  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...

  • Using Nanofiltration in Beverage Production

    The following article is based on a paper presented in August, 1990 at the 21st Annual Meeting of the Fine Particle Society in San Diego. Soft drink manufacturers, not to mention manufacturers of other beverage products, have always had a keen interest in the water that goes into their products. After all, it is the water that typically makes up 80%-90% of the product. In the past the water has ...

  • Fibra™ lets Tarmac reuse water & meet EA discharge requirements

    Innovative Features Following a period of continuous growth, full-scale FibraTM filters have been installed at two Tarmac pre-cast concrete sites for removal of contaminants from wastewater. The solution has proven particularly effective at other similar sites and other comparable industrial applications. These industries have traditionally discharged the wastewater to sewer because it has ...

  • Non-woven electrostatic media for chromatographic separation of biological particles

    The filtration and separation of biological particles has been estimated as 40% of the cost in the manufacture of pharmaceuticals. Liquid chromatography that is the principal method for separating biological particles uses a permanent phase of ultrafine adsorbent particles such as porous silica or resin spheres with particle sizes down to about 1 micron. Speed and resolution are two competing ...

  • Particle removal efficiency of Nano alumina fiber filters

    A 2 nanometer alumina fiber is combined with a microglass fiber to produce a nonwoven filter. Its pore size is 2 microns, yet it is functionally rated at 0.03 microns. Data are presented showing dirt holding capacity and filtration efficiency for particles from 0.001 to 7 microns. The filters have high retention for micron size silica dust, bacteria, virus, DNA/RNA, tannin and latex spheres. ...

  • Application of Membrane Technology for the Recovery and Reuse of Water

    ABSTRACT As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...

  • MPT CASE STUDY: Improvement in Quality of Product at a Fine Chemicals Manufacturer

    The Opportunity A major manufacturer of fine chemicals experienced quality problems with a neutriceutical product they produced. The product, like all FDA approved products, has very high standards of quality. The company experienced occasional off-spec batches ...


  • Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management

    It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost of ...

  • Moving difficult-to-handle bulk materials with flexible screw conveyors

    Flexible screw conveyor systems can be engineered to transport bulk materials that tend to pack, cake, smear, break apart or fluidize, and can prevent the separation of blended products. Flexible screw conveyors (Fig. 1) are suitable for most bulk materials, from sub-micron powders to large pellets, both free-flowing and non-free flowing. They are capable of conveying bulk materials at any angle ...
