Centrifugal separation
Centrifugal separation The need to separate different liquid phases and solids from each other is part of practically every industrial process. Alfa Laval has more than one hundred and twenty years of experience in meeting this requirement using either decanter or disc stack centrifuge technology, and our products perform this crucial function exceptionally well. The product range is based on disc stack centrifuges and decanter centrifuges for separating liquids from each other or for removing solid particles from liquids. These products are used for many different functions in the food and other process industries, on board ships to purify fuel and lubricating oil, on oil platforms to separate oil and water, in manufacturing industry to clean industrial fluids, and for industrial and municipal sewage treatment. Decanter centrifuges Separating solids from liquids plays a key role in countless industrial, food and treatment processes. Decanter centrifuges from Alfa Laval perform this crucial function exceptionally well. The basic physics behind the decanter is the natural settling action that gravity forces on suspended solids. Nevertheless, waiting for nature to do its job often takes too long. Matching customer needsAlfa Laval has become the market leader in decanter centrifuge technology. Our know-how and specialist process experience put us in a unique position to match the exact needs of each customer for each particular application and installation. With different design, lengths and cone geometries, our range of decanters can be applied in any processing environment that requires a separation step between solids and liquids. Alfa Laval decanter centrifuges provide meticulous control, low cost and high reliability. Centrifuge systems - modules Decanter technology from Alfa Laval can be applied to many processes that require solids separation from liquids and in many cases a decanter system can be the most cost effective solution. By combining our core competencies within separation, centrifuge systems have been developed with a plug and play attribute. This gives the advantage of lower lead times and easier installation procedures when capacity extensions or additional lines become necessary. Decanter centrifuge systems such as the ALSYS 400 for dewatering sludge, the LYNX 40 for drilling mud and others have been proven in the field again and again as a standard solution to different oil solid separation requirements. Other centrifuge systems have also been developed for protein recovery and other product recovery duties. Stand alone units With the widest range of decanter centrifuges that are equipped with leading edge technology and the highest standards in design and manufacturing, Alfa Laval decanter centrifuges are the clear leader. Our range consists of several bowl diameters, of which some sizes are available with different design, lengths and cone geometries. Alfa Laval has perfected the decanter to separate solids from liquids, liquids from liquids and a mixture of all three phases. Disc stack centrifuges With a clarifier or settling tank, particles and liquid phases, will fall to the bottom, but the lack of control and the length of time required makes natural settling unsuitable for modern industrial processes. In essence, a disc stack centrifuge is a clarifier whose base is wrapped around a centre line. Rotating this unit rapidly means that the effect of gravity is replaced by a controllable centrifugal force – the effect of which can be more than 10 000 times greater than gravity on solids suspended in liquids. When subject to such forces, the denser solid particles are pressed outwards against the rotating bowl wall, while the less dense liquid phases form concentric inner layers. The disc stackThe key to good separation performance lies in the efficiency of the disc stack, the heart of the centrifuge, therefore the design of the disc is crucial. Alfa Laval has the expertise needed to match the demands involved in specific industrial processes. 2-Phase 3-PhaseDepending on the separation requirements disc stack centrifuges can handle solids in three different ways, from liquid/liquid separation (both 2-phase or 3-phase applications) to the separation of slurries having a solids content approaching 30% (normally 2-phase applications). Nozzle bowl centrifuges Many liquid processes contain relatively high levels of solid content and when high throughputs are required with solids content of more than 10% the continuous discharge effect created by nozzles in the periphery of the bowl is put to use. The Nozzle bowl centrifuge is most often used for classification of solids according to size, dewatering and washing of solids, and for clarification of liquids containing relatively high concentrations of solids. It can also be used for 3 phase applications where two liquid phases and a solids phase need to be separated in one step. If the concentration of the solids varies over time a recirculation system can be added to the design of the centrifuge in order to gain greater control over the separation procedure. Solid wall bowl centrifuges The solid wall bowl centrifuge is designed to retain solids within the disc stack centrifuge and is closest to the original cream separator developed by De Laval. The solid wall bowl centrifuge is often used in processes that require liquid/liquid or liquid/solids separation when the solids content in the feed is no more than about 1% by volume. Because of the simplicity of the design, very high g-values can be obtained and this centrifuge is thus very efficient in the recovery of fine particles. Self cleaning bowl Many processes require solids to be discharged intermittently during operation, or for processes with liquids containing higher solids content (up to approx. 10%) the intermittent solids discharge centrifuge is an ideal solution. Designed with a unique hydraulic system below the separation space in the bowl which forces the sliding bowl bottom to drop down, thus opening the solids ports at the bowl periphery at preset intervals. This provides what is known as a self cleaning effect when the solids are removed all at once during operation. This design has vast applications in all industries and is one of the most common types of disc stack centrifuge for Alfa Laval.

Drum thickeners The ALDRUM thickeners are a range of mechanical sludge thickeners that work on the principle of conveying poly-electrolyte treated (flocculated) sludge through a slowly rotating drum filter. The sludge remains in the drum, while the water phase passes through the filter cloth. The ALDRUM Drum Thickeners are designed to handle sludge extremely gently, it gives exceptionally high recovery for nearly all sludge types. The ALDRUM thickeners are available as separate components or as part of a complete sludge thickening module, the ALSYS Thickener module. The Alfa Laval Filter The Alfa Laval Filter, is the ideal solution for protecting systems that use low quality water. For protecting heat exchangers that use seawater as the cooling media for example, the Alfa Laval Filter is the best insurance to prevent damage caused by impurities such as sea creatures and debris. In a cooling system incorporating a plate heat exchanger and an Alfa Laval Filter, polluted or corrosive water can now cool even the most sensitive process equipment. Alfa Laval Filter is also equally well suited for use with other process liquids for which filtration is required. Alfa Laval Filter is a self cleaning pressure filter with an automatic flushing arrangement. Alfa Laval Filter has the inlet directly in line and the outlet at a 90° angle; it is therefore suitable for installation on any 90° angle bend in proximity to the equipment to be protected. Advantages Solves most fouling & clogging problems in natural water sources Does not disturb operation The pressure filter combines high capacity with low pressure drop Offers full flow rate while preventing surface fouling caused by diminished flow velocity Mounted directly in the pipe system Few moving parts Alfa Laval Filter comes with a standardised control panel Confilt The Confilt module from Alfa Laval consists of a two-step separation system where two components, a strainer and a hydrocyclone, act together for the continuous removal of solid particles. The Confilt is very reliable in removing heavy particles from thick fluids such as remelt or standard liquor, in the sugar industry. Confilt can be used for other applications requiring filtration in mechanical and chemical industries. Comparing the ConfiltCompared to traditional frame and cloth filters, the Confilt requires neither cloths nor filter aid like kieselguhr, perlit or others. This means a clean, continuously working station, designed in stainless steel and ceramics, fully automated, with pneumatically operated valves. Confilt is also extremely compact in comparison to the space requirement for a frame filter station. Moatti self cleaning filters Filters for the toughest conditionsAlfa Laval’s range of fuel and lube oil filters are mostly known by the trade name Moatti, and are designed to above all, protect your diesel engine systems from harmful particles.
