Document Type and Number:
WIPO Patent Application WO2006027560
Kind Code:
A3
Abstract:
An activated sludge system for the purification of wastewater includes a membrane reactor comprising: (i) an array of pairs of vertical membranes (14) parallel to each other, (5) the membranes being spaced apart from each other and being permeate to liquid but substantially impermeable to solid particles, (ii) liquid flow channels between the membranes (14) of each pair, (iii) a liquid-collecting channels communicating with the liquid-flow channels for receiving liquid which has permeated through the membranes (14), and (iv) gaseous fluid sparging ducts (5) allocated to and co-planar with the respective pairs of membranes (14) and extending substantially horizontally for introducing gaseous fluid into a mixture of the liquid and the solid particles about the array, so that the gaseous fluid rises through the gaps (8) among the outer major surfaces of the membranes (14), each of the ducts 5 having therealong only one row of sparge holes (6), those holes (6) being downwardty directed for emitting the gaseous fluid downwardty .
