The present invention is intended to provide a cell treatment apparatus and a method for treating cells that can suppress a variation of a treatment time of treating cells using laser light. The cell treatment apparatus of the present invention includes: a cell treatment chamber in which cells in a cell culture vessel are treated; an observation unit that can observe the cells; a laser projection unit that can project a laser image onto the cells; a laser moving unit that can move the laser projection unit; and a control unit. The laser projection unit includes: a laser light source; and a laser image generation portion that generates the laser image to be projected onto the cells from laser light oscillated from the laser light source. The control unit controls generation of the laser image by the laser image generation portion. By moving the laser moving unit from a projection start position of the laser image at one end of the cell culture vessel to a projection end position of the laser image at the other end of the cell culture vessel, the laser projection unit projects the laser image from the projection start position of the laser image at one end of the cell culture vessel to the projection end position of the laser image at the other end of the cell culture vessel.

Pulse dosing is used to administer a cleaning formulation into a fluid process stream flowing through structural components of a processing facility. The fluid process stream may contain corn, corn-derived products, or a combination thereof, or the fluid process stream may contain a process condensate, a rinse fluid, a cleaning fluid or any combination thereof. The processing facility may be an ethanol processing plant, a protein processing plant, a corn oil processing plant, an ethanol and corn oil processing plant, an ethanol and protein processing plant, or an ethanol, corn oil and protein processing plant. Pulse dosing may include administering the cleaning formulation into the fluid process stream for a period of x seconds every y minutes, with no administration of the cleaning formulation between the periods of x seconds.

The present invention relates to a particulate material separation assembly. It comprises a filtration membrane and an antifouling device. The antifouling device comprises one or more magnets and a plurality of magnetisable particles. The one or more magnets cause the plurality of magnetisable particles to self-assemble into dynamic bristles, thereby forming a brush. The particulate material separation assembly is particularly useful in the context of micro algae harvesting.
