WASTE TREATMENT DEVICE

A waste treatment device may include a solid-liquid separator which is configured to receive and separate waste into solids and liquid. The waste treatment device may further include a solids treatment arrangement which is configured to receive the solids from the solid-liquid separator, wherein the solids treatment arrangement comprises a disinfection unit having a heating mechanism configured to heat, without burning, the solids so as to disinfect the solids to convert the solids into pathogen-free-treated-solids. The waste treatment device may further include a liquid treatment arrangement which is configured to receive the liquid from the solid-liquid separator and to treat the liquid so as to convert the liquid into pathogen-free-effluent. The solid-liquid separator may include a curved-funnel-shaped inner separator surface and a frustoconically-shaped inner liquid guide surface whereby the respective narrower ends are directed towards each other.

20210153527 · 2021-05-27 ·

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.

Irradiated membrane for cell expansion

A membrane for cultivating adherent or suspension cells, in particular adherent cells. The membrane permits adhesion and proliferation of the cells due to the irradiation of the wet or dry membrane with gamma or beta rays or an electron beam in a dose of from 12.5 to 175 kGy in the presence of oxygen. The resulting membrane may be used without any pre-treatment with surface-modifying substances. A method for preparing such an irradiated membrane for cultivating adherent or suspension cells. Methods of using such a membrane for cultivating adherent or suspension cells.

Sterile containers for medical objects

A holding clip is designed to be fixed in a holding contour of a housing part of a sterile container and/or to be removed from the holding contour without tools. The holding clip has at least one at least partly spring-elastic clamping section designed to provide a clamping force to secure the identifying element and at least two holding sections that adjoin the clamping section on both sides and that are designed to engage into an undercut of the holding contour in a form-fitting and/or force-fitting manner. A sterile container can include such a holding clip.
