Patent DE-3636993-C1 (DE)
Inventor: GEORG DR MAIERSKI HANS FRIEDRI
IPC: C02F9/00
Filed: 1986-10-30
Granted: 1988-03-31
Abstract: The process entails impurities which are dissolved and/or suspended in the waste water being separated out, by precipitation and/or flocculation (3, 9) and subsequent sedimentation (6, 12), as sludge, and the deposited sludge being, before it is further treated or dumped, dewatered in a sludge dewatering stage. The sludge is conditioned by adding kieselguhr and active charcoal (2, 4, 10), each in the form of a powder, to the waste water during treatment. This considerably increases, by utilisation of a synergistic effect, the ease of dewatering the sludge when conventional sludge dewatering devices are used. <IMAGE>

Granted: 1991-07-11
Abstract: A brush (1) with artificial bristles, which is particularly suited as a toothbrush, has bunches of bristles (3) composed of the individual bristles (4), to which the individual bristles (4) may be fused, glued or welded. The individual bristles (4) are arranged at an angle within their bunch of bristles (3) against one another and opposite the plane formed by the bristle area and/or opposite the brush body (2) holding them, in such a way that when pressure is applied they individually move slightly sideways perpendicularly to the bunch of bristles (3) as a whole and thus give way to this pressure and simultaneously increase the effective surface. This effect may be improved or enhanced by individual bristles (4) of slightly differing lengths within a bunch of bristles (3). <IMAGE>
