    摘要： A method for treating raw milk to produce treated milk having a lower bacterial content than the raw milk. The milk is homogenized and within about 5 minutes from the homogenization, subjected to dynamic microfiltration, to yield a filtrate which has a lower bacterial content than the initial raw milk. The resultant milk can be sterile, free from Bacillus cereus bacteria that usually causes degradation of milk quality during refrigerated storage. The milk can be shipped even under non-refrigerated conditions without spoilage, for extended periods of time.

    摘要： A fluid treatment element comprises a wrap spirally wound in successive overlapping windings about the external surface of a cartridge. The wrap has a portion contiguous to a portion of the external surface of the cartridge. A first adhesive is disposed between the external surface of the cartridge and the contiguous portion of the wrap. A second adhesive is disposed between overlapping windings of the wrap. An end cap is disposed over an end of the cartridge and is secured to the end of the cartridge and an end portion of the wrap. The fluid treatment element is applicable to various fields, including, for example, filtration, water demineralization, and gas treatment.
