Volute Sludge Dewatering and Thickening

Volute is structured with a filter element that consists of two types of Rings: a Fixed Ring and a Moving Ring; and a screw that thrusts the filter element and transfers and pressurizes the sludge. The gaps between the Rings and the screw pitch are designed to gradually get narrower towards the direction of sludge cake outlet and the inner pressure of the filter element increases due to the volume compression effect, which thickens and dewaters the sludge.

Two types of core units

Volute is the standard technology that brought innovation to the industry of dewatering equipment in 1991. The self-cleaning mechanism that dewaters and prevents clogging has enabled continuous dewatering for a long period of time.

Advanced Volute inherits the merits of the standard Volute technology and has evolved further. Advanced Volute technology widens the range of applications in terms of sludge types, reduces the performance degradation caused by aging, and delivers stable performance over a longer period of time. In addition, the amount of components that needed to be regularly replaced is reduced sharply, reducing the total lifetime cost.
