  • The Importance of Dewatering

    With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game.  Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • Why is Energy-from-Waste slow to catch on in the U.S.?

    Nithin Coca reports in TriplePundit that Energy-from-Waste (EfW) is growing fast in Europe and parts of Asia. But it’s relatively stagnant here in the United States. In fact, the percentage of waste we burn for energy is actually slightly down in the past five years. What’s holding the U.S. back from this potentially sustainable solution? This stagnation is even more ...

  • Revolutionary advances in safer tube and pipe machinery can be a direct result of the evolutionary nature of product development.

    It’s remarkable how fast changes occur in devices we utilize in our everyday lives. Living in an era of seemingly boundless innovation, new products are introduced and then continuously refined by driving forces such as competition, regulation, improved technology, liability, labor, material costs, and consumer demand. Amazingly, many life-defining inventions can progress from a creative ...

  • Mono nov working hard with zok international

    These cleaning solutions require delicate handling i.e. pumping, mixing and filtering to produce a pure solution with no aeration or foaming, which would interfere with the accurate metering and dosing of the chemicals involved. The Compact C progressing cavity pump, ith its gentle shearing action and capacity for handling viscous or difficult to handle fluids, forms a central part of the ...

  • Soft or hard market, what lies ahead

    The past three years for the U.S. economy have been some of the worst in recent memory. Companies have struggled for survival resulting in layoffs, acquisitions, bankruptcies, restructuring and, in many unfortunate cases, the closing of shop doors. This trend has not been lost on insurance carriers, and is one of the primary reasons we are currently experiencing a “soft market.” ...

  • What is so hard about drainage modeling?

    Drainage modeling often suffers from the misconception that it is simple, but while it appears obvious that rain water will flow to the lowest point, the physical processes involved are not always well-understood or predictable. Drainage models attempt to predict that part of the water cycle that involves rainfall and its consequences, including potential flooding. Although flooding is, at its ...

  • Effect of water hardness and pipe material on enhanced disinfection with UV light and chlorine

    Limited studies have been conducted to evaluate synergistic benefits between disinfectants, although promise has been shown between ultraviolet (UV) light and chlorine-based disinfectants. This research aimed to determine drinking water quality factors that affect potential for enhanced removal of heterotrophic bacteria due to synergy between UV light and free chlorine. An additional goal was to ...

  • Hard tissue samples as markers of occupational exposure in a phosphate fertiliser plant

    This paper describes the results of study on testing of hair and nails samples as possible markers of occupational exposure in a phosphate fertiliser plant. The key objectives were to verify if: (1) elements originating from fertiliser production may accumulate in hard tissue and hence allow preliminary occupational exposure risk assessment; (2) linear discriminant function analysis (LDA) may be ...

  • The rhizotoxicity of metal cations is related to their strength of binding to hard ligands

    Mechanisms whereby metal cations are toxic to plant roots remain largely unknown. Aluminum, for example, has been recognised as rhizotoxic for about 100 years but there is no consensus on its mode of action. We contend that the primary mechanism of rhizotoxicity of many metal cations is non‐specific and that the magnitude of toxic effects is positively related to the strength with which they ...
