  • Do you know the two most important words required to understand oil spill booming?

    Much has been written (incorrectly) about how to deploy boom in order to protect, deflect or contain oil. We have long promoted using math and science when deploying spill countermeasures not only because it works, but because it’s faster, safer, more effective and it saves time, money and impact. What we’ll focus on in this article is the where of ...

  • Confirming Natural Attenuation Processes at a Coastal Site - Case Study

    Past waste disposal practices at a California coastal site resulted in a groundwater plume containing CVOCs (mainly chlorinated ethenes [CEs] and 1,1-dichloroethane) migrating offshore towards a marine harbor. CVOCs are present in the sediment porewater adjacent to the shoreline, but concentrations decreased significantly between 2000 and 2015, and NA in the marine sediments was suspected. To ...

  • 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 Seismic Use Group Classification affects your Water Storage Tank

    When purchasing a bolted steel tank or a welded steel water storage tank, one of the key criteria determining the design parameters of the tank is the Seismic Use Group (SUG) classification. The term Seismic Use Group is essentially the same as the terms Occupancy Category and Risk Category used by the International Building Code (IBC) and the ...

  • 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 ...

  • Evaporative cooling cuts energy costs

    Commercial contractors utilize alternative technology in today’s buildings It is estimated that HVAC systems account for approximately 40 percent of the energy used in commercial buildings, which is why many building owners and managers are looking for ways to cut these costs. One way to do that may be to utilize evaporative cooling systems, which can be relatively inexpensive to ...

  • Oil Recycling - Case Study

    The problem: Waste oil recycling contributes very much to climate protection through (CO2) energy saving. Compared to the production of base oil the re-refining of waste oil uses 34 % less resources. In the sixties the German government was subsidising the re-refining of waste oil. Because of that the use of waste oil as a fuel was neglected. The used oil re-refining is the ...

  • Sterile wastewater treatment with vacuum distillation

    Hygiene requirements are growing increasingly strict in many sectors, and the treatment of industrial wastewater is no exception. The vacuum distillation process in particular has to deal with the question of sterile treatment and subsequent storage of water obtained from the process. The mere possibility of reintroducing wastewater into the production process makes it imperative to prevent ...

  • Tetrapak, Alfa Laval, Westfalia, Cream separators and Sialex®Ring - Case Study

    Tipperary Co-operative, use Sialex®Ring to help control "Scaling" on Plate Heat and Shell and Tube heat exchangers on their " hot water circuits". A further area suitable to benefit from Sialex® is in the Cream separators. These devices are prone to "Scale" build up on flushing jets. Cleaning requires did-assembly and cleaning. This can occur several times during a year. Platetek ...

  • Kansas Facility Finds Fast, Reliable Fix to Cavitation Damage

    The Hutchinson (Kansas) Water Plant gets its water from 20 wells. The water is pumped out of the wells and into a reverse osmosis water treatment center to purify and ensure safe drinking water. At that point, a portion of the water is taken off from the main line, run through the reverse osmosis system and then mixed back ...

  • 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 ...
