  • Case Study PHE (Plate Heat Exchanger) test results in hard water region

    Industry, hotels, commercial buildings even private homes in "Hard" water areas are at a disadvantage due to "Scale" formation on devices, particularly those attached to "Hot" water circuits.  A PHE (Plate Heat Exchanger) with a known "Scaling" problem is selected for testing. The attached case study demonstrates how with an "Open" mind, even those sceptical of our products ...

  • 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 ...

  • How Do You Choose the Best Reverse Osmosis and Nanofiltration Membrane System for an Industrial Facility?

    As global demands for clean water increase, more and more industrial facilities are looking toward membrane filtration solutions, such as reverse osmosis (RO) and nanofiltration (NF), to help manage intake, process, and waste water treatment. Using membrane filtration can help your facility reuse wastewater and virtually eliminate discharge fees, and depending on the industry or required use, it ...

  • 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 ...

  • Integrating soft and hard risks

    All organisations need continually to improve and make efficiency savings without introducing unacceptable risks. Savings can be made by new collaborations and sharing at the interface between processes. Processes are what people do and so we use them to deliver value. We can also think and use process differently to improve performance. To identify added value we use a process map which shows ...

  • Invention of the Tire Shredder

    The process of vulcanizing rubber was discovered by Charles Goodyear (yes, you read that right) in 1839, and the development of rubber tires followed not long after (Source: Continental Truck). From there, it didn’t take long for worn-out tires to start piling up, and finding good ways to ...

  • 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 ...

  • Tradition dies hard

    Traditions in the way we view our environment are strongly entrenched in our collective mind, and any perturbation that could change them is usually strongly resisted.  However, change does occur [1], even though there is resistance to it, and this includes changes in the scientific process as well. Science is continually developing, with advances replacing what was previously envisioned to be ...

  • 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 ...

  • What can you achieve with a solar system and battery?

    People often ask us about energy self-sufficiency. Just how hard is it to get to that point where you no longer have to pay a large corporation each time you turn on the kettle? This will depend on your usage patterns but for most people, a mix of renewable systems is the best option. We’ve taken a look at Gabriel’s home renewable systems as an example. Perhaps unsurprisingly, Gabriel ...

  • Grazing effects on yield and quality of hard red and hard white winter wheat

    Six hard red (2137, Jagalene, Jagger, OK101, Stanton, and Thunderbolt) and six hard white (Burchett, Lakin, NuFrontier, NuHills, NuHorizon, and Trego) winter wheat (Triticum aestivum L.) varieties were evaluated for grain yield and quality in southwestern Kansas in 2004 and 2005. Cattle commonly graze wheat in this region from late November to mid March in a dual-purpose system. The experimental ...

  • Characters of Soft or Hard Seal Valves

    Soft and hard seal are able to complement each other. The seal ability of soft one is better than hard one, however, hard seal now can also meet some requirements. Soft seal has better sealing ability, but can easily age, wear and has a short lifespan. Hard seal can be used longer, but has poorer sealing ability. Characters of Soft Seal Valves Soft seal: one side of the seal is ...

  • Dietary effect on GHG emissions is hard to swallow

    The news is enough to make climate campaigners choke on their high-fibre breakfast cereal: if Americans adopted the dietary guidelines suggested by their own Department of Agriculture, greenhouse gas emissions (GHGs) would actually go up by 12%. And even if Americans did what dietary ...

  • Things to Consider When Choosing A Hard Floor Cleaner

    A hard floor cleaner can be a good investment for any commercial or industrial area, provided you opt for the right kind of machine. Carpet cleaning is given a lot of focus and attention As compared to hard flooring, which sometimes gets the “step-daughterly” treatment, since these surfaces are relatively easy to wipe. If a spill can be wiped off the surface, there is a common ...

  • 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 ...

  • 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 ...
