  • Advances in String-Wound Sediment Filter Cartridges

    In the mid-1930s, the first string-wound depth filter cartridge entered the U.S. market. It was made from a woven wire mesh core surrounded by a cotton yarn, which was wound to form the depth filtration medium. The yarn itself was a tightly twisted medium and the major filtration essentially took place at the points of crossings of the yarns- which formed a diamond-shaped pat-tern-rather than ...

  • Performance and quality analysis of membrane cartridges used in long-term operation

    In this study, operation and maintenance performance in two long-term operating Membrane Bioreactor (MBR) wastewater treatment facilities were investigated. One facility in Japan started its operation in 1999 showed that both effluent BOD and n-hexane extracts were less than 5 mg/L, and a cumulative replacement percentage (CR%) of membrane cartridges was 7.8% as of 2008. Another facility in the ...

  • Determining pesticides in dietary supplements with QuEChERS extraction, cartridge SPE, and GCxGC-TOFMS

    Regulatory requirements are driving the development of new multiresidue pesticide methods for dietary supplements. Minimizing matrix interference is critical for data accuracy. The novel approach employed here combines QuEChERS extraction, cartridge SPE cleanup, and GCxGC-TOFMS analysis, and results in good recoveries across a range of compounds found in these complex matrices. ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...

  • Pleatable UPE membrane media in pulse-cleaned dust removal air applications

    Media Selection For initial tests, three media were selected for comparison. These structures are all designed for use in pulse-cleanable cartridges, with processing on blade pleaters. Arioso™ M7001-11 is a Solupor® ultra-high molecular weight polyethylene (UPE) membrane designed for F9/MERV16 efficiency at very low resistance laminated to a 200 gsm, stiff, high permeability ...

  • Research papers: safe use of Microbubbles for removal of RO Membrane Fouling - Case Study

    For full downloadable report Abstract The authors have shown a dramatic improvement in cleaning efficiency when effervescent cleaning reagents are used in conjunction with bubbles created using a specially designed microbubble generator. One potential problem associated with this new technique ...

  • RO Feedwater: Treat It Right

    Summary Crossflow membrane filtration systems, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF), are good alternatives to traditional filtration and chemical treatment. However, to get the best performance from them, careful attention must be paid to feedwater conditions. Pretreating feedwater can lengthen the life of membrane elements, improve the quality of the ...

  • What is a slurry pump

    Talking about slurry pump, we see slurry first then next is pump, so let’s start with slurry. Slurry is a kind of liquid with solids, mostly its specific gravities greater than 1. The solids size may vary from a few micrometers, often referred to as microns, up to hundreds of millimeters and the solids may settle below a ...


  • Thermal Treatment Technologies

    Hot gas decontamination: Hot gas decontamination is a technology still in the pilot-scale of development that can be used for decontamination of explosives-contaminated masonry or metallic structures. The method involves sealing and insulating the structures, heating with hot gas stream to 260 °C (500 °F) for a prescribed period of time, volatilizing the explosive contaminants, and destroying ...

  • Getting Comfortable With Your Reverse Osmosis Machine

    Introduction Most people who work with an apparatus unlike any in their previous experience approach it with some apprehension. This is common behavior and fits the way most of us approach unfamiliar things. Perhaps you deal with this kind of uncertainty about the reverse osmosis (RO) machine in your dialysis unit. This article is intended to increase your understanding of the machine and how it ...


  • Waste Minimisation and Recycling: Fletcher Construction Australia

    A test project involving simple, practical waste minimisation and recycling measures, has helped Fletcher Construction cut its waste removal cost by more than half. The measures did not involve any capital cost, but they have resulted in substantial savings to both the company and the environment: savings of 55% were achieved on waste removal costs through recycling and input reduction, which ...
