Action: Hydrogel has a molecular moisture content of ~ 67%. 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 32° F or below with good dispersion and a minimum contact time of 20 minutes. This product is non-dusty. From the PQ Corporation.
Typical Dosage Rates: 12 – 15 lbs/100 bbls
