SALTEC Belt Thickener ( BT ) is a gravity belt thickener machine, with a fully enclosed system and act as a first dewatering stage. It is designed to work either as separate thickening equipment or together with SALTEC – ScrewPress. It can also be used as a combo version consisting toghether with a Belt Filter Press. The machine does separate sludge and water due to gravity as well as static filtration. The filtration is a very gentle process which means that the sludge does not break at any point.
The ploughs are designed to enable the opening and turning of the sludge. This means that the sludge is drained more efficiently. In the beginning of the belt, SALTEC has developed a “V” shaped sludge collector, which contributes to a more even flow out on the belt. At the end of the belt, the sludge is dammed up by an adjustable sludge ramp to provide a longer drainage time for the sludge
