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 Confilt
Compared 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 conditions
Alfa 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. The unique design of the automatic filters with continuous back flushing prevents adhesion of retained solids to filter surfaces and guarantees long life cycles and low maintenance costs. For more than 40 years, the Alfa Laval Moatti filters have been protecting engine and sensitive mechanical devices in various environments all over the world, in power stations, large vessels, locomotives and trucks. Alfa Laval Moatti has also developed a strong relationship with OEM diesel engine builders, seeking reliable and effective filtration solutions for their diesel engines.
W Sil - The self cleaning strainer
The Alfa Laval W-Sil is a self cleaning strainer that consists of a stainless steel housing, a perforated basket (different size of mesh are available between 50µm and 3mm) and a shaft with stainless steel brushes. The self cleaning strainer is most often used for the continuous removal of solid particles from many process industry streams, including the food and chemical industry.
Membrane filtration systems
At Alfa Laval we know how membrane filtration technology can be applied in order to optimize the performance of a process. This is based on more than 35 years of experience in the design, manufacture and installation of membrane filtration systems.
Plate & Frame modules
Alfa Laval’s Plate & Frame modules are available in three different channel heights for different viscosities enabling choice of the most cost effective solution in terms of energy consumption and versatility. The modules are approved for sanitary operation and offer great advantages when product purity is paramount. In addition, being a “clean” technology, membrane filtration leaves no residue of any kind in the product.
Tailor-made solutions
Alfa Laval designs, manufactures and installs turnkey membrane filtration systems based on either plate & Frame modules or on spiral elements. We maintain a close dialogue with our customers throughout the process and become deeply involved in aspects such as industrial applications, process requirements, technology options and choice of membrane. All sides of a project are dealt with.
Test your needs
At Alfa Laval we appreciate how inconvenient it can be, in terms of time and raw materials, to test new processes within the context of day-to-day operational processes. That is why we offer state-of-the-art pilot laboratory equipment to help our customers assess their specific needs.
In order to ensure the optimum solution it is often advisable to conduct experiments on a small scale. These can be used for a number of purposes including:
- Establishing process feasibility
- Determining design data for scale-up, i.e. final product composition, operation parameters and cleaning procedure
- Optimizing existing production lines by testing the influence of change on products or processes
- Small scale processing of high value/low volume products such as hormones vaccines and peptides
Pilot plant equipment
Alfa Laval provides pilot laboratory equipment both for testing on site in connection with other process equipment and for testing at our own state-of-the-art pilot facilities in Nakskov, Denmark. In both cases, we also provide highly skilled process consultancy services.
