  3. Decanter centrifuge - Wikipedia

    en.wikipedia.org/wiki/Decanter_Centrifuge

    The decanter centrifuge cannot separate biological solids with very small density differences, such as cells and viruses. [5] A competitive process that is capable of separating these difficult-to-separate solids is the tubular-bowl centrifuge. The machine can be very noisy and can cause vibration.

  4. Microwave chemistry - Wikipedia

    en.wikipedia.org/wiki/Microwave_chemistry

    Specific microwave effects are those effects that cannot be (easily) emulated through conventional heating methods. Examples include: (i) selective heating of specific reaction components, (ii) rapid heating rates and temperature gradients, (iii) the elimination of wall effects, and (iv) the superheating of solvents. Microwave-specific effects ...

  5. Extraction (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Extraction_(chemistry)

    Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte moves from the initial solvent into the extracting solvent.

  6. Liquid–liquid extraction - Wikipedia

    en.wikipedia.org/wiki/Liquid–liquid_extraction

    A separatory funnel used for liquid–liquid extraction, as evident by the two immiscible liquids.. Liquid–liquid extraction, also known as solvent extraction and partitioning, is a method to separate compounds or metal complexes, based on their relative solubilities in two different immiscible liquids, usually water (polar) and an organic solvent (non-polar).

  7. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.

  8. Microwave oven - Wikipedia

    en.wikipedia.org/wiki/Microwave_oven

    A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating .

  9. Centrifugal water–oil separator - Wikipedia

    en.wikipedia.org/wiki/Centrifugal_water–oil...

    In a centrifugal oil and water separator, the force of gravity is one-thousand [citation needed] times greater that of the coalescing plate pack separator or the petrol interceptor, so the separation is much greater. Not only is the force of separation greater, but there are fewer working parts so maintenance is much easier and cheaper. [5]
