Gravity Belt Thickener GBT drains water from sludge. Thickening is an effective dewatering pre stage to greatly save volumes for transport and to increase efficiency of digestion & dewatering. Typically a 0.4-0.8% ds wet sludge is thickened to 4-8% ds. This give huge savings by reducing the water content and volume by 90%. The wet sludge is pumped and gently spread out on top of the GBT filter belt. The filtrate water drains through the belt and the thickened sludge drops of at the end of the belt. An hygienic enclosed spray cleaning system on the inside of the belt system keeps the belt from clogging.
