SYNTHETIC FABRICS FOR LIQUID FILTRATION DURING INDUSTRIAL PROCESSES

Synthetic fabrics for filters produced by SAATI ensure very high precision standards for all liquid filtration operations. These comprise wastewater treatment (residential or industrial), purification of oils and emulsions, and multiple dehydration processes/mud treatment in various industrial processes for miscellaneous applications (food, chemistry, mining, etc.). Design and production of precision fabrics progress alongside the option of providing fabrics in either finished or partly finished products, to ensure better performance and processing efficiency. Moreover, equipment especially designed for SAATI, combined with our expert know-how in various fields, allow us to provide fabrics cut to order and customised high quality parts in a wide range of shapes.

SOME OF OUR ACCOMPLISHMENTS OVER THE YEARS

Filtrer Press

Filter
Press.

Filter presses were introduced at the turn of the century and have been around for many years mainly dewatering waste sludges. They were considered labor intensive machines hence they did not find much acceptance in the sophisticated and highly automated process industries. It was not until sometime in the 60's that this image has changed by the introduction of advanced mechanisms that were oriented towards obtaining low moisture cakes that discharge automatically and enable the washing of the cloth at the end of the filtration cycle.
The Filter press consists of a head and follower that contain in between a pack of vertical rectangular plates. Each plate is dressed with filter cloth on both sides and, once pressed together, they form a series of chambers that depend on the number of plates. The entire pack of plates is supported by side or overhead beams.

Rotary vacuum drum filter (RVDF) is one of the oldest filters used in the industrial liquid-solids separation. It offers a wide range of industrial processing flow sheets and provides a flexible application of dewatering, washing and/or clarification.
A rotary vacuum filter consists of a large rotating drum covered by a cloth. The drum is suspended on an axial over a trough containing liquid/solids slurry with approximately 50-80% of the screen area immersed in the slurry.
As the drum rotates into and out of the trough, the slurry is sucked on the surface of the cloth and rotated out of the liquid/solids suspension as a cake. When the cake is rotating out, it is dewatered in the dying zone. The cake is dry because the vacuum drum is continuously sucking the cake and taking the water out of it. At the final step of the separation, the cake is discharged as solids products and the drum rotates continuously to another separation cycle.

The Candle Filters are, as all pressure filters, operating on a batch cycle and may be seen in process lines handling titanium dioxide, flue gas, brine clarification, red mud, china clay, fine chemicals and many other applications that require efficient low moisture cake filtration or high degree of polishing.

Candle Filters are also used for thickening to produce a concentrated flowable slurry by partial removal of the liquid phase as filtrate. This mode of operation is possible since Candle Filters may operate on very short cycle times taking advantage of the high filtration rates whilst the cakes are still thin. One of the features of Candle Filters when used for thickening is their clear filtrate since gravity, thickeners, in analogy, produce overflows which always contain a certain amount of fine suspended solids.
