摘要： A process for the preliminary treatment of a metallic workpiece before coating is disclosed. The surface to be coated is cleaned with a solution containing a degreasing agent and coated with a corrosion-inhibiting layer. In order to obtain particularly advantageous conditions, the invention proposes that the surface of a workpiece to be coated be treated with a solution of polyaspartic acid to apply a corrosion-resistant coating.

摘要： The invention concerns a method and an apparatus for producing a metal hydroxide, in particular magnesium hydroxide, from a salt solution, wherein the metal is firstly precipitated from the salt solution and the suspension produced in that way is then filtered. The object of the invention is to provide a method and an apparatus which permit simple inexpensive and rapid production of metal hydroxide, in particular magnesium hydroxide, in a high state of purity. According to the invention that is achieved in that the suspension is filtered through at least one filter (13-17) of a cross-flow filtration installation (13-17), and that a permeate produced by filtration of the suspension is fed to the cross-flow filtration installation (14-17) again.

摘要： There is described a method of processing waste water, in particular from malt factories and breweries, which in the operational use is contaminated with microorganisms, salts and organic compounds. To enable a reuse, it is proposed to subject the waste water to a reverse osmosis after a treatment with activated sludge, before it is recirculated to the operational use.
