The invention belongs to the technical field of composite membrane, and in particular discloses a UIO-66-NH.sub.2 doped organosilicon high salinity wastewater treatment membrane and a preparation method thereof. The membrane is formed into UIO-66-NH.sub.2/organosilicon hybrid membrane on the prefabricated ceramic support surface through the dip-coating method by doping the UIO-66-NH.sub.2 metal-organic framework material into the organosilicon polymeric sol. The UIO-66-NH.sub.2/organosilicon hybrid membrane prepared by the present invention exhibits high water permeability (up to 1.6×10.sup.−10 m.sup.3/(m.sup.2 s Pa) and high salt retention (NaCl retention rate is more than 99.9. %) in the application of pervaporation desalination, and maintains stable membrane structure in the treatment process of TDS>5 wt % high salinity wastewater.

A spin filter plate is disclosed. The spin filter may be mounted in any type of separator/filter system used in irrigation system. The spin filter plate enables to create a cyclonic flow of the fluid, independent of the angle the fluid is supplied to the filter system.

An apparatus for separating out and removing screenings from wastewater includes a screening device having a screen surface through which the wastewater flows during operation of the screening device and screenings carried along in the wastewater are at least intermittently retained. The apparatus includes a sensor and a controller. The sensor monitors the screenings in the area upstream from the screen surface and/or in the area of the screen surface. The controller outputs a message when the screenings have one or several properties which have been defined and have been recognized by the sensor. In addition, a method for operating the apparatus and a system including the apparatus are provided.

An air cleaner for a fuel cell vehicle includes: a case having an inlet and an outlet; and a filter element fixed to the case, the filter element being configured to section the case into an inlet side and an outlet side and filter air flowing from the inlet side to the outlet side. A locking projection projecting toward the inside of the case is provided on the inlet side in the case. A first prefilter, a second prefilter, and a chemical filter are sandwiched between the locking projection and the filter element in the order of the first prefilter, the chemical filter, and the second prefilter from the upstream side as the inlet side of the filter element inside the case toward the downstream side as the outlet side of the filter element inside the case.

An oil supply apparatus for a vehicle includes: an oil pump that supplies oil in an oil pan that stores the oil circulating in an engine; an oil supply passageway that supplies the oil from the oil pump to a lubricating part and a hydraulic actuating part of the engine; and a bubble separating unit that is provided in the oil supply passageway and separates bubbles contained in the oil.
