A method for producing products, advantageously solvents, is by fermentation, advantageously multi-stage fermentation. The fermentation is complemented with pervaporation as in situ product recovery technology, combined with a multistage condensation of the permeate. The condensates are separately introduced in the downstream processing to recover the produced products, advantageously solvents. The method for producing products, advantageously solvents, by fermentation is simplified and has an overall improved energy efficiency. A related system uses method for producing products, advantageously solvents, is by fermentation.

The present invention relates to a separation of viruses of an essentially spherical shape from viruses with a rod-like shape that are comprised in a sample, wherein the sample comprising the viruses is subjected to filtration.

The present application provides a method for extracting an extractable component from a feed liquid using a porous membrane. One embodiment of the method includes temperature-swing solvent extraction of water from saline water using a porous membrane.

The present invention discloses a process for preparing high-purity raffinose from defatted wheat germ comprising the steps of percolate extraction of raffinose from defatted wheat germ, decoloration by extraction from the abstraction liquid, electrodialysis desalination, impurity removal by simulated moving bed, concentration and crystallization, with the absolute purity of raffinose as high as 98% and the recovery up to 75%. The process is not only reliable and easy to operate, but also easy to realize industrial production and control the parameters.

A reverse osmosis desalination system for treating feed water, the feed water containing minerals, the system comprising a reverse osmosis unit comprising a first reverse osmosis stage (21) and a second reverse osmosis stage (22), each of the reverse osmosis stages (21, 22) having a feed water input, a product water outlet and a brine outlet, and a fluidized bed crystallizer (30), configured to remove minerals from the water, wherein the fluidized bed crystallizer (30) receives brine from the first reverse osmosis stage (21) and passes treated water to the feed water input of the second reverse osmosis stage (22).

A resource recovery method includes: feeding raw water to a first-stage raw water tank; supplying high-temperature vapor to a first-stage heat exchanger; performing heat exchange between the supplied high-temperature vapor and the raw water in the first-stage raw water tank, changing a portion of the water into vapor and supplying the changed vapor to a subsequent-stage heat exchanger; repeatedly performing the performing step for each of the raw water tanks sequentially in the order from a second state to a n-th stage; being feed to a crystallizer from the n-th stage raw water tank; detecting a turbidity of the raw water fed to the crystallizer from the n-th-stage raw water tank; and extracting crystals of valuable resources contained in the raw water fed to the crystallizer from the n-th-stage raw water tank when the turbidity of the raw water becomes a predetermined value.

It is an object of the invention to provide a process for producing an organic acid, comprising: providing an incoming stream containing an organic acid and impurities; subjecting said incoming stream to a step of chromatographic separation, using a solution of mineral acid as an eluent, so as to collect an extract and a raffinate, the organic acid being recovered in the extract; and subjecting the raffinate to an electrodialysis step, so as to collect a diluate and a concentrate, the mineral acid being concentrated in the concentrate. The invention also provides an installation for implementing this process.
