Press filters


This system is used when the amount of sludge generated is greater. It is usually located high, on a structure. It consists of a robust frame that contains high-density polypropylene (pp) plates lined with filter cloth. One of the ends is mobile and is connected to a piston actuated by a hydraulic pressure group.

Its operation is as follows: the hydraulic pressure group exerts the force through the piston against the plates, thanks to this pressure the sealing of the plates is achieved. A pump introduces the mud inside the plates, due to the pressure to which it is subjected, the water is filtering through the fabrics and exits through the water outlet holes in the plates, leaving the mud inside compacted and practically dehydrated. To achieve greater dryness, we inject compressed air through the moving head and with this we manage to clean the feed collector and further dehydrate the cakes. Once compacted, the piston opens the plates and the mud cakes that have been created are precipitated by gravity. This equipment is equipped with an electrical panel that allows automatic or manual operation (to carry out maintenance work).

GTM standard plate sizes are:

The number of plates ranges from 10 to 160 approximately.
