A method and apparatus for contaminant separation utilizes an interleaved array of oppositely charged electrode plates for fluid treatment. Spacing between the parallel electrode plates is graduated so that the volume of the cavities between the opposing electrodes provides varying levels of treatment of a broad range of contaminants from a variety of fluid columns. A fluid flow path extending substantially orthogonal to the direction of the electrical field established between opposing electrode plates provides a feed stream with exposure to the varying levels of electrical charges between the electrode plates. The method and apparatus provide an effective means of contaminant separation by a device having a small footprint and requiring low amounts of electrical energy.

A method of treating a metal surface of a portion of a substrate processing system to lower a defect concentration near a processed surface of a substrate includes forming a protective coating on the metal surface, wherein the protective coating includes nickel (Ni) and a fluoropolymer. Forming the protective coating on the metal surface can further include forming a nickel layer on the metal surface, impregnating the nickel layer with a fluoropolymer, and removing fluoropolymer from the surface leaving a predominantly nickel surface so the fluoropolymer is predominantly subsurface. A substrate processing system includes a process chamber into which a reactant gas is introduced, a pumping system for removing material from the process chamber, a first component with a protective coating, wherein the protective coating forms a surface of the component which is exposed to an interior of the substrate processing chamber or an interior of the pumping system. The protective coating includes nickel (Ni) and a flouropolymer.

The tank for a turbine engine comprises a partition separating a first compartment from a second compartment of the tank , the partition having a first end and a second end, the second end being closer to the bottom of the tank than the first end, the partition being inclined from the first end to the second end in the first direction and in the direction of the first outlet to the second outlet , the partition comprising at least one first Through-hole near the first end and at least one second through-hole closer to the second end than the first hole.

This invention discloses a method for treating wastewater by using integrated aerobic granular sludge membrane biological reactor. Said reactor comprises a reaction pond, in which are placed baffle plates (vertically placed plates and inclined placed plates). The above mentioned plates separate the reaction pond into a reaction zone and a settling zone. In the settling zone, on the side wall of reaction pond is equipped with an effluent outlet tube. In the lower middle part of reaction zone is equipped with an aerator. Above the aerator are placed membrane elements, which are then connected with effluent outlet tube and sucking pump. The operation procedures are: continuously feeding wastewater, feeding aerobic granular sludge into the biological reactor, controlling the temperature, proceeding the biological reaction. This invention has advantages of: simple treatment process, high treatment efficiency, stable operation, obtaining effluent water with the need requirement, long service life of membrane elements, low investment and energy-saving.

A game system moves a player character in a virtual game space in accordance with an operation by a player. Further, the player character's moving amount per predetermined unit time is detected at each predetermined time interval. A predetermined parameter (gage amount) value is calculated at each predetermined time interval based on the moving amount detected at each predetermined time interval. Also, the game system adds the predetermined parameter value calculated at each predetermined time interval for accumulation. In response to a predetermined operation performed by the player, the game system causes the player character to perform a predetermined motion (e.g., special shot) on a condition such that a value obtained as a result of the addition reaches a predetermined value.
