The inventors have determined the theoretically expected characteristics of the produced nanobubbles, found new characteristics by analyzing data experimentally collected, and elucidated the relationship among the characters. Specifically, the inventors have found that a nanobubble has features such as decrease of the buoyant force, increase of the surface area, increase of the surface activity, generation of a local high-pressure field, interface activating action, and sterilizing action thanks to electrostatic polarization. By the association among the features, any of wide variety of objects can be cleaned with high performance and with light environmental load thanks to the function of adsorbing foul components, the function of cleaning the surface of an object quickly, and the sterilizing function, and polluted water can be purified.

Concentrated aqueous bromine solutions and their preparation
Described is a process of producing a concentrated liquid biocide formulation. Mixed together are (a) bromine chloride or bromine and (b) an aqueous solution of alkali metal salt of sulfamic acid having a pH of at least about 7, in amounts such that (i) the active bromine content of the solution is at least about 100,000 ppm (wt / wt), and (ii) the atom ratio of nitrogen to active bromine from (a) and (b) is greater than 1 when bromine is used and is greater than 0.93 when bromine chloride is used. Use of bromine chloride as the source of the active bromine in the process is preferred because in the resulting aqueous compositions, all of the bromine of the bromine chloride is made available as active bromine in solution. In other words, the chlorine of the bromine chloride is converted in the process to dissolved alkali metal chloride salt, thereby liberating all of the bromine as the active bromine content of the biocidal composition.

Fully automatic and energy-efficient deionizer
InactiveUS20030098266A1Easy to assembleImprove efficiencyLiquid separation auxillary apparatusSeawater treatmentAutomatic controlComputer module
A fully automatic deionizer comprising five sub-systems for removing ionic contaminants from various liquids at low energy consumption is devised. Based on the charging-discharging principle of capacitors, the deionizer conducts deionization through applying a low DC voltage to its electrodes for adsorbing ions, while more than 30% of the process energy is recovered and stored by discharging the electrodes. At the mean time of discharge, surface of the electrodes is regenerated on site and reset for performing many more cycles of deionization-regeneration till the desirable purification is attained. In one moment, both deionization and regeneration proceed simultaneously on different groups of electrode modules, and in the next moment the electrode modules quickly switch the two processes. Such swift reciprocating actions are engaged in synchronized coordination of sub-systems of electrode modules, energy management, fluid flow, and automatic control.

The present invention relates to carbon-carbon composite material comprising a carbonaceous carrier and nanosize carbon structures (e.g. CNT or CNF), wherein the nanosize carbon structures are grown on the carbonaceous carrier. The carrier may be porous, as in activated carbon or consists of carbon black particles. In accordance with the invention, nanocarbon growth in the pores of porous carriers can be realized. The process for the manufacture of a this carbon-carbon-composite material comprises the steps of treating a carbonaceous carrier material with a metal-containing catalyst material, said metal being capable of forming nanosize carbon structures, and growing nanosize carbon structures by means of a CVD (chemical vapour deposition) method on the treated carrier in a gas atmosphere comprising a carbon-containing gas, followed by an optional surface modification step. This process allows optimising porosity, hydrodynamical properties and surface chemistry independently from each other, which is particularly beneficial in respect of the use of the composite for water purification. Carbon black-based composites are particularly useful for filler applications.
