The Facility Based in a Rocky Mountain state, this facility produces the sodium azide pellets contained inside the air bags for automobiles produced throughout the world. The Problem During the manufacturing of the air bag propellent, frequent equipment washdowns produce large volumes of wastewater that contain sodium azide and metal sulfide salts. Sodium ...
A cartridge dust collector uses filtering cartridges and is a self-cleaning dust collector. The cartridges it uses are made from synthetic fibers and cellulose that is treated chemically. This ensures the particles are efficiently collected without forming an excessive pressure drop in the system. Structure A cartridge dust collector uses an air-jet cleaning structure to preserve ...

Given their unique performance attributes membranes are finding use in a growing number of high efficiency air filtration applications. One example is in respirators and personal protective equipment. Applications where intense physical demands and risk of exposure to harmful contaminants are present demand the high efficiency / low pressure drop combination of expanded polytetrafluoroethylene ...
Maguin has developed the Cercat filter for high temperature air pollution control. In this article, David Gambier and Hélène Real outline the technology, as well as installations planned for 2009. Maguin has been present in the waste thermal treatment field since the 1970s. The company’s knowledge has been built through the turnkey supply of thermal treatment units for different kinds of products ...
A myriad of filter media are utilized today for separation of particulate matter in industrial gas filtration applications. These media range from single use (deposable) to semi-permanent media and include fiber, fabric, ceramic, membrane, metal mesh, and sintered metal media. Semi-permanent media are usually cleanable, either on or off-line, and are primarily intended for long-term (up to ...
Pollutants are nothing but any substance that may present in an atmosphere in such a concentration that it may harmful to surrounding, living organism or human being. Sampling and analysis of air pollutants is known as Air quality monitoring and it is major part of environmental monitoring. There are many advanced types of ambient air Sampling methods. we will learn here only which are most ...
Mercury is a dangerous neurotoxin that can have damaging affects on both the central nervous system and renal system of humans. Exposure to mercury can cause serious developmental delays in children, and high level exposure is life threatening. When exposed to air, mercury vaporizes, readily becoming a dangerous aerosol that can be absorbed into the lungs and spread throughout the body. This is ...
Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury"s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once ...
M-Series breathers are designed from heavy-duty materials capable of handling the requirements of the most severe environments. They replace the standard breather ...
The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring on average 54 cubic meters of water per metric ton of finished product. As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water ...
Electrostatic precipitation has been a reliable technology since the early 1900's. Originally developed to abate serious smoke nuisances, the manufacturers of zinc, copper, and lead quickly found electric gas cleaning a cost efficient way to recover valuable product carried out of the stacks from furnace operations. Today electrostatic precipitators are found mainly on large power plants, cement ...

The operation of filtration type arrestment plant can be optimised by the effective use of Particulate Emission Monitors (eg Filter Leak Monitors and Filter Performance Monitors). Particulate Emission Monitors are installed throughout the broad spectrum of industrial processes to satisfy regulations (IPPC, Part B Guidance Notes, WID and LCPD) for emission limit enforcement. In addition, where ...
When it comes to choosing a cartridge filter, the choice usually depends on the application. Systems with finer particles require a cartridge filter, and these come in the choice of two. Surface and Depth-Type Filters A surface filteris ideal when filtering remains of similar-sized particles. Depth-type filters capture pollutants and particles ...
ABSTRACT: Background The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In order to clean a row of bags in a reverse pulse jet baghouse first the flow of filtered air must be momentarily stopped and then back flushed or “induce” air to knock the dust cake off the outside of the filter media. A venturi at the top of the ...
ABSTRACT: Background The reverse pulse jet baghouse has been around for over 45 years and the cleaning cycle has not changed very much since that time. The cleaning cycle is the most important part of the dust collector because it controls efficiency and media life. In a generic baghouse, the cleaning system is comprised of a blowpipe that is located typically approximately three inches above ...
This technical paper will explain the new nozzle technology developed by Scientific Dust Collectors that allows high air-to-cloth ratio baghouses to use 80psig of compressed air instead of the industry standard 100psig. The reverse pulse jet baghouse has been around for over 50 years and the cleaning cycle has not changed very much during that time. The cleaning cycle is the most important ...
