Multi-Media Filter with Flow Rate of 3m3/H

Filtration Process

Vessels with sand or other loose filtration media are used in AES industrial filtration applications.These filters are cleaned by backwashing the media.During a backwash cycle, the filter bed is lifted and fluidized to remove accumulated particles.After the backwash cycle, the filter bed is allowed to settle.While it settles, the filter bed media will classify with the heaviest media particles settling first, and the lightest particles settling on the top.A single media (sand) filter bed will classify differently than a multi-media filter.Since all sand particles in a single media bed have approximately the same density, the largest particles are heaviest, and the smallest are lightest.Larger/heavier particles settle at the bottom, while the smallest/lightest particles settle on top.While this does not provide very efficient filtration capacity, since filtration occurs mostly at the upper surface of the filter bed where the spaces between media particles are smallest.However, due to the formed filtration cake on the top of the filter, smaller and smaller particles can be prevented from passing through, which results in a better outlet quality.Dual media beds use two or more filtration media.The media have selected densities to ensure that the bed settles in a more efficient manner.Anthracite, the largest particle, is the lightest (least dense) and settles on top.It provides large pore spaces that trap larger particles while allowing smaller particles to travel through to the layers below.Sand is intermediate in size and density.It settles as the middle layer.The sand layer filters out particles of intermediate size while allowing smaller particles to flow through to the gravel layer.Gravel, the heaviest (most dense), settles out as the bottom layer in a filter vessel.A dual-media filter needs fewer backwashing for a given volume of water filtered.The filtering capacity is significantly increased for the same volume of media as compared to a single media bed.The whole bed filters, not just the surface.



Actived carbon filter

Activated carbon filters are typically used to remove organic compounds and/or free chlorine from water to make water suitable for use in manufacturing or discharge.Removing organics like fulvic and humic acid from potable water prevents these acids from chemically reacting with chlorine to form a class of carcinogens known as trihalomethanes.
