equipmentsfeb 18, 2019 · means of solidliquid separation (mechanical dewatering): filtration, centrifugation and reverse osmosis. solidliquid filtration basics processing magazineprocess engineers must use their own kind of sleuthing in selecting the right type of solidliquid separating equipment. its not an easy task. the wide range of equipment that can be employed and the illogical solutions that are often required can cause confusion. as a further complication, only two basic principles of liquid/solid separating exist, which means equipment that might not be the ideal choice must be made to work, while admittedly sacrificing some efficiency. engineers must be particularly careful when working with suppliers that only offer one type of equipment. the solution they are offering may work but not necessarily be the smartest choice. engineers confronted with a solidliquid separation challenge must carry out their own basic evaluations of possible or probable solutions. several approaches to categorizing solidliquid separation equipment are available. first, the engineer must decide whether the process is batch or continuous. this is not as simple as it s see full list on processingmagazine the two basic principles of solidliquid filtration involve either separating liquids from solids or filtering solids from liquids, using one of two principles: 1. that the solids will have a tendency to go one way and liquids the other (separation) 2. that use will be made of a hole smaller than the solids to be captured (filtration) still, more than 100 different types of equipment are available, many with their own variations. focusing on solidliquid separation, suspended solids are removed from liquid either on the surface (cake filtration) or within the depth of the filter medium. the depth of the filter media can be the filter media itself, the cake or the filter aid. regardless of the surface of depth filtration, three mechanisms exist for removal: inertial impact, diffusional interception or direct interception. particles in a fluid have a mass and velocity and therefore an associated momentum. as the liquid and entrained particles pass through a filter media, the liquid wi see full list on processingmagazine in some cases to help the filtration process, filter aids are used to change the solid phase of the material. filter aids can range from proprietary products such as diatomaceous earth or expanded silica to randomly selected crystalline materials. in general, they are only useful in filtration processes, although in specific cases they can assist settling if the suspension solids tend to adhere to or impinge on the filter aid crystals. diatomite, perlite and cellulose are the most widely used porous media (filter aids) in dynamic process filtrations, with a high percentage of fine filtration applications using diatomite. diatomite is obtained from diatomaceous earth. this sediment is greatly enriched in silica in the form of the siliceous diatoms, which is a diverse array of microscopic, singlecell algae of the class bacillariophyceae. these diatoms are sufficiently durable to retain their structure through both long periods of geologic time and thermal processing. diatomite produc see full list on processingmagazine cellulose filter media is produced by the sulfite or sulfate processing of hard woods. cellulose is characterized by its high aspect ratio, which enables it to easily precoat a filter media. it is most often used in combination with diatomite. like perlite, cellulose possesses a less intricate structure than diatomite. other organic media includes potato starch particles, cotton linter, and polymeric fibers and flakes. these materials can help disperse diatomite in some systems or are specific to certain applications. an unusual mineral filter aid of organic origin, the ash from the combustion of rice hulls, has high silica content and a residual carbon char and is useful in waste treatment and stabilization of hazardous materials. filter aid can be used as a precoat or a body feed. as a precoat, the filter aid protects the filter media against the penetration of unwanted solids and premature blinding of the media. in practice a combination of the two approaches is most common. i see full list on processingmagazine for the purposes of this article, two main types of filter exist: media synthetic cloth or metal. the choice of media depends on filtration removal efficiency, process requirements, filter technology, characteristics of the solids and liquids, and other parameters such as chemical and thermal resistance. with synthetic cloths, the materials can be polyesternylonpolypropylenepvdf (kynar)peekor fluoropolymers, such as etfe, ptfe, ectfe, carbonized or polyester. the media can then be segmented by the degree of openness. plain, square weaves have visible or nearly visible weave openings normally larger than 200 microns and closed weave filter cloth from 1 to 200 microns. for the weave itself, warp is the lengthwise of longitudinal thread in a roll, while weft is the transverse thread. media suppliers also talk about monofilament and multifilament. monofilaments are the most concise and regular fabrics. the singular strand threads are capable of exact detail. they wear well, a see full list on processingmagazine the alternative is metal media. metal media can be single layer or multilayer and is fabricated of stainless steel and alloys, such as hastelloy, inconel, nickel, monel and titanium. single layer metal mesh is similar to the cloth weaves. other metal weaves include: plain weave twilled weave plain dutch weave twilled dutch the multilayered weaves can be sintered or unsintered. with unsintered material the interlocking of the weave is the only strength factor that prevents wire movement. sintering makes the geometry of the original weave permanent, and therefore the pore size is fixed. sintered metal media is constructed of multiple layers of wire mesh and designed for precise controlled porosity, uniform pore sizes and distribution. the laminates are permanently bonded under precise diffusion bonding (sintering) conditions. the standard designs can be two, three or five layers. the middle layer excels at removal efficiency while the top layer is protective and the bottom see full list on processingmagazine as discussed earlier, filter aids can alter the material phase of the solids. in some situations, to aid in the filtration process, it is necessary to change the effective particle size of the solids with coagulation and flocculation processes. these can only be used if the process itself can tolerate added chemicals. the suspended particles in slurry will vary in size, shape and density. coagulation and flocculation occur in successive steps intended to overcome the forces stabilizing the suspended particles and to allow particle collision and growth of solids into larger particles to help filtration. if one step is incomplete, the next one will be unsuccessful. chemically, coagulant chemicals are metallic salts, such as alum or polymers. polymers are manmade organic compounds made up of a long chain of smaller molecules. polymers can be cationic (positively charged), anionic (negatively charged) or nonionic (neutrally charged). coagulants are usually fed into the water using one see full list on processingmagazine surface charges on particles can affect the rate and extent of the filtration process. the magnitude of the actual charge is not easily measured, but the effective charge of the solids in the slurry can be characterized by the solids zeta potential. what does this mean for filtration? at times, maximum repulsive forces are beneficial to keep the particles discrete and prevent them from going into larger particles and settling. in other cases, the opposite effect is desirable because by removing the forces, the particles are allowed to grow and settle. the real answer depends upon the process conditions and application. it is important to note that the zeta potential can vary due to the ph and the ionic species strength in the slurry. for example, the zeta potential can be lowered by adding nonadsorbed electrolyte ions to the bulk slurry to promote agglomeration of the solids. of course these parameters can only be modified if they are compatible with the process. the intensity of see full list on processingmagazine 3
