WO/1985/004819A1
Free excess charge which is net unipolar is introduced, preferably by charge injection, into the continuous phase. The charge transfers, through the continuous phase, to the dispersed phase and an induced electric field is thereby set up...  
WO/1985/004818A1
Particles/droplets/bubbles forming a dispersion in a continuous fluid can be increased in size by conglomeration induced by introducing free excess charge which is net unipolar (for example, by charge injection) into a body of the disper...  
WO/1985/002783A1
An improved method and apparatus for filtration includes an outer stationary body (10), an inner rotating body (12) defining a gap with the outer body for receiving a fluid sample (14), the surface of one of the bodies defining the gap b...  
WO/1985/002781A1
A process of washing a crystal-mother liquor mixture to produce a mass of purified crystals in a purification zone containing two sets of sub-zones, respectively denoted as Type A sub-zones and Type B sub-zones, that are laid sequentiall...  
WO/1984/001568A1
Process for obtaining aluminium trihydroxide, of mean diameter adjusted on demand in the interval from 2 to 100 microns, of unimodal distribution and of low dispersion, comprising the hot decomposition of an supersaturated solution of so...  
WO/1984/001569A1
Process for obtaining aluminium trihydroxide having a mean diameter controlled on demand, lower than 4 microns, of unimodal distribution and low dispersion, comprising the hot decomposition of a sodium aluminate supersaturated solution i...  
WO/1984/000117A1
An apparatus for concentrating a suspension consisting of a hollow cylinder (1) in which one or more tubes (2) of a constant outward diameter extend in axial direction, in the wall of each tube at least one filter (3) being mounted formi...  
WO/1984/000118A1
A method and apparatus for treating in counter current of suspended particles with a liquid, whereby the particles and the liquid are tranferred in opposite directions through a contact zone (1) which, at some places, spaced in axial dir...  
WO/1983/001010A1
An apparatus for and method of preparing a slurry for a purification apparatus such as a wash column. A slurry is produced in a crystallizer. The crystals are essentially removed from the concentrated mixture and transported to a more di...  
WO/1983/001011A1
A liquid purification system which removes impurities from liquids, such as salt from water. The system as depicted, for example, in Fig. 2, includes operationally interconnected vaporization means (22), condensing means (23) and heat ex...  
WO/1982/000417A1
An activator for initiating crystallisation of a supercooled salt solution comprises a thin trigger (14) of sheet metal having two configurations between which it is bendable with snap-displacement. The trigger (14) has multiple pin-hole...  
WO/1982/000459A1
The purification method of polluted water by dissolved materials which are separable through crystallization, consists in circulating the solution in a heat exchanger where the vaporization temperature is reached, in feeding the solution...  
WO/1981/003016A1
The essential feature of the process according to the invention lies in that solid crystalline matters, respectively precipitates are gained from the solution by means of chemical reactions, in such a manner, that at least one of the com...  
WO/1979/001052A1
A method for preventing fouling in apparatus used to separate a solvent from a solute which includes a semi-permeable membrane barrier is disclosed. The method comprises providing a quantity of nucleation crystals in the fluid stream pas...
