Abstract
The invention relates to a device for continuous separation of solid particles from a liquid suspension. The device comprises a tank with a separator space. According to the invention, the tank has a horizontal bottom portion located under a lamella separator, and the solids discharge device is an endless scraper conveyor arranged to remove solid particle sludge collected on the bottom of the tank. The conveyor has a portion running along an inclined wall of the tank, along which transverse scraper elements on the conveyor are arranged to slowly push the sludge up above the liquid surface in the tank to then dewater the sludge before it is fed out through a sludge outlet.
