  • The Filtration Spectrum

    Reverse Osmosis. Microfiltration. Distillation. Deionization. With so many types of filtration and purification systems on the market today it is difficult to determine which type of technology is best for your needs. The filtration of liquids is performed at many levels. To understand how to maximize your filtration needs, one needs to consider the size range of the particles. Once this is ...

  • Wastewater Treatment Using Crossflow Filtration Technology

    Introduction It does not take a great deal of effort these days to recognize the attention being given to water availability and purity. If in a position of consumption, obtaining just a minimum supply is a struggle in some geographical areas. In other areas available water is tainted with contaminants making it unsuitable for use. Further, those fortunate enough to have ample supply in the ...

  • Different Biological Water Filtration Systems

    Do you know what’s in your water? Most people don’t. It’s recommended that you drink at least a half-gallon of water each day. If it’s not purified or filtered, that water could be causing unseen damage to your body. Arsenic, salmonella, streptococcus, and influenza viruses could all be present in your tap water. There are many different forms of biological filtration that ...

  • Fibra™ technology for filtration and neutralization of concrete wastewater

    Multi-Purpose Process Fibra technology, now available in the US market, provides an innovative solution for the treatment of concrete wastewater, a traditionally difficult to treat effluent with high pH and a variety of fine suspended contaminants.

  • Economic and Environmental Benefits Flow From Filtration Technology

    Crossflow filtration operations typically fall into one of four categories: microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and hyperfiltration more commonly known as reverse osmosis (RO). The most common of the operations is reverse osmosis due to its ability to remove dissolved impurities including dissolved salts. Crossflow filtration machines typically include the membrane ...


  • Downflow filtration technology keeps contaminants at bay

    Just south of present day Lumpkin, GA, you can visit a reconstructed community from the 1850s and experience a taste of everyday life from that time period. In dramatic contrast, you will also find one of the water and wastewater industry’s most advanced filtration technologies in this same area. This technology was installed specifically to protect the Lumpkin area from the damaging effects of ...


  • Electropositive filtration technology in automobile manufacturing applications

    Argonide Corporation began as an organization focused on the production and sale of nanopowders. By definition, nanopowders are extremely small particles (less than 0.1 micron) of materials such as nickel, copper, iron, alumina, gold, etc. These materials are in demand by research and development groups within both the public and private sectors. To date, the company is still involved in this ...

  • City Water International explains The Basics of Water Filtration

    The Basics of Water Filtration Most of us know that filtered water is healthier than tap water because of its purity, but how does water filtration work? The basic principle is that filtered water has passed through a filter which removes contaminants through one of several methods, depending on the type of filter. Most water purification systems work in one of three ways ­ by running water ...

  • Water filtration media: Talking about a revolution?

    Developments in any field of endeavour are nearly always evolutionary, not revolutionary. It is normal to expect advances in manufacturing equipment, process control and chemical science to facilitate product improvements. In the field of liquid filtration there is frustration at the seemingly unbreakable linkage that exists between increasing pressure drop and lower flow rates as gains are made ...

  • 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 ...

  • Tailings filtration - case study

    YEAR: 2009 COUNTRY: MEXICO N° and MACHINERY MODEL EMPLOYED: 3 GHT 2000.P13 MEM Diemme® Filtration The customer, a silver Mine in Mexico, had just started up a new 3500 t/d cyanidation plant to increase its silver bar production to 115 t/y.

  • Revolutionary Filtration Put To The Test

    There are many cool aspects of my job, not the least of which is learning — and sometimes even breaking news — about the latest technologies in oil and gas. When I heard from Mike Dejak, executive VP of Eco-Tec, that the company's new technology could "revolutionize filtration" for the produced water market, I was anxious to learn more about it. However, I was also duty-bound to you, ...

  • Membranes, the Finest Filtration

    Introduction The notion that salt could be removed from seawater without a phase change took hold of Dr. Sourirajan's imagination in the late 1950's. The actual invention of the reverse osmosis (RO) membrane took place in his laboratory at UCLA around 1960. (Thus Sourirajan could be called not only the 'Father of Reverse Osmosis,' but the initiator of all crossflow membrane technology.) The full ...


  • Understanding Crossflow Filtration

    There's a lot of attention being given to water availability and purity, with good reason. Obtaining enough water is a struggle in some areas. In others, water is tainted with contaminants. It is therefore predictable that regulations and economics will force careful water treatment and stress water re-use. Fortunately, there are water treatment methods that can help you meet the water quality ...


  • Water treatment technology for produced water

    Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined ...
