FILTER PRESS (SPARKLER TYPE)

HORIZONTAL FILTER PRESS is a sparkler type and consist of S.S. Shell & Top cover using bolts to give pressure tight enclosure. The filter cartridge assembly inside the shell consists of several horizontally arranged disc type filter plates with perforated supporting screens, filter media & interlocking cups. The entire assembly complete with pump & piping connection is mounted on a suitable S.S. Trolley.

STANDARD FLOW TYPE : The impure liquid to be filtered is fed to the filter shell by pump. It arrives on top of each plate through opening on the sides of plates. As liquid pressure increases, the filter media (Paper/fabric) holds back the impurities & allows the crystal clear filtrate to pass through the central channel (formed by interlocking cups) which takes the filtrate to the outlet of filter. This filter most commonly used to obtain clear liquid. However if required, the cake formed between the plates can be obtained. Filtration is continued until its rate becomes very slow due to increased cake resistance.

SALIENT FEATURES :

Manufactured in S.S. 304 / S.S. 316 / S.S. 316L M.O.C • M.S / S.S. Jacket can be provided for hot filtration.
Gives crystal clear filtration by filtering particles up to 1 micron size.
Scavenger arrangement to remove all the liquid.
Cake can be dried either by compressed air or by insert gas, steam.
Filtration rates from 600 Ltrs/hr. to 30000 Ltrs/hr possible depending on the models.
Centrifugal / Gear / Lobe pumps can be offered, which can also be used for liquid transfer.
Sample collecting device & safety valve provided.

FILTER PRESS (SPARKLER TYPE)

REVERSE FLOW ZERO HOLD UP TYPE : Here the direction of flow of liquid is exactly opposite to the flow in standard filter i.e. the impure liquid to be filtered enters the filter from the bottom into the center channel & goes to the top of each plate. The clear filtrate flows out from openings on side of plates to the shell & then to the outlet. This flow ensure almost 100% filtration of the liquid which is not so with the standard flow type.

SALIENT FEATURES :

Complete filtration of the batch without any hold up due to reverse flow of liquid hence large saving in time & cost.
Back wash facility can be provided for continuous operations.
No scavenger arrangement required.
The cake, filteraid & solids remain totally enclosed allowing filtration of toxic, hazardous & explosive liquids.
No contamination of internal surface of shell.
The top dome structure ensures fast & easy removal of cartridge assembly & cleaning of cake.
Other features same as standard flow type.
