  • The Phase 1 Environmental Assessment

    In today’s world where every property is subject to potential environmental risks a Phase 1 Environmental Site Assessment or ESA is an appropriate action to take. An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property.  Lenders ...

  • What are the best companies for Zero Liquid Discharge Equipment and Technology?

    With an increasing push for environmental protection, many industrial facilities and effluent regulators are making decisions that lessen their impact on the environment and human health. Changes and implementations are constantly being discussed and met both nationally and internationally to change the way industrial facilities discharge waste, and it is important to know which companies are the ...

  • 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 ...


  • Technical Resources for Gas-Phase Air Filtration

    Gas-phase air filtration is a highly specialized branch of air filtration with a very short list of reputable and knowledgeable companies manufacturing the dry-scrubbing media, filters, and systems in which they are employed. The list becomes even shorter when considering where to go for the ...

  • Case study - Organic particulate filtration

    Overview A food products company that mixes various types of waxes and other components to make the base for chewing gums was faced with the issue of cleaning up a slightly odorous, visible emission being exhausted from two of their process lines. The components of the emission were hot particles of chewing gum and some volatile organic compounds (VOC's). The particles would quickly clog ...

  • Peristaltic pumps for moving filtration water

    The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents and is one of three plants operated by the city of Osnabrück in northern Germany. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant's capabilities. To deal with this situation, engineer Peter Sikora organized a team ...

  • Keeping Water Soft -- Next Generation Filtration for the Oil & Gas Industry

    There is a need in many segments of the oil and gas production industry for an improvement in water filtration over traditional methods. This is especially true since the trend in oil and gas production is toward tighter, less permeable reservoirs and greater use of Enhanced Oil Recovery (EOR) techniques, many of which involve injecting water into oil reservoirs. In order to protect ...

  • Dewatering waste-activated sludge using dissolved gas-flotation followed by filtration

    After the successes of flotation of waste-activated sludge (WAS), using the new technique utilizing CO2 gas as well as using model gas (80% N2+20% CO2) in previous research because of the high water solubility of CO2 gas, the aim of this study is to develop a simple method for dewatering WAS for easier reuse and safe disposal. The paper introduces a laboratory model for dewatering WAS in two ...

  • Hydraulics stability of compost-based filtration media

    The longevity of compost-based storm water filtration systems has not been widely studied. Hydraulic conductivity measurements of compost amended sand media (20% and 50% v/v) within columns were undertaken. The results show that the filtration media in both columns had a reduction in the total saturated hydraulic conductivity. A tracer test showed there was no blockage due to biological or ...

  • Produced water filtration optimization case study

    Pentair Porous Media has worked with a major global oil & gas producer to optimize the performance of the filtration and separation at their United States mid-continent operations located in the Wind River Basin of Central Wyoming. Their operations cover more than 42,500 net acres in Wyoming. Net gas production averages greater than 100 MMSCFD from multiple formations ranging in depth from ...

  • Rolled Filters Move Filtration in a New Direction

    When selecting filtration technology, industrial users have long wrestled with the tradeoffs of dirt-holding capacity versus particle selectivity or quick-and-dirty change-outs versus process time. For many applications, a self-contained rolled filter offers an effective solution to both problems. Constructed with polypropylene hardware and various media in a spiral-wound design, rolled filters ...

  • BHP Billiton - cooling water treatment & solids filtration

    Client: BHP Billiton Douglas CETCO Oilfield Services was requested to supply a water treatment package to treat heavily contaminated water in-line.
