A method for preparing a filtered beverage includes filtering a raw beverage using a cross-flow ultrafiltration device to produce a solids fraction and a liquid fraction; heating the solids fraction to a temperature of 60° C. or greater to produce a pasteurized solids fraction; microfiltering the liquid fraction through a microfilter having a size cut-off of 1 μm or smaller to produce a microfiltered liquid fraction; and combining the pasteurized solids fraction and the microfiltered liquid fraction to result in the filtered beverage.

The present application relates to a preparation method for recycling inorganic salt in printing and dyeing wastewater and comprises the following process steps: S1, performing impurity removal, softening, COD removal and decoloration on reverse osmosis (RO) membrane concentrated water to obtain pretreated wastewater; S2, performing two-stage electrodialysis on the wastewater obtained in step S1: returning fresh water obtained in a first-stage electrodialysis desalination chamber to a front end of the RO process, and taking saline water obtained in a concentration chamber as raw water of a second-stage electrodialysis desalination chamber and a second-stage electrodialysis concentration chamber; and returning the fresh water obtained by the second-stage electrodialysis desalination chamber to the first-stage electrodialysis concentration chamber; and S3, dealkalizing the concentrated saline water obtained in the step S2 and then adjusting the pH value to obtain concentrated saline water capable of being reused for cloth dyeing in a printing and dyeing mill.

A plant cell co-expressing at least one casein protein and at least one kinase. The at least one casein protein is phosphorylated by the at least one kinase in vivo. Casein micelles comprising phosphorylated κ-casein and at least one of αS1-casein, αS2-casein, and β-casein can be made in vivo and/or in vitro. The casein micelles can be used to make food products including milk and cheese.

Methods of filtering a liquid feed are disclosed. In one version, the method comprises passing a liquid feed through a single pass tangential flow filtration (SPTFF) system and recovering the retentate and permeate from the system in separate containers without recirculation through the SPTFF system. In another version, the method of filtering a liquid feed, comprises passing a liquid feed through a tangential flow filtration (TFF) system, recovering permeate and a portion of the retentate from the system in separate containers without recirculation through the TFF system, and recirculating the remainder of the retentate through the TFF system at least once. The methods can be performed using an SPTFF or a TFF system that comprises manifold segments to serialize the flow path of the feed and retentate without requiring diverter plates.

Disclosed herein is a single pass cross flow diafiltration system comprising: a filtration module having; two or more filtration segments fluidly connected in series, each having an upstream side and a downstream side; wherein each filtration segment comprises hollow fiber filter membranes, and wherein each filtration segment has a selected length; wherein the hollow fiber filter membranes of each filtration segment have a selected inner diameter; wherein the selected inner diameter of each filtration segment may be the same or different, provided that at least one selected inner diameter differs from another selected inner diameter, and provided that the two or more filtration segments are arranged such that no selected inner diameter in a given filtration segment is larger on the upstream side; one or more pumps, mounted to urge fluid flow; and one or more points of introduction of a diadiluent, each of said points of introduction being fluidly connected to an upstream filtration segment.

The present disclosure provides a system for extracting long chain dicarboxylic acid, the system comprising: a primary membrane filtration unit, a first crystallization unit, a first separation unit, a first dissolution tank, a secondary membrane filtration unit, a second separation unit, a second crystallization unit and a third separation unit. By the system for extracting long chain dicarboxylic acid of an embodiment of the present invention, the resulted long chain dicarboxylic acid product has a high purity, very low and even no residual alkane residue, and organic solvent-free.
