Abstract
This invention relates to a belt press for dewatering sludge, such as sewage sludge. The press includes a camera to monitor physical operation of a gravity belt section of the press. A numerical control device uses electromagnetic radiation received from the gravity belt section to control the physical operation of the gravity belt section. An actuator device may be used to control a height of a weir for distribution of the sludge over the gravity belt section, and another actuator device may be used to control positions of ploughs which plough the sludge.
