The most visible form of rangeland degradation in Namibia is bush thickening also called bush encroachment on huge tracts of land. The finely balanced grasstobush ratio of a savanna has been severely disrupted in a bushencroached rangeland (Skarpe 1991). Bush species such as Acacia mel

Working of a Thickener. Let us understand in detail about how thickeners work. To start with it works on the principle of Gravity sedimentation and the most common construction of a thickener


thickener using a low head axial pump to drive dilution water into the feedwell. The main advantage of the Forced Dilution system is that it takes the overflow liquor from a large surface area negating the risk of causing localized high internal rise rates. The system then optimally mixes with the feed to produce

supernatant and flocculant. The principle of dilution is simple yet plausible. It minimises the collision of particles thus lessening the effect of hindered settling. The upstream processes produce thickener feed that in most cases benefits from dilution thereof. Laboratory scale testwork provides the optimum feed solids percentage.

How a Thickener Works

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 flatbottomed 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
