Disclosed is a system and method for treating municipal and sanitary wastewater that uses only mechanical devices and processes, which eliminates biological processes and settling tanks. The system includes a three-output Richter-type separator that separates wastewater into three fluid streams according to the specific gravity of the solids within the fluid streams. The lighter-than-water and heavier-than-water solids streams are combined and the resultant sludge is mechanically dewatered without intermediary biological-process systems or sedimentation. The partially-clarified water component can be directly filtered by a membrane filter and optionally optically or chemically disinfected for reuse or disposal. The system advantageously simplifies municipal and sanitary wastewater treatment eliminating traditional primary and secondary treatment stages, and significantly reducing the system's operational footprint. The system and method can be scaled to very large municipal systems.

Contaminants present inside an ultrapure water production system are prevented from being fed into a feed pipe connected to a water use point and, after sterilization cleaning, the system is prevented from being contaminated by contaminants captured on a microparticle removal membrane during sterilization cleaning. Ultrapure water having high quality is thereby fed to a water use point within a short period of time. An ultrapure water production system is provided with a tank, a pump, a heat exchanger, an ultraviolet device, an ion-exchange device, a first microparticle removal membrane device, and a second microparticle removal membrane device. Parts of sterilization water and flush water are fed into the first microparticle removal membrane device and discharged from a feedwater-side potion to a concentrated-water-side portion without permeating through a microparticle removal membrane thereof, and the remaining part of the water is passed through the second microparticle removal membrane device.

A reverse osmosis system comprises a permeate collection tube which is connected at one end to a distribution system for permeate which comprises at least one device for cleaning and/or disinfection. The permeate collection tube, the cleaning and/or disinfection device and a circulation pump are arranged in a circulation circuit.

A process for concentrating a maple sap or sweet vegetal water solution is provided. The process comprises collecting the solution in a tank at temperature T1, wherein T1 is between 4? C. and 10? C.; concentrating the solution by means of a reverse osmosis concentrator to produce a high Brix solution of about 15 to about 40 Brix; heating the high Brix solution of about 15 to about 40 Brix to temperature T2, wherein T2 is between 40? C. and 85? C.; and evaporating the high Brix solution by means of a vacuum evaporator at temperature T3 to produce the concentrated product of about 60 to about 70 Brix, wherein T3 is between 55? C. and 80? C. A system for concentrating a maple sap or sweet vegetal water solution is provided, as well as a concentrated product produced by the process of the present invention.

A liquid containing exosomes is filtered through a first filter that has a hole diameter that passes the exosomes and blocks cells, and is then stored in a first storage unit (rough filtration step). Next, pressure is applied to the inside of the first storage unit to pump the liquid to a pre-filtration chamber in a second filter that blocks the exosomes so that water in the liquid is filtered out into a post-filtration chamber. The exosome-containing liquid that was not filtered out is returned to the first storage unit, thereby increasing the exosome concentration in the liquid for extraction (concentration step). The exosome-containing concentrate in the first storage unit is then filtered through a third filter having a hole diameter that passes the exosomes and blocks bacteria, and is sent to a recovery unit (sterilization filtration step).

The present invention relates to a potentiated T-cell modulator (TCM), with a potency of 10.sup.12 leucocytes/mm.sup.3, obtained from a dialysed extract of leucocytes from the spleen of Selachimorpha or sharks that contains peptides equal to or less than 10,000 Da, in powder form. The invention also relates to the use of the TCM to produce a medicine for treating diseases related to the regulation of immune response such as cancer or viral infections.

In order to improve the lifespan of the semi-permeable membrane or the yield of the reverse osmosis system in the treatment of drinking water by means of reverse osmosis, the invention provides a device for treating drinking water with at least one reverse osmosis vessel which is divided into at least two chambers by at least one semi-permeable membrane, wherein a first chamber has an inlet for the water to be treated and an outlet for the concentrate, and the second chamber has an outlet for the treated water, wherein the device comprises at least one pressure vessel which is connected to the outlet for the treated water via a line, wherein the device is designed in such a way that, in an idle state, treated water flows out of the pressure vessel, through the semi-permeable membrane and into the first chamber.

The invention relates to a process for treating animal skim milk and sweet whey and/or acid whey, having: (a) ultrafiltration (UF1) of a first liquid composition including animal skim milk with 70-90 wt % casein and 10-30 wt % whey proteins, based on total protein, over a first ultrafiltration membrane having a molecular weight cut-off of 2.5-25 kDa using a volume concentration factor of 1.5-6 to obtain a retentate (UFR1) and a permeate (UFP1); (b) ultrafiltration (UF2) of a second liquid composition including sweet whey and/or acid whey over a second ultrafiltration membrane having a molecular weight cut-off of 2.5-25 kDa using a volume concentration factor of 2-15 to obtain a retentate (UFR2) and a permeate (UFP2); and (c) mixing the UF retentate originating from step (a) with the UF retentate originating from step (b) to obtain a mixture of UF retentates.
