particle filter Applications

For particulate matter (PM) emission control in high temperature exhaust streams, such as those from biomass or coal boilers and heaters, common dedusters such as cyclones and multicyclones are not able to comply with current emission limits. This is mainly due to their low efficiency, particularly for small particles (less than 10µm). In order to meet emission limits this usually requires an additional investment in a final stage deduster. Bag filters (BF) are very efficient dedusters. They can also be...

To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol collectors.

Several industries face problems from dust released during product transportation or processing. This is the case of the Textile, Wood Processing, Mining, Ink Manufacturing and other industries. Frequently, in order to maintain an appropriate level of particles suspended in the air (usually measured in Parts per Million by Volume), dust is extracted with air in strategically positioned caption points and typically recovered in cyclones or in bag filters.

An increasingly high number of industries, from the fine chemicals to the cosmetics industry, are investing on the design and production of nanoparticles, such as metal oxides, in specific reactors. There is a need to recover these very fine powders from the exhaust streams often at high temperature, pressure and moisture. The very fine particle size precludes the use of mechanical collectors by themselves. The main problem of using barrier filters is product hold-up and breakage of the nanoparticles. Client`s...

Three Steps of CEMS: 1st Step: Gas Sampling 2nd Step: Gas conditioning and treatment 3rd Step: Measurement/Calibration In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part. The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance 2, Filtration Grade: usually 2 or 3 micron 3,...

The dirty water is pumped by the roll round pump through the "KLASS-Grobfilter", which separates bigger particles, to the "KLASS-Zyklonfilter". The dirty water is cleaned in the "Zyklonfilter". At the exit of the dirty water the contaminated water with its particles is led back to the sludge chamber. In the return flow of the dirty water there is the "Durchflussregler", which maintains a constant pressure in the "Zyklonfilter". The cleaned water is transported in to the clean water chamber and can be used again.

Most industrial processes have dust collectors of some form or other, the most popular being filter bag houses. Very few of these are covered by regulation other than to have a broken bag detector to prevent nuisance dusts escaping and creating a local nuisance. The CODEL StakGard is a low cost Tribo-electric monitor that directly measures mass particulate concentration by sensing the frictional charge created when particles collide with a conductor. The advanced electronics of the StakGard detect this signal and...

Water scarcity and the cost of water treatment has caused an increasing interest on water reuse for municipal and industrial reuse. Water treatment require mechanical filtration such as sand and anthracite filters to retain the particles that cause turbidity. Occasionally it is also necessary to reduce water hardness through ionic exchange or the adsortion of contaminants through the use of activated carbon. Our pressure vessels are suitable for any of type of filter media: sand, anthracite, silex, ionic exchange...

Our Filters are Highly Resistant to Corrosivity. Reverse osmosis is one of the most widely applied desalination technologies. Previous to the process of separtion of water from salt and minerals, seawater or brackish wter requires the elimination of large size particles in order to assure a good performance of reverse osmosis membranes. Our sand filters facilitate the removal of these suspended solids to avoid membrane fouling. In addition, after reverse osmosis process, water has to be remineralized through...

Traffic means mobility and air emissions. Thanks to economical advantages, diesel engine becomes more and more popular, but particle emission is strictly restricted by regulations. Determining the weight of particulate matter (PM) is a key task in the automotive industry and one which is likely to become even more important as emissions standards become stricter. To allow fast and easy measurement of particulate matter at any time, METTLER TOLEDO has developed new filter weighing solutions.

The existence of prior treatments (decantation) or low efficient filtration systems, in which the quality of the filtered water depend on the parameters as flowing speed through the filtering element, from the nature of particles, frequency on which the maintenance labours are done and backflushing efficiency does not guarantee the necessary quality levels. AZUD filtration equipments turn our installation in a system with the highest guarantees of maintenance of the required quality of water.

Continuous population growth, rising standards of living, industrialization and urbanization limit the availability of fresh water. Wastewater treatment and reusage is increasingly emphasized as a method of freshwater conservation and as a means of safeguarding the aquatic environment. The Sheaf Filter can improve the common tertiary treatment practiced today, by removing fine particles in the range of 1-10 µm. This enables a constant and reliable water source, and reduces the amount of water extracted from...

The pharmaceutical industry worldwide is facing a major challenge. The productions of desired chemicals leaves an amount of by-products, some of them dangerous to both humans and the environment. An incinerator is usually used to deal with the challenge to reduce the volumes of hazardous substances. This process, however, creates sub-micron particles that conventional filter technology cannot handle. By using EnviBAT’s technology for gas cleaning – the best in the industry – such issues can be...

Any industrial work application that includes grinding and deburring is going to create dust that requires immediate filtration. Whether it is an angle grinder, die grinder or an automated grinding machine, dust and particles will pollute your workplace unless they are captured and filtered at the source. The key is to remove dust and particulate before it reaches the breathing zone of nearby workers. Depending on the nature of the work application, grinding and deburring can create airborne metal, composite,...

Tidal fluctuations and wave action can cause major damage to coastlines and off-shore construction projects. Nonwoven and specialty woven geotextiles can be used as a filter under layer beneath stone/ rock armour. Also riprap or synthetic erosion control mats are used to control erosion by disallowing the sub grade soil particles to erode. The geotextiles prevent erosion carried off by runoff water or other erosive waters, such as waves, stream flow, etc.

To separate solids from liquids, nonwoven or woven fabrics out of animal or vegetable fibers are used, and synthetic fibers are now in use since several decades. In cross-flow filtration the filtrate is recuperated transversely to flow direction through a porous wall layer. In classic filtration, a filter cake is built up on filter surface and this cake reduce the flow of filtrate which will depend of the cake permeability. Often it needs such a cake structure build-up in order to obtain a clear filtrate. The...
