Patent DE-3914592-A1 (DE)
Title: Process, apparatus and filter module for cross-flow filtration of liquids
Inventor: SCHMIDT HANS-WEDDO
IPC: B01D65/04
Filed: 1989-05-03
Abstract: In a process and an apparatus for preventing or breaking down a layer covering the filter in the cross-flow filtration of liquids (F1, F1') containing finely divided constituents, in which the liquid (F1, F1') to be treated is conducted through a narrow overflow gap (SP) between a filter surface (PM) and a gap limiter (FM), the gap limiter (FM), by relative motion with respect to the filter surface (PM), is periodically adhesively brought into surface contact with the layer covering the filter which is building up and the layer covering the filter is cleaned off from the filter surface by reactivating the overflow gap (FP) and flow over the filter surface and gap limiter surface. The movable wall is formed by a plastic film membrane (FM) clamped liquid-tightly at the edge into an enclosing housing (1 to 7). The film membrane (FM) can be impinged by a gas source (P/V) or liquid source on the side facing away from the overflow gap (SP) and the filter surface is formed by a flexible permeable membrane (PM). Semi-continuous operation is possible owing to the assignment of a control device (9...22) for the matching guidance of the liquid streams and gap constriction and gap enlargement. By means of a recirculation circuit containing a storage vessel, in particular fermenter (20), sample removal from the current fermenter filtrate (F2) is also possible (Fig. 1). <IMAGE>

Title: Contaminated soil cleaning - by atomic hydrogen passing through suspension in electrolytic cell
IPC: A62D101/43
Filed: 1989-09-16
Abstract: Contaminated masses of soil, specially with a content of arsenic, antimony or mercury, are cleaned within a short time by passing atomic hydrogen through the soil. Prior to the treatment, the soil is converted to a slimy paste by adding water at a ratio of 1:2 to 1:10, followed by treatment in an electrolytic cell with a copper cathode and a nickel anode. A rectangular vat (8) has at both ends gastight lock chambers and in its gastight cover (5) two lateral and one central (7) gas exhaust opening(s). The bottom (8) is lined with a copper cathode (1) and an anode (2), preferably made of RANEY nickel, is provided in the cover. A gastight diaphragm (3) but permeable to ions, is closed by a gastight guide (4). The 1:2 to 1:10 suspension separates into slime (9) and water (10). A voltage of 2V produces atomic hydrogen on the cathode which reduces all metals and non-metals and produces from mercury compounds metallic mercury which forms an amalgam. Arsenic and antimony hydrides are exhausted and processed further. ADVANTAGE - This can clean large quantities of soil in a short time.
