  • 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 ...

  • The Myth of Heat Illnesses

    If you have not already had a safety talk in your workplace about heat stress and related illnesses, you probably will have one in the coming weeks.  Summer is around the corner and temperatures are warming up.  You will probably hear something about becoming acclimated to the heat slowly, and drinking plenty of water. But if that’s all that you have been told about warm outdoor ...

  • Technical and economic evaluation of an off-grid solar desalination system in Myanmar

    Myanmar is a unique country where the majority of the people live in rural areas, away from grid electricity and reliable water supplies. The penetration of grid electricity in rural areas is minimal and even then it is often erratic. This paper focuses on the challenges of transitioning from an electricity-poor country to a renewable energy based-economy augmented with photovoltaics (PV). ...

  • Africa’s green energy challenge: Mega projects, off-grid or somewhere in between?

    South of the Sahara, getting electricity to 620 million people may require an all-of-the-above strategy. A 310-megawatt wind farm sprouting up in a remote, barren landscape near Lake Turkana in northern Kenya has the clean energy world buzzing — and for good reason. Africa’s largest wind farm, with 365 towering turbines, is creating more than 500 stable jobs in an ...

  • 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 ...

  • 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 ...

  • Titanium Demand on Rise for Additive Manufacturing Printing: How it’s Made? Titanium Plasma Atomization.

    Plasma atomization is used in many applications, including 3D printing. First developed in 1998, this technique has risen to become the industry standard process for creating reactive metal powders suitable for 3D printing. Learn how plasma atomization works and why you need an oxygen monitor to stay safe with plasma atomization.  How Plasma Atomization Works ...

  • Hourly water demand forecasting for micro water grids

    Many countries have problems related to water scarcity and are thus seeking to promote greater water efficiency. A micro water grid (MWG) is a high-efficiency water management system that integrates information and communication technologies (ICT) for the water distribution systems in individual buildings. More accurate forecasting of hourly water demand is necessary if these systems are to ...

  • Biotreatment of off-gases from a waste water buffer

    1. The Problem As on alternative to an initially planned adsorptive treatment by activated carbon of gases emitted by a buffer for from industrial effluents, also a biological treatment had been was investigated. 2. Solution of the problem Treating the off-gases in a two-stage bio-trickling filter using microorganisms attached to LEVAPOR carrier the problem has ...

  • Application of the LBM with adaptive grid on water hammer simulation

    A lattice Boltzmann method (LBM) is utilized to solve single-phase transient flow in pipes. In order to eliminate grid limitation related to the method of characteristics, governing equations are modified using appropriate coordinate transformation. The introduced modification removes connection between Courant number and spatial disposition of the computational nodes, forming a more flexible ...

  • Taking the pressure off desalination

    California-based PAX Pure hopes to offer a new solution to water scarcity with its groundbreaking water purification tool. Developed by Jay Harman and Tom Gielda, PAX Pure technology desalinates and demineralizes water without membranes, moving parts or chemicals. Instead, the technology simply mimics high-altitude conditions. The big challenge with conventional ...

  • Smart Grid: The game

    In his best seller “Outliers,” Malcolm Gladwell shows that it is not equipment failure or storms that typically cause planes to crash, but wrong decision-making. Much the same can be said for the power grid crash that took down a large swath of the Northeast in August 2003. The emerging smart grid is supposed to make our power system more reliable. The bad news is that it also will add complexity ...

  • Excavation, Retrieval, and Off-Site Disposal

    Introduction: Contaminated material is removed and transported to permitted off-site treatment and/or disposal facilities. Some pretreatment of the contaminated media usually is required in order to meet land disposal restrictions. Confined disposal facilities (CDFs) are engineered structure enclosed by dikes and designed to retain dredged materials. A CDF may have a large cell for ...

  • Grid Connection An open letter to those on grid considering pursuing hydro power

    Many people contact us concerning the possibility of using a power source that is either connected to the commercial power grid or feeding power to a house that is. While this may be possible, it is not likely to make economic sense. Over 99% of our customers are off-grid and there are reasons for this. The question is then more like: ’Can I put in a small hydro system or should I spend ...
