A liquid cleaning element has a cleaning medium and a carrier medium connected to each other. The carrier medium is provided with a liquid connector to connect to a line for liquid to be cleaned or cleaned liquid. The liquid cleaning element has a bend in a section provided with the cleaning medium and the carrier medium. The carrier medium, prior to connection to the cleaning medium, is pre-manufactured in a final shape of the liquid cleaning element. The liquid connector has a cylindrical suction socket and is arranged at or integrated in the carrier medium. A liquid cleaning system is provided with the liquid cleaning element and a holder holding the liquid cleaning element. In a method for producing the liquid cleaning element, the carrier medium is pre-manufactured in a final shape of the liquid cleaning element and the cleaning medium is connected to the pre-manufactured carrier medium.

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. —15—
