Abstract

Procedure and device for dehydration by filtration of sludge or similar substances, especially in sewage treatment plants or similar; characterized in that the sludge or the like is continuously dehydrated, in successive phases independent of each other and that the parameters of the respective phase, such as pressure, speed, filter size, etc. They are adapted to the properties of the mud or analogue that vary during the dehydration process.
