Water contamination is one of the most common and damaging issues in diesel fuel storage and use. Diesel—particularly modern ultra-low sulfur diesel (ULSD) and biodiesel blends—is hygroscopic, meaning it naturally attracts and absorbs moisture from the surrounding air at a molecular level. This makes water ingress almost inevitable over time, especially in stored ...
Introduction: Railways as the Lifeline of India’s Infrastructure India has one of the world’s largest railway networks, covering over 68,000 kilometers and transporting nearly 8 billion passengers and over a billion tons of freight annually (Ministry of Railways, 2023). With the increasing axle loads, higher train speeds, and frequent schedules, railway infrastructure today demands ...
Whether you call it climate change, global warming, the greenhouse effect-or something else entirely-it’s no longer possible to deny the impact human activity has had on our planet. Since 1880, the planet’s temperature has risen, on average, by 0.08 degrees Celsius (0.14 degrees Fahrenheit)-with the 10 warmest years on record occurring since 2010. The products we manufacture, the ...
According to relevant researches, the following describes the important applications of several common polymers in medicine science. 1 Surgical suture Due to its biodegradability and absorbability in the body,polylactic acid and its copolymers can be used as surgical sutures to promote wound healing and can be automatically degraded and absorbed ...
In order to answer this question, we first need to realize that BOD, although a biochemical testing procedure where microorganisms’ oxygen consumption over 5 days or more is measured, is essentially an estimate of biodegradable organics in the water. Like other organics present in the water, biodegradable organics also absorb UV light, and ...
With over 200 installations across Ireland, Real Tech in partnership with Glan Agua, are helping to improve process control and drinking water quality. Simple and affordable real-time UV254 organics analyzers from Real Tech are enabling plants to rapidly detect organic fluctuations in raw water and take action to ensure effective removal is achieved. Background UV254 provides one of the best ...
According to the American Society of Civil Engineers’ Report Card for America’s Infrastructure, municipalities are at a higher risk of stormwater runoff than ever before. More than 60% of the nation’s stormwater utilities have significant concerns about aging infrastructure handling long-term stormwater runoff control needs. Flooding is among the top three most costly and common ...
Search for calcium alginates dressings and virtually every literature source will describe its long list of properties: highly absorbent, biocompatible, biodegradable, high strength, high integrity, and low fibre shed.1 One property that seems to be consistently missed off the list though is its haemostatic ability. ...
Trench drain systems come in all shapes, sizes and materials and it can be difficult to determine which system is best suited for your project. Here’s a breakdown on what you need to consider when planning a project that requires trench drain systems. What are the load requirements for the drain? It’s particularly important to mitigate potential flooding situations in high ...
After successful performance evaluations, the U.S. Department of Defense (DoD) Defense Logistics Agency (DLA) has officially introduced soy biobased penetrating lubricants and a spill sorbent into the federal buying system. Now DLA customers can easily identify and buy these soy biobased products as an alternative to petroleum-based counterparts with the knowledge that they meet DoD product ...
Summary: In a nine week study, a bio-based oil absorbent, Nature's Broom Plus, was evaluated for its ability to stimulate the degradation of petroleum products in used motor oil and hydraulic fluid. There were three treatments: 1) controls containing only Nature's Broom Plus and de-ionized water, 2) Nature's Broom Plus contaminated with - 20,000 ppm of Havoline motor oil and de-ionized water and ...
Filtration stages along the operation have been monitored, measuring parameters such DOC (Dissolved Organic Carbon), UVabs (ultraviolet absorbance), BDOC (Biodegradable Organic Carbon) and AOC (Assimilable Organic Carbon). ...

Coal is a porous medium and natural absorbent. It can be used for its original purpose after adsorbing organic compounds, its value does not reduce and the pollutants are recycled, and then through systemic circulation of coking wastewater zero emissions can be achieved. Thus, a novel method of industrial organic wastewater treatment using adsorption on coal is introduced. Coking coal was ...
One of the major environmental problems is the existence of dye materials in water sources. This pollutant must be removed from water by appropriate methods. Although most of these methods are efficient for the treatment of waters contaminated with dye pollutants, they are very costly and commercially unattractive. Adsorption is one of the most popular methods for the removal of dye ...
What is an Interceptor Tank? An interceptor tank is a trap used to filter out hydrocarbon pollutants from rainwater runoff. It is typically used in road construction and on petrol station forecourts to prevent fuel contamination of the water table via runoff. Petrol interceptors work on the premise that some hydrocarbons such as petrol and diesel float on the top of water. The contaminated ...
This year’s Earth Day will be held on April 22nd, and will be the 46th event of its kind. The event brings together people from all over the world to raise awareness, support and participation for environmental protection. This year’s event has a specific goal, dubbed ‘Trees for Earth’, which aims to plant 7.8 billion trees by 2020. This ambitious goal is part of the ...
Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus different gas molecules have different natural ...
Europe is bound to the rest of the world through multiple systems that enable two-way flows of materials, financial resources, ideas and innovation. As a result, Europe's economic, ecological and societal resilience is and will continue to be significantly affected by a variety of global and interdependent social, economic, political, environmental and technological trends. Global material ...
The world is about to go on a carbon diet. It won't be easy - or cheap. Nearly 200 nations across the world on Saturday approved a first-of-its-kind universal agreement to wean Earth off fossil fuels and slow global warming, patting themselves on the back for showing such resolve. On Sunday morning, like for many first day dieters, the reality sets in. The numbers - like calorie limits and ...
