| 20090071896 | MEMBRANE BAGS WITH SEAMLESS MEMBRANE SUBSTANCE, USES THEREOF AND FILTRATION UNITS THEREWITH - A membrane bag comprising a volume for permeate collection, wherein the volume is completely enclosed in seamless membrane substance; a filtration unit comprising at least one above-described seamless membrane bag; the use of at least one above-described seamless membrane bag in a membrane bioreactor; the use of at least one above-described seamless membrane bag in water filtration or waste water purification; and the use of at least one above-described seamless membrane bag for the filtration or separation of a mixture of fluids, vapours and particles. | 03-19-2009 |
| 20090078644 | MEMBRANE BAGS WITH SEAMLESS MEMBRANE SUBSTANCE, USES THEREOF, FILTRATION UNITS THEREWITH AND MANUFACTURING PROCESSES - Disclosed are seamless membrane bags for example, a membrane bag comprising a spacer fabric and a volume for permeate collection, the spacer fabric comprising a first part and a second part that are spaced apart and tied together at a predefined distance by monofilament thread and the first and second parts are at least partially embedded with membrane substance and the volume for permeate collection is interposed between the first and second parts. The membrane substance embeds portions of the monofilament thread and fills the spacer fabric along the border of the membrane bag. The membrane substance completely enclosing the volume is seamless. Also disclosed are processes for producing such bags, a filtration unit comprising such a membrane bag and their uses in the separation of fluids, vapours and particles. | 03-26-2009 |
| 20100010247 | NOVEL METHOD FOR PRODUCING BIODIESEL USING AN IMMOBILISED CATALYST - A method produces a fatty acid alkylester by transesterification of a fat or oil and an alcohol. The reaction is catalysed by a heterogeneous catalyst immobilised in a tubular reactor at a temperature between 260 and 420° C. and at a pressure higher than 5 bar. A mixture of the fat or oil and the alcohol is led in a continuous flow through the tubular reactor. The catalyst is preferably a metal oxide or a metal carbonate including an alkaline earth metal. The reaction takes place at reduced residence times and contact times compared to the prior art. | 01-14-2010 |
