Moving Bed Carrier

A: There are so many positives to a moving-bed bio filter, with perhaps the only significant downside being that they tend to do very little to de-nitrify the water, and that is something that can be remedied, to a resonable degree, with a trickle tower or bakki shower, downstream of the moving bed filter.

A: These carriers named K1 media have a large surface for air, bacteria and contact water. The activated sludge, which is also the bacteria grows on the internal surface of the carriers.

A: The advantages of using a packed bed reactor include the high conversion of reactants per unit mass of catalyst, relatively low operating costs, and continuous operation. Disadvantages include the presence of thermal gradients throughout the bed, poor temperature control, and difficult servicing of the reactor.

A: In a counter-current moving bed reactor, a continuous stream of solid sorbent particles moves downward under the influence of gravity, contacting a rising gas stream in a counter-current manner. Temperature swing desorption of CO2 is considered in this work.

A: Fluidized-bed reactor produces 26–38 % more light chemicals (C5–C10) than fixed-bed. LDPE requires severer pyrolysis conditions (>520 °C) for a complete pyrolysis reaction. ABS oil is mainly composed of aromatics (72 %) whereas PP includes paraffins and olefins.

A: The pellets used in fluidised bed reactors are expected to be smaller in size than that used in packed bed reactors in order to ensure the ability to fluidise the solid and because using larger pellets will consume relatively more energy.

A: The most important characteristic of a PBR is that material flows through the reactor as a plug; they are also called plug flow reactors (PFR).

A: The MBBR process is based on the activity of microorganisms that attach to and grow on large surface porous solids called "CARRIERS", which float in the wastewater medium. The fundamental role of the carriers is to provide a protected surface for the growth of "biofilms".
