Belt dryers

Belt dryers comprise a conveyer belt which is fed with the dewatered sludge. The sludge solids are slowly transported by the belt through a stream of heated air, generally at 80-180 °C. They permit an additional element of process control to the usual parameters of sludge feeding rate and heat input, since the belt speed can be adjusted to change the dryer residence time.
