Patent DE-2606586-A1 (DE)
Inventor: MARQUARDT KURT
IPC: B01D3/00
Filed: 1976-02-19
Abstract: To recover materials of a treatment bath (12) from downstream washing baths (14, 16, 18), the materials are returned (22, 24, 26) to the treatment bath (12) by membrane separation (OI). By an additional membrane separation (OII), sufficient liquid is taken off (42, 40) from the treatment bath (12) such that the concentrate recovered during the membrane separation in the washing baths (14, 16, 18) can be completely returned to the treatment bath (12). For this purpose, the concentrate stream of the additional membrane separation (OII) is returned (44) to the treatment bath (12), while the permeate stream is fed (46, 28, 29) to one (14) of the washing baths (14, 16, 18). As a result, the use of the recovery method is possible, without additional units such as evaporators, for treatment baths from which only small amounts of concentrate are carried out. <IMAGE>
