The ESTRUAGUA Sludge thickener COTRAC is built in stainless mesh AISI 304 of triangular section and parallel to the axis. The sludge that must be treated is introduced in the inside of the drum by a distribution box and a double conducting channel.
The filtered liquid crosses the holes while the purged dregs are brought to the exit of the debris by an internal helicoidal band.
The dryness and the productivity are a function of del incoming flow and the conditioning and type of sludge. The capture index of these is excellent.
The ESTRUAGUA thickeners are closed and compact.
All parts in direct contact with the effluent are in stainless steel or in plastic materials.
