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.

Safety filter for filtration solution application

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.

Filter technique solutions for the water recycling sector

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.

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.

Monitoring solutions for the dust collectors

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...

Pollution Solutions for Grinding and Deburring in the Workplace

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,...

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...

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.

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...

Water treatment solutions for the Drinking water & water reuse sector

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...

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...

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...

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...

Effluent filtration in textile industry

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...
