A filtration device comprising a media basket, a baseplate, and a canister. The media basket is affixed to the baseplate. The canister has a cavity therein and is detachably coupled with the baseplate to enclose the media basket. The media basket contains a porous filtration material that efficiently removes contaminants from liquid. The device is configured to establish a first siphon to convey liquid from outside the device into the canister cavity through a canister pipe when a liquid level outside the filtration device is higher than the top of the weir in the canister pipe and configured to establish a second siphon to convey liquid from canister cavity through the top of a center riser pipe and out an outlet pipe when the first siphon has been established and the liquid level outside the filtration device is higher than the top of the center riser pipe.

The present disclosure provides a portable high throughput liquid filter system.

The present disclosure is directed to fluid filtering systems and methods for use during semiconductor processing. One or more embodiments are directed to fluid filtering systems and methods for filtering ions and particles from a fluid as the fluid is being provided to a semiconductor wafer processing tool, such as to a semiconductor wafer cleaning tool.

The invention is directed to methods of providing backwash processes for a synthetic compressible medium filter system. More specifically, the system may include a backwash pump and air blower, and the processes may include at least three sequences of: air and water wash; air purge; and medium compression. The backwash process may be triggered by one or more of a pressure, time point, and/or turbidity set point. The air and water wash sequence may include breaking and washing the medium. The air purge sequence may include removing substantially all of the air entrapped in the medium by providing a backwash water flow for a period of time; and a medium compression sequence compressing the medium while avoiding exposing the medium to air, including introducing raw water and where the backwash and raw water provide enough energy to compress the medium without introduction of air into the medium.

A method for separating catalyst particles from the FCC slurry oil present in the retentate of a filtered FCC slurry oil run-down stream is disclosed. The method comprises backwashing the run-down stream filter with a low boiling point solvent to extract slurry oil from the catalyst in the retentate. The backwash solution is sent to a digester where the catalyst fines are separated from the hydrocarbon component (solvent and slurry oil). The catalyst fines are collected and dried. The dried catalyst fines can be transported via pneumatic systems, and can be regenerated for further use as FCC catalysts. The solvent vapor from the drying process is collected for potential reuse. The hydrocarbon component is sent from the digester to an evaporator to evaporate the solvent from the slurry oil. The FCC slurry oil and the solvent exiting the evaporator can be independently collected. The solvent from the evaporator can be reused in the process.
