The invention provides a method, apparatus and system for separating blood and other types of cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One of the exemplary methods includes providing a first flow having a plurality of blood components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first blood cellular component of the plurality of blood components into the second flow while concurrently maintaining a second blood cellular component of the plurality of blood components in the first flow. The second flow having the first blood cellular component is then differentially removed from the first flow having the second blood cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.

A magnetic filter (10) for a central heating system is disclosed, the filter (10) including a connection assembly (12), a canister (14), and a magnetic element (16), the connection assembly (12) including an inlet (24) and an outlet (26) for connection to a central heating circuit; the canister (14) having an interior separation chamber which is fluidly connected with the inlet (24) and outlet (26) for allowing fluid to flow into the inlet (24), through the separation chamber, and out of the outlet (26); and the magnetic element (16) being removably positionable on the outside of the canister (14), the canister (14) and the connection assembly (12) forming a sealed flow path comprising the inlet (24), the interior separation chamber and the outlet (26), and the connection assembly (12) further including a closable drain outlet (28b) for draining fluid and magnetic particles from within the canister (14), internally of the magnetic element (16).

A separator device 10 for removing particles from suspension in a fluid including a housing 12, having first and second apertures 96 for ingress and egress of fluid into and out of the housing 12; a first separator chamber 38 disposed at one end of the housing; a second separator chamber 40 disposed at the other end of the housing, and a central chamber disposed between the first and second separator chambers 38, 40, the first and second separator chambers 38, 40 being apertured for ingress and egress of fluid from the central chamber and each containing obstruction means to slow the flow of fluid within the chamber.

A machine and methods using electro-chemical treatments, sedimentation processes and dissolved air flotation technologies for clarification of several kind of wastewater produced in industries, sewages, ponds, lakes, canals etc. The machine comprises of, feeding lines with multiple feeding point, a tank and further a collection tank. The wastewater is passed into the feeding line which may comprises of several feeding points for coagulants, flocculants, and other chemicals dosing into the flow of wastewater and may also comprises of a static mixer for mixing the coagulants, flocculants, and other chemicals with wastewater to agglomerate any solid particles and to accelerate separation of the solid particles in the tank. Once the solid are formed, they can go up or down, therefore to remove the suspended solids the outlet are rearranged depending on the suspended solids. Further, the machine is used for treatment of wastewater utilising multi pass concept to produce clean water.

The present disclosure relates to the technical field of waste water treatment, and provides a device and a method for controlling diffusion of MPs (Microplastics) carried with ARGs (Antibiotic Resistance Genes) in a waste water treatment system. The device includes a water collection tank arranged on a mounting rack, a collection assembly arranged inside the water collection tank and used for collecting MPs carried with ARGs in waste water, and a treatment assembly arranged inside the water collection tank and used for removing the collected MPs carried with ARGs in waste water. According to the method, sorting treatment for the MPs carried with ARGs in waste water is realized effectively with an air flotation principle and an electric separation principle. The device is simple in integral structure, and has the advantage of convenience in mounting.

A magnetic separator for a central heating system comprises a housing, a separation chamber within the housing, and inlet and outlet ports extending from the housing. The inlet and outlet ports include push-fit connectors having collets surrounding the mouth of each of the inlet and outlet for releasing the connectors. The magnetic separator also has a release tool. The release tool has first and second bearing areas for bearing against the collets of the inlet and outlet connectors, and a handle region for enabling force to be applied, via the bearing areas, to both connectors simultaneously.

A magnetic particle separator (10) suitable for separating magnetic and non-magnetic particles from a thermal fluid flowing in a heating system. The magnetic particle separator (10) comprises a hollow body (10A, 10B) configured with an upper particle separation chamber (11) and for circulation of the thermal fluid between an inlet and an outlet port (12, 13), and a quieting chamber (15) beneath the particle separation chamber (11) for accumulation of the particles separated from the fluid: an annular support element (21) for permanent magnets (18) being removably fastened outside the quieting chamber (15) of the separator (10).

An electro-separation apparatus for separation of drilling fluids is provided. The apparatus can include a reaction chamber and a set of electrode plates provided in the reaction chamber. A sediment outlet can be provided near a bottom of the reaction chamber and wiper blades can be provided for sweeping sediment that has collected on the electrode plates towards the sediment outlet.
