A fluid filtration system includes a fluid storage vessel such as a bioreactor, a filter housing including a filter element disposed therein, a pump coupled between the fluid storage vessel and the filter housing, and a flow diverter disposed between the pump and the filter housing. The pump is configured to move fluid from the fluid storage vessel through the filter element, and the flow diverter is configured for selectively directing fluid received from the pump to the first or second end of the filter housing. In a first mode of operation, the flow diverter directs flow through the filter housing in a first direction, while in a second mode of operation, the flow diverter directs flow through the filter housing in a second direction opposite the first direction.

A fluid filtration assembly includes a filter housing having first and second ends and a connector for fluid communication with a fluid storage vessel. A filter element is disposable within the filter housing, and first and second pumps are coupled at the first and second ends of the filter housing. A controller may coordinate the operation of the first and second pumps to induce alternating tangential flow of fluid between the filter housing and the first and second pumps. At least one of the first and second pumps is a diaphragm pump or a plunger pump. The fluid storage vessel can be a bioreactor.

The invention relates to portable liquid supply device, mainly for water from central and other sources or for suspensions, for example pharmaceutical products and nutrient liquids. The invention can be used in household, outdoors, in the garden plots, in health care institutions, for example, for patients with dysphagia, as the source of purified drinking water or nutrient liquids, which go to a patient easily.

Liquid supply device, comprising raw liquid vessel, pressure generating means, liquid treating unit, comprising a lid, liquid supply means, liquid treating element and raw liquid inlet element, characterized in that is configured to supply treated liquid in portions from 1 to 600 ml, preferably from 5 to 100 ml, with velocity from 0.1 to 200 ml/seconds, preferable from 0.5 to 10 ml/sec.

A housing of a liquid separation device that includes an inlet for the gas-liquid mixture and a set of integrated components, the set of integrated components includes a liquid separator vessel to separate liquid from the gas-liquid mixture, and the liquid separator vessel includes an entry port for the gas-liquid mixture, a liquid outlet port, and a gas outlet port. The set of integrated components includes a set of channels, where a wall of each channel is part of the housing, where the set of channels includes an inlet channel to guide the gas-liquid mixture from the inlet to the entry port and an outlet channel to guide gas from the gas outlet port away from the liquid separator vessel. The housing includes at least two opposite housing pieces which can be hermetically sealed together along a sealing line which is situated in a sealing face.

A pump system includes a submersible pump and a filter. The pump has a housing, an intake, and a discharge. The filter includes a filter housing that releasably engages the pump and that overlies the intake of the pump. The filter housing has an intake, an outlet located between the intake of the filter housing and the intake of the pump. A filter chamber is located upstream of the outlet of the filter housing and is configured to receive filter media. The outlet of the filter housing is disposed inline with the intake of the pump. The coupling may comprise a latch that clips or snaps onto part of the pump, releasably attaching the filter housing to the pump. The latch may engage with opposite sides of the pump when releasably attaching the filter housing to the pump. The latch may include a plurality of spaced apart snaps that snap onto the pump.

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 water purification device includes a housing having an outlet for dispensing purified water; a filtration system for purifying water, and a pump mounted to the housing and fluidly coupled between the filtration system and the outlet; and a bladderless accumulator coupled to the pump for accumulating the water. The pump is mounted to the housing via a pump mount that is suspended above the housing. The combination of a bladderless accumulator and pump mount ensures that pulsations generated by the pump are greatly reduced.
