative position.

Embodiments of the present invention include a hose handling system having a hose guide plumbed via a wash line to a fluid delivery device. The hose guide includes a pulley installed on a frame member, and a spray nozzle adapted to dispense a wash mixture. The hose guide is adapted to guide a hose as the hose is inserted into or withdrawn from a manhole, with the hose traversing the pulley. The wash mixture can be delivered through a wash line to the hose guide, which sprays the wash mixture on the hose in order to reduce or eliminate gross contamination or microbial contamination on the hose. The wash mixture typically, but not necessarily, has a freezing point below 32 F. and includes: a quaternary ammonium compound, an alcohol or glycol, an alcohol ethoxylate, and a fragrance.

An example system includes an auger assembly that is attachable to a vacuum system, in which the auger assembly includes a hose, an auger, and an auger motor. The hose includes an inlet at a distal end and an outlet at a proximal end. The auger includes a shaftless helical blade having a portion that is radially enveloped by the hose. The vacuum system is adapted to suck material from the septic tank or pit latrine via the hose. The auger motor is adapted to rotate the auger about a helical axis in a first direction, in which the rotation about the helical axis in the first direction causes the shaftless helical blade of the auger to translate along the helical axis from the outlet of the hose towards the inlet of the hose.
