Action: Xerogel has a molecular moisture content of <10%. It adsorbs haze forming proteins which eliminates that fraction from the Protein/Tannoid Complex, the major cause of non-biological post-filtration turbidity.
Additional Notes: Optimal addition would be after the aging vessel before the filter, however, it can also be added to the aging vessel provided a sufficient sedimentation period is assured. Optimal dosage temperature is 43° F or below with good dispersion and a minimum contact time of 4 minutes. This product is dusty. From the PQ Corporation.
