How a Thickener Works
Know More
Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids The early methods of thickening employed plain flat-bottomed tanks into which the pulp was fed until the tank was full The solids were then allowed to settle as long as required the top liquid was decanted the settled solids were...
