摘要:
Disclosed is a method and apparatus for manipulating fluids. The apparatus may include a microfluidic structure including inlet channels (1 and 2) and outlet channels (306, 307, 308, 309, 310, 311, 312, 313, and 314) oriented among bifurcated (5), trifurcated (6) and merging junctions (7 and 8). The apparatus splits and merges fluids flowing in the channels to produce successive dilutions of the fluids within the outlet channels. Multiple apparatus may be combined in serial, parallel, combined serial and parallel and/or stacked configurations. One or more apparatus may be used alone or to provide various devices or chambers with the diluted fluids.

The invention provides an injector device for a water treatment apparatus, and a method of use. The injector device comprises a first coupling for fluid connection to a source of liquid to be treated; and a second coupling for fluid connection to at least one liquid treatment vessel arranged to expose liquid in the vessel to ultraviolet radiation in an advanced oxidation process reaction. The device comprises at least one injection port for injecting at least one gas into a liquid flowing through the injector device. The injector device is at least partially formed from a material that is transmissive to ultraviolet radiation. In another aspect, a water treatment apparatus defines a plurality of parallel flow streams between the inlet of the apparatus and the at least one liquid treatment vessel. The injector device comprises an injection port for each of the plurality of parallel flow streams.

摘要:
A cylindrical mixer having an opening portion on both ends forms an axial flow path and a first fluid introduced into the axial flow path through the opening portion at one end flows therethrough in the axial direction and the first fluid exits from the opening portion at the other end; and a spiral flow path and a second fluid introduced into the spiral flow path through a hole formed in a peripheral wall of the mixer is made to flow along an inner peripheral surface of the mixer while being swirled in a spiral manner about an axis of the axial flow path so that the first fluid and the second fluid are mixed and a mixture of the first fluid and the second fluid exits from an opening portion at the end to refine and homogenize a dispersion phase on a micro level to a sub-micro level.

The invention provides a method for producing a peroxymonosulfuric acid solution with high stability, including the steps of mixing 35 mass % or more of hydrogen peroxide and 70 mass % or more of sulfuric acid to react them, cooling the reaction solution to 80° C. or lower within five minutes after initiation of the mixing step, and diluting the reaction solution with water four times or more as much as the reaction solution by mass.
摘要:
A fractal fluid distribution system for use in a vessel is described wherein two phases are distributed separately and then finally mixed in a set of stacked fractal plates which are off set from one another by rotation around a central axis. Each of the two phases is fed from the top of the vessel. The flow paths of each individual phase have approximately the same length. A header is provided to allow feeding the two phases separately without interference with the final distribution outlets.
