LIQUID FILTRATION
HIGH PRECISION. EXCEPTIONAL QUALITY.
LIQUID FILTRATION
Products & Servivces
With our continued drive to achieve zero-defects, Crosible has become a world leader in the supply and manufacture of filter press cloths, filter plates, filter presses, and other liquid filtration services and solutions.
LIQUID FILTRATION
MEDIA
Process efficiency at the filtration stage lies with the correct fabric selection. Polymers, thread counts, yarn type, weave pattern and permeability all play a crucial part to achieve these efficiencies demanded by todays demanding filtration processes.
Over and above the filtration fabric, Crosible has invented unique ways of superior cloth assembly. Fusing rubber necks to achieve leak free & Abrasion resistant feed ports.
Crosible’s unique “Montini “ inlay has revolutionized challenging plate sealing applications. All filter cloth are precision laser cut to ensure accuracy and constancy.
LIQUID FILTRATION
OVERVIEW
Crosible understands the importance of paying careful attention to every aspect of the filtration process and this has been the driver for constant improvement in the materials we use and the construction of our filtration solutions.
-
RUBBER NECKS
Rubber Evoprene necks are sewn into the feed ports to combat aggressive abrasion and premature wear in the neck area. Various sizes are available for the various thickness and port diameters. -
CLOTH NECKS
All cloth necks are latex coated to render them impermeable and help core cleaning during cycles. Double neck tapes are supplied and yarn sealed with late blue sealant to ensure ultra fine particles don't slip through the neck cloths. -
LATEX EDGES
Blue Laltex is painted on the edge of some press cloths to help seal the press and reduce the whicking of liquid from between the filter plates. The Blue Latex is resistant to most mineral acids and the alkalis.
-
EYELETS
All eyelets are inserted hydraulically to ensure stable tight fitment on all the top and sides of the cloths. -
HEAT SEALED EDGES
All cloth edges and corner port edges re heat sealed to prevent fraying, and render a stable uniform size when manufactured. -
YARNS
All yarns used to manufacture filter cloths are of the same polymer as the filter cloths to comply with the chemical resistance of the liquids being filtered. -
PICTURE FRAME SEAL
When plates are worn and dont seal very well, a needle felt picture frame is cut out and sewn on the edges of the filter cloth to reduce the leaking.
FREQUENTLY ASKED
QUESTIONS
Yes, blue latex edges seal and help reduce & eliminate wicking of the effluent between the filaments, and thereby substantially reducing press dripping & leaking.
Cake moisture increases when the cloths are blinding. Therefore, selecting a media to reduce blinding reduces cake moisture.
Monofilaments, or Mono/ multifilament cloths prevent blinding hence reducing cake moistures.
A: Polypropylene is the most economical and versatile polymer, tolerating a pH from 0 to 14, and temperatures up to 90 Degree C .
B: Polyester is used for increased tensile strength and higher temperatures & higher oxidation levels.
C: Nylon (Rilsan) is used to combat high temperatures and high abrasion and achieving improved cake discharge .
To reduce cloth edge leaking, but mostly to protect filter cloth from premature failure from the plates during high filtration velocities.
It also helps with creating better drainage on the filter plates.
A: They are abrasion resistant, rendering longer lifespan to filter cloths if cloth necks fail prematurely due to abrasion.
B: Rubber necks render a leak free design, especially when fused and not sewn to the filter cloths, eliminating stitching holes.
C: The core plug of the cake is easily removed during the cleaning cycle, due to the non-drainage aspect.
A: When clarities are compromised due to cloth wear.
B: When cloths are blinded, causing slow filtration rates and moist sloppy cakes.
C: On average between 2-3 months, but if abrasion is severe or plates are compromised this could be reduced to 1-2 months. It is not uncommon to exceed a cloth life of 12 months or more, depending on the use and cycle times of the process.
