Abstract
A separation apparatus, in particular intended for separation of amalgam from water, includes a pre-settling chamber, a distribution chamber and a fine settling zone. The fine settling zone includes a plate package, with a plurality of plates fixed with spacing, forming settling channels. The plates can be machined so that they are provided with a large number of fine bumps and recesses.
Claims17
An apparatus for separation of particles from a liquid, comprising:
- a container having an inlet for particle contaminated liquid,
- a pre-settling zone in communication with said inlet for settling of coarser particles, the pre-settling zone delimited by a perforated plate extending from a top of said container to a bottom of said container,
- a distribution chamber in communication with said pre-settling zone for uniform distribution of liquid flow into a fine settling zone communicating with an outlet for purified liquid, the distribution chamber delimited by another perforated plate extending from the top of said container to the bottom of said container;
- said fine settling zone comprising at least one plate package comprising a plurality of parallel fixed plates, stacked horizontally;
- each fixed plate having at least on a top surface a plurality of bumps and recesses.
