    Laboratory Weighing - Filter Weighing

    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.

    Air quality monitoring

    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.

    Emission control & air dedusting for steel and ferrous alloys

    teel and ferrous alloys production happens in industrial manufacturing processes which involve high temperature exhaust streams, often at more than 900 ºC. Typically, the gas flows into a gas conditioning tower to cool down to approximately 200 ºC, before entering into an ESP. These flue gases from steel or ferrous alloys kilns are also very maintenance demanding for bag filters and the very small size of the particles limit the use of usual dedusters such as regular cyclones and multicyclones as pre-separators. Bag filter failure is consequently a very common problem for clients in this industry. 

    Client`s needs include a very robust dedusting system, either serving as end-stage collector avoiding the need to cool down flue gases, or strongly minimizing the loads of aggressive material to bag filters.

    Air pollution control (APC) equipments for pharmaceutical industry

    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 greatly reduced.

  • Erosion control and separation for hydraulic works

    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.

  • Odour removal units for professional kitchen ventilation

    Our company has odour removal units for professional kitchen ventilation, for grills and food preparation areas generally. The operation of the unit is based on chemical or electrostatic filters or a combination of both. The kitchen unit KDSA (with chemical filters) series, neutralizes particles, soot, odors, grease and moisture completely. KDSA units for kitchen ventilation are installed in the cooker hood and are connected with the kitchen areas that produce smoke or where there is smoke and odors such as in kitchen funnels or in washing facilities. The air stream in the deodorizer passes through a set of filters where particles, grease, soot and odors are removed.

  • High performance solid-liquid separation system for deepwell industry

    Deepwell facilities for the disposal of plant waste streams often employ nominally rated spray spun elements, bags, diatomaceous earth filters, and various other types of conventional filtration technology. These labor intensive systems provide protection of the well from occlusion by suspended particle matter, albeit often with high operational cost and limited assurance of reliable fluid quality. The ongoing challenge facing a deepwell system is the requirement that the formation into which the waste is being pumped must maintain its porous nature in order to operate effectively. Therefore, reliable, effective filtration to capture particles with the potential to plug the formation is critical. Pentair Porous Media’s proven advanced separation technologies have been employed in deepwell disposal systems to enhance system reliability, assure well integrity and lower operating costs and system maintenance.

  • High performance filtration & separation system for amine

    There are a number of factors that affect the capacity and operation of a typical amine system. Solid or liquid contaminants in the system may cause foaming. The presence of foaming is typically addressed by the addition of expensive antifoam chemicals and/or by reducing the operating capacity of the amine system. In addition to this, the presence of contaminants in the system can foul heat exchangers and column packing or trays. These solid and liquid contaminants are either ingressed into the system with the feed stream, or generated within it as a result of the chemistry of the system. These contaminants are typically addressed by means of particle filters and carbon adsorption.

  • Radionuclide Monitoring for Nuclear Power Plants

    The continuing establishment of nuclear power stations around the world pose unique environmental challenges for their operators. Ecotech provides air samplers to nuclear power plants for sampling of radionuclides. A nuclear power plant`s radionuclide monitoring network enables continuous sampling of airborne particles onto sample filters contained within High Volume Air Samplers. These filters are then analysed in a laboratory in order to screen for any radiation releases. The challenge has always been to obtain a sufficiently large volume through the filter in order to exceed the laboratory methods minimum detection limits. Ecotech`s MegaVol Sampler, samples at a flow rate of between 120-150 m3/hr providing a high flow rate in order to collect a sufficient sample mass for laboratory analysis. The MegaVol will maintain volumetric flow rate at a preset volume until the filter is either changed or overloaded. The MegaVol can be equipped with a 3G modem in order to remotely monitor flow rate and other diagnostic parameters such as temperature, pressure and wind speed and direction.

  • Filtration for Flue Gas Analysis and CEMS

    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, Temp. is around 0-180 deg C 4, Back flushing gas is heated, impulse flushing 5, Filter Material: Titanium Sintered, SS316L Sintered, PTFE sintered, Ceramic Membrane and so on 2nd Step Gas Treatment: #11;The coarse filters and the liquid particle filters The coarse and fine cartridge can filter the small particles in the gas and acid aerosol things to better protect the instruments. The micron can be 0.1micron, filtration rate can be up to 99.99%, two layers can be 99.9999%

  • Grinding & Deburring

    Grinding & Deburring dusts are Unbreathable. Many industrial processes generate contaminants in the air in the form of dust and particles. Airborne dust and fine particulate can be hazardous to human health, and should be extracted before it reaches the worker`s breathing zone.? Typical sources of these pollutants arise from cutting, grinding using an angle grinder or die grinder, automated grinding machines, deburring work and many other abrasive processes. Robotic grinding machines generally create a large volume of particulate which can require more filtration media to handle increased dust loads. Whereas other applications such as deburring can create very fine submicron particles that require the use of a high efficiency HEPA filter to capture the fines.? Metal, composite, fiberglass and rubber dust can be extremely dangerous to inhale and can be associated with many different lung conditions and health problems. Diversitech offers a diverse range of dust collectors, extraction arms, filter cleaning machines and downdraft tables for your grinding dust filtration requirements.???
