HORIZONTAL PRESSURE LEAF FILTERS

Horizontal pressure leaf filters are ideal for solid-liquid separation involving large filter surfaces.

Simple to use and requiring little maintenance, horizontal pressure leaf filters are essentially composed of a pressure tank with filtering elements inside and a washing system.

The filtering elements consist of vertically mounted round leaves that filter through both sides.

The leaves are the same shape and size. They are therefore interchangeable and ensure ease of maintenance of the filter and uniformity of the cake.

TECNIPLANT horizontal pressure leaf filters are also equipped with a cleaning device for removal of the cake that can clean the leaves in two ways:

1. dry discharge
2. wet discharge

In the dry discharge configuration, the cake is removed with a high-frequency vibration system and is discharged through a connection flange on the bottom of the tank.

In the wet discharge configuration, instead, the cake is removed with sprayers mounted in a horizontal device that oscillates at variable speed. In this case, the device cleans the entire filtration surface with powerful jets of water or solvent.

Lastly, the filter leaves are held by a central shaft which also acts as a filtered liquid collector.
