摘要:
A method and system for treating a fluid includes an electrode with an outer housing having openings in a side wall thereof, a granular conductive material encapsulated within the outer housing, and an electrical terminal located at least partially within the outer housing and in electrical communication with the granular conductive material, wherein the openings are configured to permit ions in a fluid to be treated to pass there through so as to come into contact with the granular conductive material. The system includes a treatment tank and electrodes within the tank being charged to differing polarities by a voltage source. The method includes applying a first polarity to at least one electrode, oppositely charging one or more of other spaced apart electrodes, and flowing the fluid within the space so as to treat the fluid.

摘要:
An electrode for use in a deionization apparatus includes a conductive material that is in a granular form and is arranged in a layer that is defined by a first face and a second face. The electrode includes a substrate that is disposed against the first face, and a first member that is disposed against the second face and is formed to permit a fluid to pass through the first member and into contact with the granular conductive material to permit absorption of ions by the granular conductive material.
摘要:
A process of dewatering an aqueous suspension comprising dosing the suspension with a flocculating amount of a first flocculant to form a thickened suspension and mixing into the thickened suspension a dewatering amount of a second flocculant and subjecting the thickened suspension to mechanical dewatering to form a cake, characterised in that the second flocculant comprises a water-soluble or water swellable polymer that is mixed into the suspension in the form of (i) substantially dry polymer particles or (ii) an aqueous composition comprising dissolved or hydrated polymer having a polymer concentration of at least 2% by weight and having a intrinsic viscosity of at least 3 dl/g.
摘要:
Iso- and heterocyclic phenylsulphonamides can be prepared by reaction of corresponding iso- and heterocyclic amines with phenylsulphonic acid derivatives. The iso- and heterocyclic phenylsulphonamides have thrombocyte aggregation-inhibiting and thromboxane A.sub.2 antagonist action and can be used in medicaments.
