  • 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 ...

  • 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 ...

  • Limitation of hardness from thermal water by means of nanofiltration

    Geothermal conditions are extremely favourable in Hungary. Thermal water is accessible in 70% of the territory of the country, with a lowest temperature of 30°C. For energetic purposes, it can be utilized in two different ways: for supplying heat or generating electricity. In relation to utilization, one of the most serious problems derives from the chemical composition of thermal ...

  • Catalytic hard water scale prevention system saves thousands of dollars

    The Western Technology Center in Oklahoma was experiencing ongoing scaling issues in their cafeteria building requiring costly planned maintenance and chemical use.  Six Rinnai tankless water heaters had to be descaled every month with the cleaning process requiring most of one day.  The heaters are fitted with keypads that flash a “descale required” code when ...

  • 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 ...

  • Manganese (Mn) toxicity to tropical freshwater species in low hardness water

    Elevated Manganese (Mn) is a common contaminant issue for mine water discharges and previous studies have reported that its toxicity is ameliorated by H + , Ca2+ and Mg2+ ions. The toxicity of manganese (Mn) was assessed in a high risk scenario, i.e. the slightly acidic, soft waters of Magela Creek, Kakadu National Park, Northern Territory, Australia. Toxicity estimates were derived for six ...

  • How can I measure temporary and permanent water hardness?

    Hard water is water with high levels of dissolved minerals, and usually occurs in areas where limestone and chalk are common. These minerals can be divided into two types, and so hardness is often considered in two categories – permanent and temporary water hardness. So how can we measure water hardness? Can we measure temporary and permanent ...

  • 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 ...

  • 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 ...

  • 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 ...

  • A Guide To Buy Large Area Hard Floor Cleaners

    Hard floor cleaning machines can be classified into small area cleaning machines and large area hard floor cleaners. What is much in the cleaning area, one might ask. The same machine that can be used to clean a small area can be used for cleaning larger areas. While it is technically true, it may not be practically feasible. What are Hard Floor Cleaning Machines? A variety of ...

  • Three Tips to Use Hard Surface Furniture Cleaners

    Hard surface furniture cleaners are not the same as hard surface cleaners. Normally, we associate pressure washers with cleaning hard surfaces. These machines pump their output onto hard surfaces to blast away dirt and substances present on hard surface. This mode of operation is not suitable for cleaning furniture surfaces, no matter how hard they may be, due to two reasons. First, furniture ...
