  • How Tire Shredding Protects Wildlife

    One of the most revolutionary inventions in the history of mankind was the wheel, and the best upgrade to that invention was the rubber tire, which overcame the limitations of wooden or metal wheels and made it possible to have smooth rides at fast speeds. However, there is a significant drawback to using rubber tires: eventually, they get too worn out to be useful as tires anymore and have to ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • 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 ...

  • 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 ...

  • 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). ...

  • Matthew Orosz awarded Echoing Green Fellowship to further off-grid energy work

    Newly minted MIT PhD selected for two-year social entrepreneurship fellowship. Written by Nathan Birnbaum.You can read the original new in MIT NewsMatthew Orosz MEng '03, SM '06, PhD '12 had a lot to be proud of on June 7. Not only was he invested with ...

  • 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 ...

  • Solar hot water system

    Solar hot water systems (e.g. residential) do not produce steam, for example. Thus, solar hot water systems cannot push a steam turbine and will not generate electrical power. Solar hot water systems are used for heating and hot water requirements, not electrical power. If this is offsetting electrical hot water or electrical heat, then these are more like 'negawatts' than Terawatts. Steam ...


  • 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 ...

  • National Grid, Croydon case study

  • 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 ...

  • Water treatment technology for produced water

    Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined ...

  • Efficacy of drinking-water treatment residual in controlling off-site phosphorus losses: A field study in Florida

    Received for publication August 23, 2008. Land application of drinking-water treatment residuals (WTR) has been shown to control excess soil soluble P and can reduce off-site P losses to surface and ground water. To our knowledge, no field study has directly evaluated the impacts of land application of WTRs on ground water quality. We monitored the effects of three organic sources of P (poultry ...

  • Nationwide survey of organism-related off-flavor problems in Japanese drinking water treatment plants (2010–2012)

    Recent trends in off-flavor problems were investigated by a nationwide questionnaire survey targeting 239 drinking water treatment plants (DWTPs) maintained by 79 regional water suppliers (RWS) in Japan. The results indicated that 43 of 79 (54%) RWS and 89 of 239 (36%) DWTPs were affected by off-flavor problems in a recent 2-year period (October 2010–September 2012). Off-flavor incidents ...

  • Evaluation of approaches for consumers to eliminate chlorine off-flavors from drinking water at point-of-use

    Chlorine off-flavors of tap water have caused dissatisfaction and distrust from some consumers, placing pressure on operators concerning water disinfection. Evaluating practical approaches for eliminating chlorinous off-flavors by consumers at point-of-use while avoiding production of toxic byproducts is a practical concern. Three recognized dechlorination methods: ultraviolet (UV) irradiation, ...
