BECO® Standard Range depth filter sheets were developed to meet demanding liquid filtration requirements. The product range covers retention grades between 5.0 and 0.2 microns. Finely fibrillated charged cellulose fibers form the matrix of the BECO® Standard Range depth filter sheets.
BECODISC® Stacked Disc Cartridges are characterized by maximum purity. Comprised of the same mineral-free depth filtration material as the BECOPAD®, they support a wide range of applications including coarse and sterile filtration of all liquid media. The outer edge is coated with polypropylen and sealed. Depending on the cartridge type, a different number of stacked filter cells forms a cartridge unit. Precisely-fitting intermediate profile rings seal the space between the filter cells. The cartridge held together by a three-part segmented stainless steel sleeve that ensures excellent mechanical sealing and eliminates leakage.
BECOPAD is a mineral-free (no D.E. or perlite) depth filtration media containing only purified cellulose fiber. BECOPADs are characterized by their unparalleled purity when compared with conventional filter sheets. With very low extractable ions, the pads will not impart any undesirable taste in your product.
Diatomaceous earth (DE), is a filtration media composed of microscopic diatoms silica structures millions of years old. DE is used in the beer industry as an extremely effective economical filtration media to facilitate liquid-solid separating. DE’s uniquely strong cylindrical shape, high pore volume and low resistance to flow make it the go-to filter medium.
Application: Two-step operation; first added as a protective layer (pre-coat), and then to maintain porosity (body-feed in pressure filters).
Packaging: 50 lb. bag & 1000 kg super sack
Chemically inert complex filter aids which are used in the formation of precoats for continuous dosing filtrations. Fiber Floc is specifically formulated to contain highly purified alpha cellulose and cotton fibers (zeta-potential) in addition to perlite. Fiber Floc 10 is recommended for primary filtration and Fiber Floc 30 is recommended for polish filtration.
Application: Usually added as the initial pre-coat then followed by either DE or Perlite.
Packaging: 35 lb. bag.
Perlite is a lightweight expanded bubble structures from volcanic glass that are milled and classified into powders that are used in both pressure and vacuum filtration equipment. Perlite filter aids are inert and will impart no taste or odor into wine, and are virtually insoluble in mineral and organic acids at all temperatures. Various grades are available, so please contact an ATP rep about your particular need.
Application: Usually added as a filtration aid during filtration or as a pre-coat at the start of the filtration cycle.
Packaging: 25-35 lb. bag depending on grade.
