  • Ready, set... mix: water re-use and its role in concrete mixing

    Water is a key element to the concrete ready-mix manufacturing process. From mixing new concrete to cleaning out trucks, high volumes of water are in demand. To stay ahead, many operations, large and small, are prepared to re-evaluate their process to find opportunities for water re-use. A filter press is an effective piece of equipment for concrete water recycling. It separates ...

  • To prevent blinding in dust collection systems, consider filter type, filter size and selection of the filter media used

    All dust collection systems, regardless of size, share a common problem—dust blinding. Simply stated, blinding is defined as when dust particles plug the holes in a filter and stop the flow of air through the filter, resulting in the dust collector performing poorly. All types of collectors, whether stand-alone units, cyclones or full-scale baghouses, are subject to blinding. To better ...

  • Solid / gas separation with fabric filters

    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 ...

  • Water contamination problems solved at automobile air bag manufacturing plant

    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 ...

  • Particles and alkaline compounds - Case Study

    Example: Refining of bauxite Similar tasks: Metallurgy The production of aluminium oxide during the Bayer process - as a raw material for the aluminium industry - is done by refining the bauxite with sodium hydroxide solution. For better economic efficiency, the sodium hydroxide re-circulates in a circular pattern. Part of the highly contaminated sodium hydroxide is ...

  • Crusher and milling machine in stone processing industry

    Stone processing mainly includes crushing and grinding. Both methods are used to reduce the size of or powder industrial rocks and minerals by crushers or grinding machines, which are called Stone processing machines and equipments. After processing, the stone or rock can apply in construction, building, highway and some chemical industries. Crusher is to make bigger stone (30mm~1000mm) smaller ...

  • Filter technology to meet evolving regulations

    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 25-year long monitoring of lead content in the blood of cows from a stationary polluted area

    The monitoring has been performed on lead content in the blood of cows (n = 1,279) from farms (n = 1?14) near a former lead mine and current smelting plant from 1975 to 2003. Early measurements showed that average lead concentration in the blood of cows was 1.25 ? 0.58 mg/kg while in 2002 it was about 10-times to 20-times lower (0.069 ? 0.005 mg/kg). Significant decrease in blood lead ...

  • Case Study: Heavy Industrial Laundry

    This facility washes heavily soiled towels from the ink printer and furniture polishing industries. The wastewater generated is very concentrated with metals and hydrocarbons making it difficult to treat in their DAF pretreatment system. The facility was using conventional chemistry with sulfuric acid, organic/inorganic coagulant, metal precipitant,flocculant, and Harborlite (filter press ...

  • Fine particle capture in biomass boilers with recirculating gas cyclones: Theory and practice

    This paper addresses the theoretical development and experimental validation of optimized recirculating reverse-flow gas cyclones. The simulation of these systems is based on the predictive properties of a finite diffusivity model, modified to include partial recirculation of the cyclones' emissions. Experimental validation was obtained at laboratory and pilot scales at low temperatures (up to ...

  • Laboratory, pilot and industrial-scale validation of numerically optimized reverse-flow gas cyclones

    This paper addresses the experimental validation of the optimum design of reverse-flow gas-cyclones, obtained through the solution of a numerical non-linear optimization problem, viz. maximizing cyclone collection. The simulation model is based on the predictive properties of a finite diffusivity model, where the particles' turbulent dispersion coefficient is estimated through an empirical ...

  • Pilot and Industrial-Scale Experimental Investigation of Numerically Optimized Cyclones

    A new geometry of reverse-flow gas cyclones obtained by numerical optimization was shown at the laboratory scale to be significantly more efficient than other high-efficiency designs. However, it is usually recognized that experimental results obtained with laboratory-scale or sampling cyclones cannot be extrapolated to pilot or industrial scales. The present paper confirms, at these larger ...

  • Advantages and basic facts for the use of Lenzing PROFILEN based filter media

    Normal PTFE filter bags have a very good chemical resistance but on the other hand they do not have a high dust separation efficiency. Lenzing PROFILEN® is a compromise between a high efficiency and a high flow rate after cleaning of gases with all the positive aspects of normal PTFE bags. Basics To acquire a better feeling and understanding for the advantages of Lenzing PROFILEN® it is necessary ...
