Filter media control the filtration process. For a particular slurry, the filter media determine whether the filtration will produce a cake, capture particles within the depth of the media, whether the particles in the slurry will clog the media, or whether the media will be ineffective in particle removal. Filter media come in a wide range of materials and forms. Some of the major types are listed in Table 1. A successful filter medium often requires a combination of various properties, as listed in Table 2. A discussion of these properties is provided by Purchas (4) and Purchas (5). In addition to the above forces ,there are secondary mechanisms that may also be applied directly cause the separation or indirectly to enhance one of the other methods . magnetic: magnetic fields are very useful for separating iron and magnetic ores . they can efficiently remove submicron-sized particles . the magnets require periodic cleaning to remove the captured particles. Capital and operational costs can be high and are directly related to the strength of the applied magnetic field .the main advantage is that separation is highly efficient and can be carried out at high flow rates with minimum head loss across the filter.

Filter media control the filtration process. For a particular slurry, the filter media determine whether the filtration will produce a cake, capture particles within the depth of the media, whether the particles in the slurry will clog the media, or whether the media will be ineffective in particle removal. 過濾介質(zhì)控制過濾的過程。對特定淤泥,過濾介質(zhì)決定是否過濾將形成泥餅,在過過濾介質(zhì)的深度值內(nèi)俘獲顆粒,是否淤泥中的顆粒會阻塞介質(zhì),或者是否介質(zhì)將對顆粒的去處無效。 還是挺容易的。樓主應(yīng)該先翻個大概,看有什么問題,再來問。 |
