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 filtration system includes a filtration device having filter slats positioned in a linear array and connected via a supporting structure, the filter slats being parallel to one another and being fixed at an angle relative to the linear array; and pores created by the filter slats; a fluid flow chamber to hold the filtration device such that fluid passes through the filtration device, the fluid flow chamber having a filtration channel with an inlet to receive fluid and an expulsion channel in fluid communication with the filtration channel; a filtrate channel in fluid communication with the filtration channel such that fluid passes through the filtration device between the filtration channel and the filtrate channel, the filtrate channel having a filtrate channel outlet; one or more pressure modulating structures in fluid communication with the fluid flow chamber such that the pressure modulating structure modifies pressure in the fluid flow chamber.

Methods, devices and systems for treating liquid utilizing an in-line filter having a filter bag positioned within a cage contained in an exit sub-chamber of a housing, the exit sub-chamber isolated from an inlet sub-chamber by a baffle, and an end cap to alternatively seal the inlet sub-chamber so that in one mode the device may function as a screen having an exposed filter bag when the exit end of the device is connected to a suction side of a pump and in another mode as a closed vessel where the end cap is connected to a discharge of a pump or in a further mode where the exit end is connected to a suction side of a pump. The low profile, lightweight, inline filter device provides for versatility and a much needed filter device for two modes of connection to a suction side of a pump while also able to connect to a discharge side of a pump.

In at least some implementations, a jet pump includes a main body having a first inlet, an inlet passage communicated with the inlet, a second inlet, an intake passage communicated with the second inlet, an outlet, and an outlet passage communicated with the outlet and with the intake passage, a jet carried by the main body and having a jet inlet communicated with the inlet passage so that fluid flowing in the inlet passage flows through the jet inlet, and a jet outlet having a flow area less than the jet inlet and less than the inlet passage. The main body is formed in one piece and the jet is a separate piece of material that is inserted into the inlet passage after the main body has been formed.

An apparatus for transferring a liquid includes a conduit, a strainer housing, and a flow control reversing valve. The conduit has an inlet, an outlet, and a centerline extending from a first end to a second end. The strainer housing houses a strainer basket and has an inlet, an outlet, and a centerline extending from a first end to a second end. The flow control reversing valve has a valve body and a valve member. The valve body has a centerline extending from a front side to a rear side. The valve member is movable between a first position wherein liquid flows from a first port to a second port, and a second position wherein liquid flows from the second port to the first port. Each of the longitudinal centerlines of the conduit, the strainer housing, and the flow control reversing valve is substantially vertically aligned with one another.
