An adsorbent for a target compound can include porous carbon particles having pores with a predominant pore size less than 10 nm, and magnetic nanoparticles (MNP) nucleated on the carbon surface and within the pores of carbon particles to provide a carbon magnetic nanoparticle adsorbent (C-MNA). A method for removing target compounds with an adsorbent, a system for removing contaminants from a liquid, and a method for adsorbing target compounds from a fluid are also disclosed.

A method and apparatus for extracting active components from a plant material by: introducing the material containing the active components in an extraction chamber: introducing a hydrofluorocarbonated compound in a tank at a pressure between 482.6 kPa and 1,447.9 kPa (70 psi to 210 psi): introducing ethanol in a receptacle; mixing the hydrofluorocarbonated compound with ethanol; allowing the mixture to reach the plant material; allowing the mixture enriched with ethanol and the hydrofluorocarbonated compound to flow out of the extraction chamber and into a tank; allowing the ethanol to evaporate and become separated from the residual mixture slower than the hydrofluorocarbonated compound; optionally, the hydrofluorocarbonated compound is recovered by condensing and returning it to the pressurised tank; optionally, the ethanol is recovered by condensing and returning it to the mixing receptacle.

The invention relates to valve system for controlling a process fluid within a liquid processing system. The valve system comprises a valve arrangement, a pneumatic control system, and a connector unit. When the valve arrangement is connected to the connector unit, two or more valves are formed, such that the pneumatic control system controls an open/close or pressure control mode of the valves. A pump diaphragm system is disclosed, as well as a system for purifying a biological material that comprises the valve system or the pump diaphragm system. Also discloses are methods of using the valve system or the pump diaphragm system in a process for the purification of a biological material.
