Claims12
A sludge dewatering process in which a sludge product comprising water and other materials is subjected to compressive mechanical forces and electro-osmosis using a belt comprising, at least in part, electrically conductive material, wherein the belt comprises a plurality of connected spiral yarns and wherein the said electrically conductive material is inserted into and/or onto the said spiral yarns.
The use of a filter belt in a sludge dewatering process in which a sludge product comprising water and other materials is subjected to compressive mechanical forces and electro-osmosis, the said belt comprising, at least in part, electrically conductive material, wherein the belt comprises a plurality of connected spiral yarns and the said electrically conductive material is inserted into and/or onto the said spiral yarns.
