An apparatus for dewatering sludge comprises a tank having an internal space divided by a dividing wall into an intake chamber and an extract chamber, an intake pipe connected to the intake chamber by an intake valve, a discharge pipe connected to the extract chamber by a discharge valve, and a transfer pipe providing fluid communication between the intake chamber and the extract chamber. The transfer pipe has first opening near the bottom of the intake chamber, and a second opening near the top of the extract chamber. A pump selectively creates positive and negative pressure within the intake chamber. A screen is positioned within the extract chamber between the second opening of the transfer pipe and the discharge pipe.

A suction tube filter arrangement includes a suction tube defining a suction tube direction and a filter member extending along the suction tube direction. The suction tube is at least partially arranged inside the filter member.

A base filter for a diesel exhaust fluid (DEF) filter of a header assembly in a fluid reservoir is disclosed may include first and second semi-cylindrical holder portions having a semi-cylindrical walls concluding at abutment surfaces that face and engage when the base filter is assembled. The semi-cylindrical holder portions have one or more mounting tabs extending inward from inner surfaces of the semi-cylindrical walls. The header assembly may include a header with a cylindrical header boss having mounting recess defined therein. The mounting tabs may be circumferentially spaced about the semi-cylindrical walls to align with and be inserted into the mounting recesses of the header boss the base filter is assembled on the cylindrical header boss. Fasteners may be inserted through fastener bosses of the semi-cylindrical holder portions and into fastener bores of the header boss to hold the semi-cylindrical holder portions together and on the header.

A cleaning assembly for reusable filters comprises a housing and a pressurizing spraying assembly that receives a filter element to be cleaned. The pressurizing spraying assembly can be secured in position relative to the housing using a mount. The mount can pivot about a pivot axis between a storage position and a use position. The pivot axis can be aligned with a handle axis about which a handle is attached to the housing. The housing can collect runoff from a cleaning operation.

A manifold for a medical waste collection apparatus includes a fluid path connection portion and a storage connection portion. The storage connection portion includes a mounting connector in communication with the fluid path connection portion and coupled with the mounting base of the waste collection apparatus, and a docking valve arranged inside a connector cavity defined by inner walls of the connector. The docking valve is in an open state when the mounting connector is coupled with the mounting base, and a passage is formed between the storage connection portion and a waste collection container in the waste collection apparatus. The docking valve is in a closed state to close the connector cavity when the mounting connector is decoupled. The connection port between the manifold and the apparatus does not require manual opening or closing, thereby preventing waste from contaminating the environment, equipment and personnel, and enhancing convenience of use.
