  • A Case for Point-of-Use RO Ultrapure Water Systems

    ULTRAPURE WATER CRITERIA - AN OVERVIEW 'Pure water' is a relative term. Practically speaking, no water, naturally occurring or treated by man, consists solely of H2O molecules. Forever in pursuit of achieving equilibrium with its surroundings, water has unique characteristics that result in its ability to dissolve most matter. This property of water to dissolve and transport materials is ...

  • Membrane filtration

    Membrane is a thin layer of material that is capable of separating compounds as a function of physical and chemical properties when a driving force is applied across the membrane, which has been widely used in a wide range of applications in water industry [1]. Membrane can be classified by the range of compounds separated and the driving forces employed. For example, microfiltration (MF), ...

  • 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, ...

  • Fundamentals and Advantages of Screen Filtration

    The “art” of filtration utilizes many methods for separating solid particles from fluids. There is often no right or wrong method. Water quality and customer requirements usually determine the “best” method for each unique situation. Ridged screens, pleated cartridges, string wound cartridges, melt blown cartridges, woven fabrics, non woven fabrics, sintered metals, granular media, frizzy balls ...

  • Air filtration applications for membranes

    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 ...

  • 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 ...


  • Filtration and manganese removal

    Manganese removal through a filter bed is generally carried out and accepted by practitioners and researchers as occurring through catalytic oxidation at the surface of MnO2 coated media, although manganese passage through a coated media filter has been little investigated. To better understand the kinetics of Mn removal through a naturally coated filter, a pilot plant consisting of four filter ...

  • 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 ...


  • 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 ...
