    摘要: A process for removing silicon compounds from aqueous NaCl brine includes, first, adjusting a weak brine to a pH value of less than 3 with hydrochloric acid. Iron(III) chloride or other trivalent iron ions are added to the acidified weak brine, the obtained weak brine is then continuously fed to a stirred dissolution vessel which contains undissolved salt in addition to brine. Fresh salt is charged batch-wise and intermittently to the dissolution vessel to produce strong brine. The obtained strong brine is fed to a stirred buffer vessel, the pH value in this buffer vessel being maintained at a level ranging from 5 to 8. A strong-brine flow is continuously withdrawn from the buffer vessel and filtered, and the filtrate containing the added iron and silicon is discharged. Also a system for carrying out this process is disclosed.

    摘要: An installation for powder coating articles, in particular vehicle bodies, comprises a coating booth, in which a plurality of application devices for the powder coating may be arranged. The articles to be coated are located during the coating process on a rotating rotary stand. Application devices located in various angular positions relative to the axis of the rotary stand may be charged with powder coatings of different colors. A collecting hopper is located at the bottom of the coating booth, the outlet opening of which collecting hopper may be brought as desired into connection with various recovery devices for powder overspray. To coat articles of different colors, the application devices charged with powder coating of the appropriate color are activated in each case and the recovery device which collects the powder of the corresponding color is brought into connection with the outlet opening of the collecting hopper.
