A filtration device includes a first channel member, a second channel member, and a filter. The first channel member has a recess recessed inward from an outer wall surface. A groove is formed is the recess and has an opening in a recessed surface of the recess. First and second channels, each defined by a through-hole, are formed in the first channel member and are connected to the groove. A first connection part connects the groove with the first channel. The second channel member has a projection that detachably mates with the recess. The second channel member includes a discharge channel that has an opening in a projecting surface of the projection, the opening being located over the groove. The filter is disposed along the groove, and positioned at the opening of the discharge channel. When the first and second channel members are placed in a operative relationship, a third channel is formed by the projecting surface of the projection and the opening of the groove. The third channel is connected to the first channel via the first connection part. The third channel at which the filter is positioned has a smaller cross-sectional area than the first channel.

A device for providing purified water from a silt-laden source water having an upper canister, a lower canister, and a filter mounted in the upper canister; wherein the upper canister and the lower canister are fluidly connected via the filter; wherein pre-filtered water is collected in the upper canister and purified water is collected in the lower canister; wherein a pre-filter is fluidly connected between the source water and the upper canister; wherein the pre-filter has a pre-filter canister having an inlet for source water and an outlet for pre-filtered water; wherein the pre-filter canister contains a fine depth filter and a felt filter.

The objective of this invention is to provide a filter module for coating equipment that can improve the efficiency in removing coating-material mist and preventing the outflow of such coating-material mist to the outside. The filter module of this invention is made of a flammable material and includes an outer box, an eliminator and a baffle plate. Of the outer box, the air A2 containing the coating-material mist flows into the outer box from the outer-box inlet and is discharged from the outer-box outlet. The eliminator is formed by arranging zigzag-shaped eliminator elements in parallel to separate the coating-material mist from the air A2. The baffle plate is formed by arranging baffle-plate elements having an inclined surface for guiding the air A2 in parallel into the inflow-side space S2 of the eliminator, and guides the air A2 that has been introduced from the outer-box inlet to the inflow-side space S2.

A device for the formation of turbulence in a liquid, which comprises at least one support (5) of plastic material provided with through holes (6) and at least one woven fabric (7) of synthetic monofilament formed as a single body by co-molding on one face of said support (5). Compared to conventional devices, the device according to the invention offers the advantage of allowing the volume of foam formed on the liquid downstream of the support to be modulated.

Embodiments of the invention provide a filter for use in filtering a fluid slurry that includes particles of varying size, such as pool water including debris. The filter is in electrical communication with a sensor and includes a housing having an inlet to receive the fluid slurry, an outlet, and an internal chamber. An actuator can be coupled to the filter media to move at least a portion of the filter media to vary a dimension of the pores. The filter also includes a controller connected to the actuator that is capable of receiving a signal from the sensor and controls the actuator to change the dimension of the pores based on the signal.

A screen panel assembly includes a screen panel and a raised screen component disposed thereon. The raised screen component includes an inclined screen surface that defines a first plane oriented at a first angle relative to the screen panel and a wedge surface positioned at a back side of the raised screen component. The inclined screen surface has a front edge that is aligned with a top surface of the screen panel and is substantially perpendicular to a longitudinal axis of the screen panel, the first plane being substantially perpendicular to a displacement vector along which the screen panel assembly is accelerated by a vibratory separation device. The wedge surface is adapted to disrupt a flow path of a flow of a material mixture flowing in a longitudinal direction across the screen panel by redirecting the flow around opposing sides of the raised screen component.

A platform has a filter system with a first set of filter modules and a second set of filter modules that is different from the first set of filter modules. Each set of filter modules includes an inflow channel and an outflow channel. A fluid inlet is connected to the first set of filter modules, a fluid outlet is connected to the second set of filter modules, and a separation interface separates the first and second sets of filter modules. The separation interface has a first interface channel to connect to the module outflow channel of the first set of filter modules, and a second interface channel to connect to the module inflow channel of the second set of filter modules. The filter system receives fluid through the fluid inlet and, after the fluid has passed through each set of filter modules, discharges the fluid through the fluid outlet.
