FilterPress

Filterpress

Filterpress is the most efficient solution for solid-liquid separation. Due to the simple and economical operation, filterpresses are used nearly since 100 years in many industries.

The filterpress consists of a number of filter plates hanging on a steel construction and pressed by two pressure plates. One of the pressure plates is fixed and the other one is moveable by a electro-hydraulic mechanism.

Each pair of filter plate, when pressed towards each other, forms a chamber for filter cake formation.

After the plates are pressed towards each other at the required pressure, the solid-liquid mixture is pumped inside the filterpress by a centrifugal, membrane or piston pump, or by a combination of these as required by the application. The liquid can flow through the filter cloth while solid particles stay inside the filterpress and start to build a filter cake.

When the cake is dry enough, the feed pump is stopped, the plates are opened and the filter cake is discharged.

Filterpresses are widely used for:

· Dewatering of ceramic slurries (kaolin etc.)

· Mineral dressing and preparation

· Dewatering of electrolytic slurries

· Dewatering of industrial or municipal wastes

· Reclaiming the cooling water in marble processing

· Dye and pigment production

· Food and beverage and production

· Petrochemical and pharmaceutical industries. The price differs according to the plate size and number.
